The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0085] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0086] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0087] See Figure 1 and Figure 2 This embodiment provides an additive manufacturing apparatus 100. The additive manufacturing apparatus 100 can be a photopolymerization additive manufacturing apparatus or a fused deposition modeling additive manufacturing apparatus. The additive manufacturing apparatus 100 includes a housing assembly 90 and a target part. The target part is mounted within the housing assembly 90. The target part includes a Z-axis drive 30 and a power supply assembly 994. The power supply assembly 994 is electrically connected to the Z-axis drive 30 to provide transmission power to the Z-axis drive 30. The additive manufacturing apparatus 100 also includes a tray assembly 40 and a platform assembly 10. The platform assembly 10 is connected to the Z-axis drive 30. The tray assembly 40 is connected to the Z-axis drive 30. The Z-axis drive 30 is configured to drive the tray assembly 40 and the platform assembly 10 to move relative to each other. The tray assembly 40 is used to contain resin consumables and to form a workpiece on the platform assembly 10.

[0088] Please see Figure 1 and Figure 2 The housing assembly 90 is used in the additive manufacturing equipment 100. The housing assembly 90 includes a housing 91 and a first display 991. The housing 91 includes a rear wall 911 and a first top wall 912. The rear wall 911 is used to mount a target component. The first top wall 912 is connected to the rear wall 911 and extends along a first direction X. The first display 991 is connected to one end of the first top wall 912 opposite to the rear wall 911 along the first direction X.

[0089] According to the housing assembly 90 of this embodiment, the first display 991 and the target component can balance the center of gravity of the housing assembly 90 in the first direction X, making the housing assembly 90 stable and reliable in placement and reducing the possibility of the housing assembly 90 tilting and tipping over during operation. In addition, the first display 991 is mounted on the first top wall 912, which conforms to ergonomic design and improves the user's ease of operation.

[0090] In some embodiments, see Figure 2 The first display element 991 has a display surface P6, which is inclined downward along a second direction Z in a direction opposite to the rear wall 911 in the first direction X. The second direction Z intersects the first direction X. Thus, when the user uses the additive manufacturing equipment 100, the display surface P6 is approximately perpendicular to the user's line of sight, making it easier for the user to directly observe the displayed information on the display surface P6 and to operate the equipment, thereby further improving the user experience.

[0091] In some embodiments, the first display element 991 is configured as a display screen. The display surface P6 can display an operation interface for the additive manufacturing equipment 100 during the manufacturing process and can be operated by the user by touching it.

[0092] In some embodiments, see Figure 3 The housing assembly 90 also includes a second display 992, which is located on the side of the first top wall 912 opposite to the display surface P6. The second display 992 is configured to display the manufacturing status of the additive manufacturing equipment 100. In this way, various parameters in the additive manufacturing process can be displayed in different ways, allowing users to quickly and intuitively understand the manufacturing status or progress, thus improving the user experience.

[0093] Specifically, the second display element 992 can be configured as a status indicator light, which can display additive manufacturing parameters such as the manufacturing status of the additive manufacturing equipment 100 or the remaining manufacturing time. The light emitted by the status indicator light can pass through the first top wall 912 for easy observation by the user. In this embodiment, the status indicator light can be configured as two figure-eight shaped indicator lights to display different letters and Arabic numerals. In other embodiments, the status indicator light can also be disposed on the side of the first top wall 912 where the display surface P6 is provided.

[0094] In some embodiments, see Figure 3 The first top wall 912 has a mounting groove C1 on the side opposite to the display surface P6. The housing assembly 90 also includes a control assembly 993, which is installed in the mounting groove C1. This improves the protection of the control assembly 993. The control assembly 993 can be configured as a control board. The control assembly 993 is configured to be electrically connected to the power supply assembly 994, the tray assembly 40, etc., and to the first display element 991 and the second display element 992 to realize user control operation. The second display element 992 is also housed in the mounting groove C1 so that the light emitted by the second display element 992 can be accurately transmitted, improving the user's viewing experience.

[0095] In some implementations, see Figure 4 The first top wall 912 includes a wall body 9121, a first surrounding wall 9124, a first wall segment 9122, and a second wall segment 9123. The wall body 9121 is connected to the rear wall 911. The first surrounding wall 9124 is connected to the wall body 9121 and protrudes relative to the wall body 9121 along a second direction Z. The first wall segment 9122 and the second wall segment 9123 are connected to the first surrounding wall 9124. A mounting groove C1 is defined between the first surrounding wall 9124, the first wall segment 9122, and the second wall segment 9123.

[0096] In some implementations, see Figure 4 The second wall section 9123 is provided with a connector slot C3, which is used to connect to a data transmission device to transmit the manufacturing data required for additive manufacturing to the control component 993. The connector slot C3 can be configured as a slot in various forms, such as a USB slot.

[0097] In some implementations, see Figure 3 and Figure 4 A first wall segment 9122 is connected to the wall body 9121 and extends along a first direction X. A second display element 992 is mounted on the first wall segment 9122. A second wall segment 9123 is connected to the side of the first wall segment 9122 facing away from the rear wall 911. The second wall segment 9123 is inclined downwards along the direction facing away from the rear wall 911, and the first display element 991 is mounted on the second wall segment 9123. This allows the first display element 991 to be mounted in an inclined state, tilted from the display surface P6. The first wall segment 9122 extending along the first direction X allows the second display element 992 to be placed horizontally. In other embodiments, the extension direction of the first wall segment 9122 can be adjusted according to actual needs to adjust the placement state of the second display element 992.

[0098] In some implementations, see Figure 4The second wall section 9123 has a mounting hole K7. The first display 991 is mounted in the mounting hole K7 and covers the mounting hole K7 so that the first display 991 can be electrically connected to the control component 993.

[0099] In some embodiments, see Figure 5 The first top wall 912 has a first fixing hole K61 extending along the second direction Z at one end opposite to the first display element 991 in the first direction X. The Z-axis transmission device 30 has a second fixing hole K62 corresponding to the first fixing hole K61 in the second direction Z. The first fixing hole K61 and the second fixing hole K62 are connected by fastening structures such as screws and pins to ensure reliable connection between the Z-axis transmission device 30 and the first top wall 912.

[0100] In some embodiments, see Figure 4 and Figure 5 The housing also includes a bottom 93. A first top wall 912 is connected to one end of the rear wall 911 along the second direction Z. The bottom 93 is connected to the other end of the rear wall 911 along the second direction Z. The bottom 93 and the first top wall 912 are positioned opposite each other along the second direction Z.

[0101] In some implementations, see Figure 4 The bottom 93 includes a bottom wall 931, a second enclosure wall 932, and a partition wall 933. The second enclosure wall 932 is connected to the edge of the bottom wall 931 and forms a receiving groove C2 with the bottom wall 931. The rear wall 911 is connected to the second enclosure wall 932 by means of snap-fit ​​connection or the like. The rear wall 911 is connected to the bottom wall 931. The partition wall 933 is connected to the side of the bottom wall 931 along the first direction X near the rear wall 911. The partition wall 933 divides the receiving groove C2 into a first groove C21 and a second groove C22. The first groove C21 and the second groove C22 are distributed along the first direction X. The first groove C21 corresponds to the partition wall 933 along the second direction Z. The second groove C22 corresponds to the material trough assembly along the second direction Z. The second groove C22 can receive resin consumables overflowing from the material trough assembly. By separating the first tank C21 and the second tank C22, it can be ensured that consumables will not contaminate the Z-axis transmission device 30 or the power supply component 994 during the additive manufacturing process, thus ensuring the safety of the additive manufacturing equipment 100.

[0102] In some implementations, see Figure 4 The bottom 93 also includes support portions 934. The support portions 934 are spaced apart on the sidewalls 923 of the first groove C21. The Z-axis drive device 30 is supported on multiple support portions 934 and is fixedly connected to the multiple support portions 934 by means of threaded connection or pin connection. In this way, the two ends of the Z-axis drive device 30 along the second direction Z are connected to the first top wall 912 and the bottom 93 respectively, further improving the installation stability of the Z-axis drive device 30.

[0103] In some implementations, see Figure 4 and Figure 5 The housing 91 also includes two side walls 913. The two side walls 913 are respectively connected to both sides of the rear wall 911 along the third direction Y, and extend towards the first display element 991 along the first direction X. The two side walls 913 and the rear wall 911 form a receiving groove C5, within which the Z-axis drive device 30 is housed. A power supply assembly 994 is installed between the Z-axis drive device 30 and the rear wall 911. The additive manufacturing equipment 100 also includes a platform assembly 10 and a tray assembly 40. The platform assembly 10 is fixedly connected to the upper end of the Z-axis drive device 30. The tray assembly 40 is driven along the second direction Z to the Z-axis drive device 30.

[0104] In some implementations, see Figure 6 A heat dissipation hole K4 is provided on the rear wall 911, and the heat dissipation hole K4 is positioned opposite to the power supply assembly 994 along the first direction X. Thus, the heat dissipation hole K4 can dissipate heat from the rear wall 911 and the power supply assembly 994, extending the lifespan of both. The heat dissipation hole K4 is connected to the receiving cavity Q.

[0105] In some embodiments, see Figure 6 The rear wall 911 has an air inlet K2 and an exhaust outlet K3, which are spaced apart along the first direction X. Both the air inlet K2 and the exhaust outlet K3 are connected to the receiving cavity Q. Thus, during additive manufacturing, gas at a preset temperature can be introduced into the receiving cavity Q through the air inlet K2 to quickly bring the ambient temperature within the receiving cavity Q up to the additive manufacturing conditions. After additive manufacturing is completed, the gas in the receiving cavity Q is first discharged through the exhaust outlet K3 to prevent the gas in the receiving cavity Q from being directly released into the external environment, ensuring the safety of additive manufacturing.

[0106] In some embodiments, see Figure 7 The housing assembly 90 also includes an outer cover 92. The outer cover 92 has a clearance hole K1, through which the first display element 991 is exposed. The outer cover 92 is movably connected to the housing 91 and has an open and a closed state. When the outer cover 92 is closed, it and the housing 91 form a receiving cavity Q. When the outer cover 92 is open, the receiving cavity Q is open. Thus, during additive manufacturing, the closed outer cover 92 and the housing 91 form a closed receiving cavity Q, thereby improving the operational safety of the additive manufacturing equipment 100 and preventing undesirable gases generated during additive manufacturing from escaping into the external environment. After additive manufacturing is completed, by switching the outer cover 92 to the open state, the user can remove the formed workpiece from the platform assembly 10 within the open receiving cavity Q. The clearance hole K1 prevents the first display element 991 from being covered when the outer cover 92 is closed.

[0107] In some implementations, see Figure 7 The outer cover 92 includes a second top wall 921 and a front wall 922. One end of the second top wall 921 along the first direction X is movably connected to the rear wall 911, and the front wall 922 is connected to the other end of the second top wall 921 along the first direction X. The second top wall 921 has a clearance opening for exposing the first display element 991.

[0108] In some implementations, see Figure 7 The outer cover 92 also includes two side walls 923, which are spaced apart along the third direction Y. The two side walls 923 are respectively connected between the front wall 922 and the rear wall 911. The front wall 922, the rear wall 911, the first top wall 912 and the two side walls 923 form a receiving cavity Q, which is used to receive the target component.

[0109] Specifically, when the outer cover 92 is in the closed state, the two side walls 923 are respectively connected to the two side walls 913. The front wall 922, the two side walls 923 and the two side walls 913 are connected to the bottom 93 along the lower end of the second direction Z, thereby forming a closed receiving cavity Q.

[0110] In some embodiments, see Figure 7 The housing assembly 90 also includes a rotating member 94. One end of the rotating member 94 is rotatably connected to the rear wall 911, and the other end of the rotating member 94 is fixedly connected to the end of the second top wall 921 opposite to the front wall 922 along the first direction X. The rear wall 911 has a rotating hole K5, and the rotating member 94 passes through the rotating hole K5.

[0111] In some implementations, see Figure 7 The rotating component 94 includes a fixed section 941, a connecting section 942, and a limiting section 943. The fixed section 941 is fixedly connected to the second top wall 921. One end of the limiting section 943 is rotatably connected to the rear wall 911. The connecting section 942 passes through the rotating hole K5, and its two ends are connected to the limiting section 943 and the fixed section 941, respectively. The connecting section 942 is generally arc-shaped. When the outer cover 92 is in the open state, the limiting section 943 abuts against the edge of the rear wall 911 near the rotating hole K5 to limit the outer cover 92 to the housing 91, ensuring the overall stability of the housing assembly 90. When the outer cover 92 is in the closed state, the second top wall 921 abuts against the upper end of the rear wall 911 along the second direction Z to limit the outer cover 92 to the housing 91. In other embodiments, the rotating component 94 may also be constructed as a rotating shaft structure.

[0112] In some implementations, see Figure 7The outer cover 92 also includes an extension wall 924, which is connected to the side of the second top wall 921 opposite to the front wall 922 along the first direction X and extends along the second direction Z. The second top wall 921 is connected to the fixed section 941 of the rotating member 94 through the extension wall 924.
