[0115] Please see Figure 1 This application provides a specific embodiment of a 3D printing consumable switching method, applied to a consumable switching device, which receives consumables transmitted from a consumable input device.

[0116] Step 10: Obtain printing information, which should include at least the type of printing consumables.

[0117] In the field of 3D printing, 3D printers print based on the information of the printing model, which may include information such as the model's structure, color, and consumable material. In this application, the consumable category information includes consumable color information, consumable material information, consumable production information, and other information related to consumable attributes. The 3D printer can select the corresponding consumable for printing based on this consumable category information of color or material.

[0118] Step 20: In response to the change of printing consumable category information from first consumable category information to second consumable category information, based on the position of the second consumable corresponding to the second consumable category information in the consumable input device and the current alignment state between the consumable switching device and the consumable input device, switch the consumable switching device to the second alignment state with the consumable input device. The second alignment state is used to guide the consumable corresponding to the second consumable category information in the consumable input device to the 3D printer.

[0119] The alignment state is when the filament switching device simultaneously outputs at least two types of filaments to the 3D printer.

[0120] It should be noted that the alignment state includes the current alignment state and the second alignment state. It can be understood that the alignment state is when the consumable switching device receives the consumable transmitted by the consumable input device and conducts the received consumable to the 3D printer.

[0121] Among them, the printing consumables category information changes from the first consumables category information to the second consumables category information. Specifically, the printing consumables can be switched from the consumables corresponding to the first consumables category information to the consumables corresponding to the second consumables category information. That is, the 3D printer needs to switch from the current printing consumables to the next type of printing consumables.

[0122] Based on the position of the consumable corresponding to the second consumable category information in the consumable input device and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to the second alignment state with the consumable input device. This can be understood as the need to switch one of the two consumables in the consumable switching device to the other and output it to the corresponding position on the 3D printer. This requires switching based on the current alignment state between the consumable switching device and the consumable input device so that the two consumables can be correctly output to the corresponding positions on the 3D printer.

[0123] In practical applications, such as 3D printers that output two types of consumables simultaneously, the 3D printer has two printheads or sprue structures that receive the two types of consumables respectively, with each type of consumable entering a printhead to prepare for or print.

[0124] It should be noted that the consumable input device can refer to a device that provides printing consumables to the consumable switching device. The consumables in the consumable input device can be consumables fed into the consumable input device by a device with feeding power, such as a feeding hopper. The consumables can be powered by a feeding hopper to be fed into the consumable switching device. The consumable input device only provides the function of guiding consumables into the consumable switching device. Alternatively, the consumables can be powered by the consumable input device to be fed into the consumable switching device. In short, the function of the consumable input device is to provide printing consumables to the consumable switching device.

[0125] This application embodiment achieves the output of the two types of consumables currently being printed and those to be printed to the corresponding print heads of the 3D printer by switching the alignment state of the consumable switching device. This enables multiple consumables to be input to the two print heads of the 3D printer through the consumable switching device. Only one set of consumables of different colors and the consumable switching device are needed. The consumable switching device can deliver all the consumables of different colors to the corresponding print heads of the 3D printer, improving the utilization rate of consumables and the device.

[0126] Based on the examples above, some specific possible implementation examples will be provided below. In practical applications, the implementation content of these examples can be combined or implemented separately as needed according to the corresponding functional principles and application logic, depending on the actual scenario.

[0127] In one optional embodiment of the present invention, the second alignment state is the same as the current alignment state, and switching the consumable switching device to the second alignment state with the consumable input device includes:

[0128] The position of the consumable switching device is kept in place so that the alignment state between the consumable switching device and the consumable input device is the current alignment state.

[0129] If the second alignment state differs from the current alignment state, the consumable switching device is switched to the second alignment state with the consumable input device, including:

[0130] Control the operation of the consumable switching device to make the alignment state between the consumable switching device and the consumable input device a second alignment state.

[0131] It should be noted that, based on the position of the second consumable corresponding to the second consumable category information in the consumable input device and the current alignment state of the consumable switching device and the consumable input device, the second alignment state of the consumable switching device can be the same as the current alignment state. For example, when the printing consumable category information changes from the first consumable category information to the second consumable category information, the two consumables p1 and p2 in the current alignment state are switched to the two consumables p2 and p3 in the second alignment state. At this time, the alignment state of consumables p2 and p3 corresponding to the 3D printer is the same as the alignment state of consumables p1 and p2 corresponding to the 3D printer. That is, the second alignment state of the consumable switching device can be the same as the current alignment state. At this time, the second alignment state is the current alignment state. When the second alignment state of the consumable switching device is different from the current alignment state, the consumable switching device is controlled to move to switch the state so that the alignment state of the consumable switching device and the consumable input device is the second alignment state.

[0132] In one optional embodiment of the present invention, the consumable switching device includes at least two sets of movable consumable channels, and the second alignment state is different from the current alignment state;

[0133] Controlling the operation of the consumable switching device to make the alignment state between the consumable switching device and the consumable input device a second alignment state includes moving the position of at least one set of consumable channels in at least two sets of movable positions so that the input channel corresponding to the second consumable category information in the consumable input device is aligned with the position of the consumable channel corresponding to the second consumable category information in at least two sets of movable positions.

[0134] In practical applications, the consumable switching device can move the position of the group of consumable channels containing the second consumable channel corresponding to the second consumable category information. For example, it can move the group of consumable channels corresponding to the second consumable category information from the first position to the second position or from the second position to the first position, so as to align the consumable channel corresponding to the second consumable category information in the consumable input device with the position of the consumable channel corresponding to the second consumable category information in at least two groups of movable consumable channels. This allows the consumable corresponding to the second consumable category information in the consumable input device to be imported into the corresponding consumable channel in the consumable switching device, and the consumable switching device to export the consumable to the corresponding position on the 3D printer.

[0135] In one optional embodiment of the present invention, the consumable switching device includes at least two sets of movable consumable channels, the position of one set of consumable channels includes a first position and a second position, and the alignment state includes at most two sets of consumable channels being located in the second position;

[0136] Maintaining the position of the consumable switching device in its original position so that the alignment state between the consumable switching device and the consumable input device is the current alignment state includes:

[0137] The consumable channel corresponding to a set of movable positions for the second consumable category information is kept in the first position or in the second position;

[0138] For example, when the printing consumable category information changes from the first consumable category information to the second consumable category information, the two consumables p1 and p2 in the current alignment state are switched to the two consumables p2 and p3 in the second alignment state. At this time, the alignment state of consumables p2 and p3 corresponding to the 3D printer is the same as the alignment state of consumables p1 and p2 corresponding to the 3D printer. The position of the consumable switching device is kept in its original position. That is, if the consumable channel corresponding to the second consumable category information is in the first position in the current alignment state, it will remain in the first position. If the consumable channel corresponding to the second consumable category information is in the second position in the current alignment state, it will remain in the second position.

[0139] Controlling the operation of the consumable switching device to achieve a second alignment state between the consumable switching device and the consumable input device includes:

[0140] Control the set of movable consumable channels corresponding to the second consumable category information to switch from the first position to the second position, or from the second position to the first position;

[0141] For example, when the printing consumable category information changes from the first consumable category information to the second consumable category information, the two consumables p1 and p2 in the current alignment state are switched to the two consumables p2 and p3 in the second alignment state. At this time, the alignment state of consumables p2 and p3 corresponding to the 3D printer is different from the alignment state of consumables p1 and p2 corresponding to the 3D printer. The consumable switching device is controlled to move, so that the consumable channel corresponding to the second consumable category information moves its position. That is, the consumable channel corresponding to the second consumable category information is switched from the first position in the current alignment state to the second position, and the consumable channel corresponding to the second consumable category information is switched from the second position in the current alignment state to the first position.

[0142] It should be noted that the first and second positions here are not particularly limited, and can be two positions of a set of consumable channels when moving in a straight line;

[0143] For example, a set of consumable channels includes two parallel straight channels and two intersecting channels in the vertical direction. The first position can be the position of the straight channel corresponding to the consumable input device, and the second position is the position of the intersecting channel corresponding to the consumable input device; or, the first position can be the position of the intersecting channel corresponding to the consumable input device, and the second position is the position of the straight channel corresponding to the consumable input device.

[0144] In one optional embodiment of the present invention, the consumable switching device includes at least two sets of movable consumable channels. Each set of consumable channels has a first position and a second position. The current alignment state includes at most two sets of consumable channels being in the second position, and includes position A, position B, and position C. Position A is when at least two sets of consumable channels are both in the first position, for example, when at least two sets of movable consumable channels are both in the initial state. Position B is when one set of the at least two sets of movable consumable channels is in the second position, for example, when one set of the at least two sets of movable consumable channels switches from the first position to the second position, while the remaining sets of consumable channels remain in the first position. Position C is when two sets of the at least two sets of movable consumable channels are in the second position, for example, when two sets of the at least two sets of movable consumable channels switch from the first position to the second position, while the remaining sets of consumable channels remain in the first position.

[0145] In one optional embodiment of the present invention, the consumable input device includes at least two sets of horizontally parallel input channels, one set of input channels including two vertically parallel input channels; the first consumable corresponding to the first consumable category information is located in the set of consumable channels in the second position;

[0146] When the current alignment state is position A.

[0147] Based on the position of the second consumable corresponding to the second consumable category information in the consumable input device, and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to the second alignment state with the consumable input device, specifically including:

[0148] When the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are both located in the upper input channel of the consumable input device or both located in the lower input channel of the consumable input device, the consumable channel corresponding to a set of movable positions of the second consumable category information is controlled to switch from the first position to the second position.

[0149] It should be noted that, for example, the attached document... Figure 9 As shown, the consumable corresponding to the first consumable category information is consumable B, the consumable corresponding to the second consumable category information is consumable C, and consumable A is the other one of the two consumables in the current alignment state, that is, the original two consumables A and B are switched to consumables B and C.

[0150] When the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are respectively located in the upper input channel and the lower input channel of the consumable input device, the A position state is maintained as the second alignment state.

[0151] It should be noted that, for example, the attached document... Figure 14 As shown, the consumable corresponding to the first consumable category information is consumable B, the consumable corresponding to the second consumable category information is consumable C, and consumable A is the other one of the two consumables in the current alignment state, that is, the original two consumables A and B are switched to consumables B and C.

[0152] It should be noted that "the first consumable location corresponding to the first consumable category information and the second consumable location corresponding to the second consumable category information are located in the upper and lower channels of the consumable input device, respectively," which means...

[0153] "The first consumable location corresponding to the first consumable category information is located in one of the upper channel and the lower channel of the consumable input device; the second consumable location corresponding to the second consumable category information is located in the other of the upper channel and the lower channel of the consumable input device."

[0154] It should also be noted that when a consumable is removed from a consumable channel in the second position, leaving that channel empty, the channel automatically switches from the second position to the first position. For example, if the initial position of the consumable channel is the first position, and a consumable is introduced when it switches to the second position, the channel automatically switches back to the first position when the consumable is removed from the second position. If a consumable is present in the consumable channel in the second position, the channel does not need to switch back to the first position.

[0155] In one optional embodiment of the present invention, the consumable input device includes at least two sets of horizontally parallel input channels, and one set of input channels includes two vertically parallel input channels; when the current alignment state is position B,

[0156] Based on the position of the second consumable corresponding to the second consumable category information in the consumable input device, and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to the second alignment state with the consumable input device, specifically including:

[0157] When the first consumable position corresponding to the first consumable category information is in the same group of consumable channels located in the second position, if the second consumable position corresponding to the second consumable category information is in the same group of consumable channels located in the second position, the consumable channels in the same group of movable positions corresponding to the second consumable category information remain unchanged.

[0158] It should be noted that if the first consumable corresponding to the first consumable category information and the second consumable corresponding to the second consumable category information are both in the same group of consumable channels, then the B position state is maintained as the second alignment state.

[0159] It should be noted that, for example, the attached document... Figure 15 As shown, the consumable corresponding to the first consumable category information is consumable E, the consumable corresponding to the second consumable category information is consumable F, and consumable D is the other one of the two consumables in the current alignment state, that is, the original two consumables D and E are switched to consumables E and F.

[0160] It should be noted that, for example, the attached document... Figure 10 As shown,

[0161] When the first consumable position corresponding to the first consumable category information is in the group of consumable channels located in the second position, if the second consumable position corresponding to the second consumable category information is in one of the group of consumable channels located in the first position, and the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are simultaneously in the upper input channel of the consumable input device, or simultaneously in the lower input channel of the consumable input device, then the group of movable consumable channels corresponding to the second consumable category information remains unchanged.

[0162] It should be noted that, for example, the attached document... Figure 16 As shown, the consumable corresponding to the first consumable category information is consumable E, the consumable corresponding to the second consumable category information is consumable F, and consumable D is the other one of the two consumables in the current alignment state, that is, the original two consumables D and E are switched to consumables E and F; when the first consumable position corresponding to the first consumable category information is in the group of consumable channels in the second position, if the second consumable position corresponding to the second consumable category information is in one of the group of consumable channels in the first position, the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are respectively in the upper input channel and the lower input channel of the consumable input device, and the group of movable consumable channels corresponding to the second consumable category information are switched from the first position to the second position;

[0163] It should be noted that "the first consumable location corresponding to the first consumable category information and the second consumable location corresponding to the second consumable category information are located in the upper and lower channels of the consumable input device, respectively," which means...

[0164] "The first consumable location corresponding to the first consumable category information is located in one of the upper channel and the lower channel of the consumable input device; the second consumable location corresponding to the second consumable category information is located in the other of the upper channel and the lower channel of the consumable input device."

[0165] It should be noted that, for example, the attached document... Figure 10 As shown, the consumable corresponding to the first consumable category information is consumable E, the consumable corresponding to the second consumable category information is consumable F, and consumable D is the other one of the two consumables in the current alignment state, that is, the original two consumables D and E are switched to consumables E and F.

[0166] When the first consumable position corresponding to the first consumable category information is in one of the consumable channels located in the first position, if the second consumable position corresponding to the second consumable category information is in one of the consumable channels located in the first position, and the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are simultaneously in the upper input channel of the consumable input device, or simultaneously in the lower input channel of the consumable input device, the consumable channel in one movable position corresponding to the second consumable category information is controlled to switch from the first position to the second position;

[0167] It should be noted that, for example, the attached document... Figure 17 As shown, the consumable corresponding to the first consumable category information is consumable E, the consumable corresponding to the second consumable category information is consumable F, and consumable D is the other one of the two consumables in the current alignment state, that is, the original two consumables D and E are switched to consumables E and F.

[0168] When the first consumable position corresponding to the first consumable category information is in one of the consumable channels located in the first position, if the second consumable position corresponding to the second consumable category information is in one of the consumable channels located in the first position, the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are respectively located in the upper input channel and the lower input channel of the consumable input device, and the consumable channel corresponding to the second consumable category information is controlled to remain in the first position.

[0169] It should be noted that "the first consumable location corresponding to the first consumable category information and the second consumable location corresponding to the second consumable category information are located in the upper and lower channels of the consumable input device, respectively," which means...

[0170] "The first consumable location corresponding to the first consumable category information is located in one of the upper channel and the lower channel of the consumable input device; the second consumable location corresponding to the second consumable category information is located in the other of the upper channel and the lower channel of the consumable input device."

[0171] It should be noted that, for example, the attached document... Figure 18As shown, the consumable corresponding to the first consumable category information is consumable E, the consumable corresponding to the second consumable category information is consumable F, and consumable D is the other one of the two consumables in the current alignment state, that is, the original two consumables D and E are switched to consumables E and F.

[0172] It should be noted that when a consumable is removed from a set of consumable channels in the second position, the set of consumable channels switches from the second position to the first position. That is, when there is no consumable in a set of consumable channels in the second position, the set of consumable channels automatically switches from the second position to the first position. For example, the initial position of the set of consumable channels is the first position. When it switches to the second position, a consumable is introduced. When the consumable is removed from the set of consumable channels in the second position, the set of consumable channels switches from the second position to the first position.

[0173] In one optional embodiment of the present invention, when the current alignment state is position C, the consumable input device includes at least two sets of horizontally parallel input channels, and one set of input channels includes two vertically parallel input channels; the first consumable corresponding to the first consumable category information is located in the set of consumable channels in the second position.

[0174] Based on the position of the second consumable corresponding to the second consumable category information in the consumable input device, and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to the second alignment state with the consumable input device, specifically including:

[0175] If the second consumable position corresponding to the second consumable category information is located in the group of consumable channels in the second position, and the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are respectively located in the upper input channel and the lower input channel of the consumable input device, the group of movable consumable channels corresponding to the second consumable category information remains in the second position.

[0176] It should be noted that, for example, the attached document... Figure 19 As shown, the consumable corresponding to the first consumable category information is H consumable, the consumable corresponding to the second consumable category information is I consumable, and G consumable is the other one of the two consumables in the current alignment state, that is, the original two consumables G consumable and H consumable are switched to H consumable and I consumable.

[0177] If the second consumable position corresponding to the second consumable category information is located in the group of consumable channels in the second position, and the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are both located in the upper input channel of the consumable input device or both located in the lower input channel of the consumable input device, the group of movable consumable channels corresponding to the second consumable category information is switched from the second position to the first position.

[0178] It should be noted that, for example, the attached document... Figure 20 As shown, the consumable corresponding to the first consumable category information is H consumable, the consumable corresponding to the second consumable category information is I consumable, and G consumable is the other one of the two consumables in the current alignment state, that is, the original two consumables G consumable and H consumable are switched to H consumable and I consumable.

[0179] If the second consumable position corresponding to the second consumable category information is in one of the consumable channels located in the first position, and the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are respectively located in the upper input channel and the lower input channel of the consumable input device, the consumable channel in the movable position corresponding to the second consumable category information is switched from the first position to the second position.

[0180] It should be noted that "the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are respectively located in the upper channel and lower channel of the consumable input device," which means...

[0181] "The first consumable location corresponding to the first consumable category information is located in one of the upper channel and the lower channel of the consumable input device; the second consumable location corresponding to the second consumable category information is located in the other of the upper channel and the lower channel of the consumable input device."

[0182] It should be noted that, for example, the attached document... Figure 11 As shown, the consumable corresponding to the first consumable category information is H consumable, the consumable corresponding to the second consumable category information is I consumable, and G consumable is the other one of the two consumables in the current alignment state, that is, the original two consumables G consumable and H consumable are switched to H consumable and I consumable.

[0183] If the second consumable position corresponding to the second consumable category information is in one of the consumable channels located in the first position, and the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are simultaneously located in the upper input channel of the consumable input device, or simultaneously located in the lower input channel of the consumable input device, the consumable channel of the movable position corresponding to the second consumable category information remains in the first position.

[0184] It should be noted that, for example, the attached document... Figure 21 As shown, the consumable corresponding to the first consumable category information is H consumable, the consumable corresponding to the second consumable category information is I consumable, and G consumable is the other one of the two consumables in the current alignment state, that is, the original two consumables G consumable and H consumable are switched to H consumable and I consumable.

[0185] It should be noted that when a consumable is removed from a set of consumable channels in the second position, the set of consumable channels switches from the second position to the first position. That is, when there is no consumable in a set of consumable channels in the second position, the set of consumable channels automatically switches from the second position to the first position. For example, the initial position of the set of consumable channels is the first position. When it switches to the second position, a consumable is introduced. When the consumable is removed from the set of consumable channels in the second position, the set of consumable channels switches from the second position to the first position.

[0186] In one optional embodiment of the present invention, when all a group of consumable channels are in the first position, the consumable switching device is in the initial state.

[0187] In practical applications, in the initial state, all consumable channels of the consumable input device are aligned with some consumable channels of the consumable switching device, and the consumables in the consumable channels of the consumable input device can be imported into the consumable channels of the consumable switching device. Through the classification and switching of the above three states A, B, and C, high-efficiency switching coverage of all states of multiple colors in the printing process is achieved, thereby improving printing efficiency.

[0188] In one optional embodiment of the present invention, the consumable input device includes at least two sets of input channels corresponding to at least two sets of movable consumable channels, and each set of input channels includes at least one linear channel.

[0189] In practical applications, a set of input channels is set up to correspond to a set of consumable channels.

[0190] In one optional embodiment of the present invention, a set of movable consumable channels includes at least one dual-channel unit, the dual-channel unit including two consumable channels, the consumable channels being able to import and export printing consumables; for example, the dual-channel unit includes a linear channel and a reversing channel, which can export the imported consumables to the corresponding print head of the 3D printer.

[0191] In one optional embodiment of the present invention, the consumable input device includes at least two sets of horizontally parallel input channels, one set of input channels including two vertically parallel straight channels; at least two sets of movable consumable channels are arranged horizontally, one set of movable consumable channels including at least one vertically parallel straight double channel and one vertically parallel cross double channel. By setting one set of movable consumable channels corresponding to the input channels, the consumables in the input channels can be guided to the corresponding print head of the 3D printer through at least two sets of movable consumable channels.

[0192] In the initial state, at least two sets of input channels are configured to correspond to a through dual channel, or at least two sets of input channels are configured to correspond to a cross dual channel.

[0193] In one optional embodiment of the present invention, the printing consumable category information includes at least consumable color information and / or consumable material information.

[0194] In practical applications, when the printing consumable category information includes consumable color information, consumables of different colors can be imported into the corresponding position or the corresponding print head of the 3D printer; when the printing consumable category information includes consumable material information, consumables of different materials can be imported into the corresponding position or the corresponding print head of the 3D printer.

[0195] An optional embodiment of the present invention provides a specific embodiment of a 3D printing consumable switching method, applied to a consumable switching device, wherein the consumable switching device receives consumables transmitted by a consumable input device.

[0196] Obtain printing information, which should include at least the type of printing consumables.

[0197] In response to a change in printing consumable category information from first consumable category information to second consumable category information, based on the position of the second consumable corresponding to the second consumable category information in the consumable input device and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to a second alignment state with the consumable input device. The second alignment state is used to guide the consumable corresponding to the second consumable category information in the consumable input device to the 3D printer.

[0198] The alignment state is when the filament switching device simultaneously outputs at least two types of filaments to the 3D printer.

[0199] It should be noted that in the field of 3D printing, 3D printers print based on the information of the printing model, which may include information such as the model's structure, color, and consumable material. In this application, the consumable category information includes consumable color information, consumable material information, consumable production information, and other information related to consumable attributes. 3D printers can select the corresponding consumable for printing based on this consumable category information of color or material.

[0200] The alignment state includes the current alignment state and the second alignment state. It can be understood that the alignment state is when the consumable switching device receives the consumable transmitted by the consumable input device and conducts the received consumable to the 3D printer. Among them, the printing consumable category information changes from the first consumable category information to the second consumable category information. Specifically, the printing consumable can be switched from the consumable corresponding to the first consumable category information to the consumable corresponding to the second consumable category information. That is, the 3D printer needs to switch from the current printing consumable to the next printing consumable.

[0201] Based on the position of the consumable corresponding to the second consumable category information in the consumable input device and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to the second alignment state with the consumable input device. This can be understood as the need to switch one of the two consumables in the consumable switching device to the other and output it to the corresponding position on the 3D printer. This requires switching based on the current alignment state between the consumable switching device and the consumable input device so that the two consumables can be correctly output to the corresponding positions on the 3D printer.

[0202] In practical applications, such as 3D printers that output two types of consumables simultaneously, the 3D printer has two printheads or sprue structures that receive the two types of consumables respectively, with each type of consumable entering a printhead to prepare for or print.

[0203] It should be noted that the consumable input device can refer to a device that provides printing consumables to the consumable switching device. The consumables in the consumable input device can be consumables fed into the consumable input device by a device with feeding power, such as a feeding hopper. The consumables can be powered by a feeding hopper to be fed into the consumable switching device. The consumable input device only provides the function of guiding consumables into the consumable switching device. Alternatively, the consumables can be powered by the consumable input device to be fed into the consumable switching device. In short, the function of the consumable input device is to provide printing consumables to the consumable switching device.

[0204] Optionally, the consumable switching device includes at least two sets of movable consumable channels, one set of consumable channels including a first position and a second position, and the alignment state includes at most two sets of consumable channels being in the second position;

[0206] The drive structure 6 drives a set of consumable channels 100 to switch between the first and second positions, so that different consumables can be guided to different 3D printing heads through the consumable switching device. Here, the first and second positions are not particularly limited and can be two positions of a set of consumable channels when moving in a straight line.

[0207] For example, a set of consumable channels 100 includes a vertically parallel straight channel and a reversing channel.

[0214] Optionally, the entrance and exit ends of the reversing channel are located on different sides, for example, see reference. Figure 7 The reversing channel is a horizontally placed channel, with its entrance end located on the upper side of one end of the reversing channel and its exit end located on the lower side of the other end of the reversing channel; that is, different sides means that the entrance end and the exit end are located on the upper side and the lower side respectively.

[0215] Optionally, a set of consumable channels 100 includes two dual-channel units; the dual-channel unit can be one of a straight-through dual-channel 1, a cross-channel 2, or a hybrid dual-channel. When a set of consumable channels 100 includes a straight-through dual-channel 1 and a cross-channel 2, the position of the set of consumable channels 100 can be adjusted to guide the two consumables entering the set of consumable channels 100 directly to the two printheads through the straight-through dual-channel 1, or to guide the two consumables entering the set of consumable channels to the two printheads through the cross-channel consumable reversal; thereby achieving the switching of consumable guidance by adjusting the position of the set of consumable channels.

[0220] Optionally, a set of consumable channels 100 includes a straight-through dual channel 1 and a cross dual channel 2 arranged side by side on the same straight line. In practical applications, the straight-through dual channel 1 and the cross dual channel 2 can be arranged side by side in the horizontal direction, or in the vertical direction, or in other forms on the same straight line. In an optional embodiment of the present invention, the consumable switching device 10 includes at least two sets of consumable channels in movable positions arranged side by side in the horizontal direction. One set of consumable channels 100 includes a straight-through dual channel 1 and a cross dual channel 2 arranged side by side in the vertical direction.

[0227] Optionally, the consumable switching device includes at least two sets of movable consumable channels. Each set of consumable channels has a first position and a second position. The current alignment state includes at most two sets of consumable channels being in the second position, and includes position A, position B, and position C. Position A occurs when at least two sets of consumable channels are both in the first position, for example, when at least two sets of movable consumable channels are both in the initial state. Position B occurs when one set of the at least two sets of movable consumable channels is in the second position, for example, when one set of the at least two sets of movable consumable channels switches from the first position to the second position, while the remaining sets of consumable channels remain in the first position. Position C occurs when two sets of the at least two sets of movable consumable channels are in the second position, for example, when two sets of the at least two sets of movable consumable channels switch from the first position to the second position, while the remaining sets of consumable channels remain in the first position.

[0228] As an example, the consumable input device includes at least two sets of horizontally parallel input channels, and one set of input channels includes two vertically parallel channels; the first consumable corresponding to the first consumable category information is located in the set of consumable channels in the second position;

[0229] The consumable switching device 10 includes at least two sets of consumable channels arranged side-by-side in the horizontal direction and movable in position. One set of consumable channels 100 includes a vertically parallel straight-through dual channel 1 and a cross dual channel 2. The consumable channel 100 is connected to the drive structure 6, which is used to drive the consumable channel 100 to switch between a first position and a second position. The straight-through dual channel 1 includes two vertically parallel straight channels. The straight-through dual channel 1 is used to guide consumables through the straight-through dual channel 1 in the same direction. The cross dual channel 2 includes two vertically parallel reversing channels. The cross dual channel 2 is used to guide consumables to enter from the channel above the inlet end of the cross dual channel 2 and exit from the channel below the outlet end of the cross dual channel 2. The cross dual channel 2 is used to guide consumables to enter from the channel below the inlet end of the cross dual channel 2 and exit from the channel above the outlet end of the cross dual channel 2.

[0230] The consumable output structure 20 includes a first output channel 4 and a second output channel 5, which are respectively connected to the output end of the consumable switching device 10. The first output channel 4 is used to guide the consumable output by the consumable switching device 10 to the first print head, and the second output channel 5 is used to guide the consumable output by the consumable switching device 10 to the second print head.

[0231] The consumable export structure 20 is set to correspond to the outlet end of at least two sets of consumable channels through the dual-channel 1. The first export channel 4 is set to correspond to the upper channel of the outlet end of the dual-channel 1, and the second export channel 5 is set to correspond to the lower channel of the outlet end of the dual-channel 1.

[0232] The consumable input device 30 includes at least two sets of consumable input channels arranged side by side on the same straight line, and the consumable input device 30 is set corresponding to the inlet end of the direct dual channel 1.

[0233] The consumable input device includes at least two sets of horizontally parallel input channels, and one set of input channels includes two vertically parallel input channels; the first consumable corresponding to the first consumable category information is located in the consumable channel in the second position;

[0234] When the current alignment state is position A.

[0235] Based on the position of the second consumable corresponding to the second consumable category information in the consumable input device, and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to the second alignment state with the consumable input device, specifically including:

[0236] When the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are both located in the upper input channel of the consumable input device or both located in the lower input channel of the consumable input device, the consumable channel corresponding to a set of movable positions of the second consumable category information is controlled to switch from the first position to the second position.

[0237] It should be noted that, for example, the attached document... Figure 9 and attached Figure 4 As shown, the consumables are guided from the consumable input device, consumable switching device, and consumable export structure to the corresponding print head of the 3D printer. The consumable switching device receives the consumables from the consumable input device. Based on the position of the second consumable corresponding to the second consumable category information in the consumable input device, and the current alignment state between the consumable switching device and the consumable input device, the consumable switching device is switched to a second alignment state with the consumable input device. The second alignment state is used to guide the consumables corresponding to the second consumable category information in the consumable input device into the consumable export structure, and then transported to the print head of the 3D printer. The consumables corresponding to the first consumable category information are consumables B, the consumables corresponding to the second consumable category information are consumables C, and consumables A are the other one of the two consumables in the current alignment state, that is, the original two consumables A and B are switched to consumables B and C.

[0238] When the first consumable position corresponding to the first consumable category information and the second consumable position corresponding to the second consumable category information are respectively located in the upper input channel and the lower input channel of the consumable input device, the A position state is maintained as the second alignment state.

[0239] It should be noted that, for example, the attached document... Figure 14 and attached Figure 4 As shown, the consumable material is guided from the consumable material input device, consumable material switching device, and consumable material export structure to the corresponding print head of the 3D printer. The consumable material switching device receives the consumable material from the consumable material input device. Based on the position of the second consumable material corresponding to the second consumable material category information in the consumable material input device, and the current alignment state between the consumable material switching device and the consumable material input device, the consumable material switching device is switched to a second alignment state with the consumable material input device. The second alignment state is used to guide the consumable material corresponding to the second consumable material category information in the consumable material input device into the consumable material export structure, and then deliver it to the print head of the 3D printer. The consumable material corresponding to the first consumable material category information is consumable material B, the consumable material corresponding to the second consumable material category information is consumable material C, and consumable material A is the other one of the two consumable materials in the current alignment state, that is, the original two consumable materials A and B are switched to consumable materials B and C.

[0240] It should be noted that "the first consumable location corresponding to the first consumable category information and the second consumable location corresponding to the second consumable category information are located in the upper and lower channels of the consumable input device, respectively," which means...

[0241] "The first consumable location corresponding to the first consumable category information is located in one of the upper channel and the lower channel of the consumable input device; the second consumable location corresponding to the second consumable category information is located in the other of the upper channel and the lower channel of the consumable input device."

[0242] It should also be noted that when a consumable in a set of consumable channels located in the second position is removed, leaving no consumable in that set of consumable channels, the set of consumable channels switches from the second position to the first position. That is, when there is no consumable in a set of consumable channels located in the second position, the set of consumable channels automatically switches from the second position to the first position. For example, if the initial position of the set of consumable channels is the first position, when it switches to the second position, a consumable is introduced, and when the consumable is removed from the set of consumable channels in the second position, the set of consumable channels switches from the second position to the first position.

[0243] This application embodiment achieves the output of the two types of consumables currently being printed and those to be printed to the corresponding print heads of the 3D printer through the consumable export structure by switching the alignment state of the consumable switching device. This enables multiple consumables to be input to the two print heads of the 3D printer separately through the consumable switching device. Only one set of consumables of different colors and the consumable switching device are needed. The consumable switching device can deliver this set of consumables of different colors to the corresponding print heads of the 3D printer, thereby improving the utilization rate of consumables and the device.

[0244] As shown in the figure, Embodiment 3 of this application provides a 3D printing consumable switching system, including a consumable switching device and a consumable input device for inputting consumables.

The 3D printing consumable switching device further includes:

[0245] The information receiving unit acquires printing information, which includes at least information about the type of printing consumables.

[0246] The state switching unit responds to a change in printing consumable category information from first consumable category information to second consumable category information. Based on the position of the second consumable corresponding to the second consumable category information in the consumable input device and the current alignment state between the consumable switching device and the consumable input device, it switches the consumable switching device to a second alignment state with the consumable input device. The second alignment state is used to connect the consumable corresponding to the second consumable category information in the consumable input device to the 3D printer.
