[0051] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0052] At present, the mainstream 3D printing technologies for silicone products are material extrusion molding technology and photopolymerization curing technology. Extrusion molding technology is limited by the curing speed of silicone, resulting in low printing efficiency. Photopolymerization curing technology adds photosensitive polymers to silicone, which trigger cross-linking reactions and promote silicone curing through ultraviolet or infrared irradiation. In addition, the photosensitive polymers in photopolymerization curing technology and a series of subsequent reactions limit product applications and pose safety risks.

[0053] Therefore, the embodiment of the present application provides a silicone printing system to solve the problem in the prior art of how to promote silicone curing and improve printing efficiency while ensuring material safety. The present application also relates to a silicone printing method.

[0054] The present application is described in detail below through specific embodiments and drawings.

[0055] The present application embodiment provides a silicone printing system, as follows Figure 1 The silicone printing system is described in detail. Figure 1 It is a schematic framework diagram of a silicone printing system provided in an embodiment of the present application.

[0056] In this embodiment, the silicone printing system includes a laser printing module 10, an extrusion printing module 20 and a data processing module 30; wherein the data processing module 30 is used to obtain data information of the object to be printed, and generate first printing data and second printing data according to the data information, and send the first printing data to the extrusion printing module 20, and send the second printing data to the laser printing module 10. The extrusion printing module 20 is used to receive the first printing data, and print the silicone material in at least one base printing area of ​​the target object in an extrusion manner according to the first printing data, wherein the base printing area can constitute the base of the target object. The laser printing module 10 is used as a heat source to receive the second printing data, and heat and cure the base printing area according to the second printing data to form the target object.

[0057] In this embodiment, the silica gel material is a silica gel material containing fluoride, and the silica gel material further contains component A and component B. Of course, in other examples, the silica gel material may only contain silica gel components.

[0058] In this embodiment, the data processing module 30 is used to obtain data information of the object to be printed, and generate first printing data and second printing data according to the data information. Figure 2 As shown, Figure 2 1 is a flow chart of a method for generating printing data provided by an embodiment of the present application. Generating first printing data and second printing data according to the data information includes the following steps:

[0059] Step S201: Analyze and model the data information of the object to be printed to obtain 3D shape data of the object to be printed.

[0060] In this step, the object to be printed includes a silicone object to be printed, that is, the object is made of silicone material. Each object to be printed has its own morphological structure. In this regard, the data information of the object to be printed can be analyzed to obtain morphological feature data corresponding to the object to be printed. Morphological feature data refers to the shape structure of the object to be printed and the corresponding coordinate position of each shape structure in three-dimensional space. The morphological feature data can fully reflect the three-dimensional morphological structure of the object to be printed. Specifically, in one example, the data information of the object to be printed includes image data of the object to be printed, and the image data of the object to be printed can be subjected to image recognition analysis to obtain morphological feature data corresponding to the object to be printed. In another example, the object to be printed can be directly physically scanned to obtain scan data, and the scan data has a one-to-one correspondence with the physical data of the object to be printed, and then the obtained scan data can be converted into morphological feature data of the object to be printed.

[0061] Then, the morphological feature data is processed by data model to obtain standard model data associated with the object to be printed. In this step, the data model processing of the morphological feature data mainly adopts a linear normalization processing method so that the morphological feature data can reach the standard model data that can be processed by the preset model.

[0062] Finally, a preset model is obtained, and the standard model data is input into the preset model to obtain 3D morphological data for the object to be printed. Specifically, in this step, the preset model is obtained by pre-training, that is, the standard model data of the above-mentioned morphological feature data is obtained, and the standard model data is used as a sample for training, which can be called a standard model data sample. An initial model is constructed, the parameters of the initial model are set, and the standard model data sample is input into the initial model. The initial model is iteratively trained with a large number of standard model data samples, and the output result of the initial model is compared with the preset standard 3D morphological data. If the comparison result is consistent, the initial model is determined as the preset model; if the comparison result is inconsistent, the standard model data sample is continuously input into the initial model for iterative training until the output result is consistent with the preset standard 3D morphological data. Then, after obtaining the preset model, the standard model data is input into the preset model to obtain the 3D morphological data for the object to be printed.

[0063] Step S202: Acquire region information of several regions of the 3D morphological data of the object to be printed.

[0064] After obtaining the 3D morphological data for the object to be printed, the regional information of several regions of the 3D morphological data for the object to be printed is obtained. Specifically, first, the regional demarcation line for regional division is determined according to the 3D morphological data of the object to be printed. The 3D morphological data of each object to be printed can reflect the three-dimensional form of the real object to be printed. The object to be printed contains multiple parts, so that the object to be printed can be divided according to each part, and then the object to be printed can be divided into multiple regions. Of course, in other examples, the object to be printed can also be divided layer by layer along a certain direction to divide the object to be printed into a multi-layer structure. Then, the spatial coordinate information corresponding to the regional demarcation line is obtained. In the three-dimensional space, each structural part has a corresponding spatial coordinate. Based on this embodiment, it is necessary to divide the object to be printed into regions, so it is necessary to obtain the spatial coordinate information corresponding to the regional demarcation line. In an example, considering that the object to be printed can be divided into multiple regions, the regional demarcation lines between each adjacent region can overlap, and this example only needs to obtain the regional demarcation line of one of the regions. Then, the regional demarcation line of the adjacent region can be determined according to the spatial coordinate information corresponding to the regional demarcation line. Finally, the regional information of each area is determined according to the regional boundary lines of adjacent areas.

[0065] Step S203: generating first printing data and second printing data according to the area information of a plurality of areas.

[0066] After obtaining the area information of several areas, the first printing data and the second printing data are generated according to the area information of the several areas. Specifically, first, each area is encoded to form a coding area with coding information. The object to be printed is divided into multiple areas, and each area is encoded in order to clarify the subsequent printing order of each area. According to the coding information of the coding area, the printing area that can be spliced ​​and printed in sequence is constructed. For example, coding area No. 1, coding area No. 2, coding area No. 3, etc., so that the printing area 1, printing area 2 and printing area 3 that can be spliced ​​and printed in sequence are constructed according to the coding information of the coding area. Then, the base information of each printing area is obtained, and the base information of each printing area is used as the first printing data; the base information of each printing area at least includes the spatial coordinate information of the printing area, and the base of the printing area refers to the basic surface of the printing area, and the printing area is formed by the basic surface. In one example, the basic surface of the printing area can be understood as the horizontal end surface or curved surface of the printing area. Then, the morphological information of each printing area is determined according to the 3D morphological data of the object to be printed, and the morphological information of each printing area is used as the second printing data. In this example, each printing area has its own form, so the form information of each printing area can be used as the second printing data.

[0067] In this embodiment, the first printing data is generally formed first, and then the second printing data is formed. That is, the substrate of each printing area is first shaped, and then the corresponding shape is shaped on the substrate. In this regard, in this embodiment, the first printing data and the second printing data are generated according to the area information of a plurality of areas, and further includes: determining the first printing data as a first printing order and determining the second printing data as a second printing order, wherein the first printing order is before the second printing order.

[0068] In this embodiment, since the laser can generate high energy, the temperature of the laser may change during the continuous printing process, thus affecting the printing result. In this regard, the data processing module 30 is also used to obtain the temperature information of the substrate printing area and the temperature information of the laser of the laser printing module 10, and generate corresponding second printing data according to the temperature information of the substrate printing area and the temperature information of the laser of the laser printing module 10.

[0069] Specifically, first, the substrate temperature information of the next substrate printing area and the temperature information of the laser printing module 10 for the current substrate printing area are obtained. The substrate temperature of each substrate printing area will basically not change, but the temperature of the laser may change, and then it is necessary to determine the temperature information of the laser of the laser printing module 10 for the current substrate printing area. Then, according to the substrate temperature information of the next substrate printing area and the temperature information of the laser of the laser printing module 10 for the current substrate printing area, the printing power information and preheating temperature information of the laser of the laser printing module 10 for the next substrate printing area are obtained. Finally, the corresponding second printing data is generated according to the printing power information and preheating temperature information of the laser.

[0070] After obtaining the first printing data and the second printing data, the first printing data is sent to the extrusion printing module 20, and the second printing data is sent to the laser printing module 10. The extrusion printing module 20 further processes the first printing data, and the laser printing module 10 further processes the second printing data.

[0071] The extrusion printing module 20 is used to receive the first printing data and print the silicone material in at least one base printing area of ​​the target object in an extrusion manner according to the first printing data. The base printing area can constitute the base of the target object.

[0072] Specifically, the first base point printing position is determined. When printing the substrate printing area, the base point printing position for the substrate printing area needs to be determined. The base point printing position is a reference point for printing the substrate printing area. Then, the silicone material is printed out of the initial substrate printing area of ​​the target object in an extrusion manner according to the first base point printing position and the first printing data. The initial substrate printing area is the first substrate printing area of ​​the target object. In this step, the first printing data includes initial substrate printing area information with coding information and spatial coordinate information corresponding to the initial substrate printing area. On the basis of determining the first base point printing position, the initial substrate printing area is printed out in an extrusion manner according to the initial substrate printing area information with coding information and the spatial coordinate information corresponding to the initial substrate printing area. Then, the spatial coordinate information of each remaining substrate printing area and the first printing order of each remaining substrate printing area are determined according to the first printing data. For example, assume that the target object has five substrate printing areas, including initial substrate printing area No. 1, substrate printing area No. 2, substrate printing area No. 3, substrate printing area No. 4, and final substrate printing area No. 5. The substrate printing areas No. 2 to 5 are the remaining substrate printing areas, and the substrate printing areas No. 1 to 5 have their own spatial coordinate information, and the substrate printing areas No. 1 to 5 can be printed according to the first printing sequence (positive printing sequence). Finally, the remaining multiple substrate printing areas are printed according to the spatial coordinate information of each substrate printing area and the first printing sequence. That is, after printing the initial substrate printing area No. 1, the substrate printing area No. 2 is printed, and then the substrate printing area No. 3 is printed, and then the substrate printing area No. 4 and the final substrate printing area No. 5 are printed.

[0073] In this embodiment, after the extrusion printing module 20 prints the silicone material in the substrate printing area of ​​the target object in an extrusion manner according to the first printing data, the laser printing module 10 heats and cures the substrate printing area according to the second printing data to form the target object. In one example, the laser printing module 10 serves as a heat source, and the laser printing module 10 includes at least one laser and at least one driving mechanism, and the laser is connected to the driving mechanism to drive the laser to move to a specified position under the drive of the driving mechanism to heat and cure the substrate printing area. The laser printing module 10 receives the second printing data, and heats and cures the substrate printing area according to the second printing data to form the target object.

[0074] Specifically, first, the second base point printing position is determined in each substrate printing area. After the extrusion printing module 20 prints the silicone material in each substrate printing area of ​​the target object in an extrusion manner according to the first printing data, the laser printing module 10 heats and cures each substrate printing area according to the second printing data to form the target object. When heating and curing each substrate printing area, it is necessary to determine the second base point printing position in each substrate printing area, so as to heat and cure the substrate printing area with the second base point printing position as the starting point. Then, the second printing order of the laser printing module 10 relative to each substrate printing area is determined according to the first printing order of each substrate printing area. In this step, in order to facilitate the timely heating and curing of each substrate printing area printed by the extrusion printing module 20, the printing order of the laser printing module 10 for heating and curing each substrate printing area corresponds to the printing order of each substrate printing area printed by the extrusion printing module 20. For example, the initial substrate printing area No. 1, the substrate printing area No. 2, the substrate printing area No. 3, the substrate printing area No. 4 and the final substrate printing area No. 5 have a positive printing order from 1 to 5. Then, during heating and curing, the initial substrate printing area No. 1 is heated and cured first, and then the substrate printing area No. 2 is heated and cured, and then the substrate printing area No. 3 is heated and cured, and then the substrate printing area No. 4 and the final substrate printing area No. 5 are heated and cured.

[0075] In this embodiment, the heat curing requires the morphological information of the substrate printing area, that is, the morphological information for each substrate printing area is obtained according to the second printing data. After determining the second printing sequence of each substrate printing area and the morphological information of each substrate printing area, the substrate printing areas are heated and cured one by one according to the second printing sequence of each substrate printing area, the second base point printing position of each substrate printing area and the corresponding morphological information to form a target object.

[0076] In the present embodiment, it should be noted that after the extrusion printing module 20 prints the first base printing area of ​​the target object with the silicone material in an extrusion manner, the laser printing module 10 heats and cures the first base printing area; at the same time, the extrusion printing module 20 continues to print the second base printing area of ​​the target object with the silicone material in an extrusion manner, and the laser printing module 10 heats and cures the second base printing area; and so on, to achieve a printing method of printing by extrusion and heating at the same time.

[0077] The embodiment of the present application provides a silicone printing system, including: a laser printing module 10, an extrusion printing module 20 and a data processing module 30; wherein the data processing module 30 is used to obtain data information of an object to be printed, and generate first printing data and second printing data according to the data information, and send the first printing data to the extrusion printing module 20, and send the second printing data to the laser printing module 10; the extrusion printing module 20 is used to receive the first printing data, and print the silicone material in at least one base printing area of ​​the target object in an extrusion manner according to the first printing data; the base printing area can constitute the base of the target object; the laser printing module 10 is used as a heat source to receive the second printing data, and heat and cure the base printing area according to the second printing data to form the target object.

[0078] In the embodiment of the present application, the data processing module 30 generates first printing data for the extrusion printing module 20 and second printing data for the laser printing module 10 according to the data information of the object to be printed. The extrusion printing module 20 prints the silicone material in at least one base printing area of ​​the target object in an extrusion manner according to the first printing data, so that the silicone material can meet the printing requirements while avoiding silicone waste. The laser printing module 10 heats and cures the base printing area according to the second printing data to form the target object. The laser source of the laser printing module 10 improves the curing, and dynamically optimizes and adjusts the light source and the material extrusion amount to improve the accuracy and efficiency, so as to realize the printing method of printing in an extrusion manner while heating and curing. The laser is used as an energy source to promote the curing of silicone without destroying the safety of silicone.

[0079] The embodiment of the present application also provides a silicone printing method, which is applied to the silicone printing system described above, wherein the laser printing module 10 in the silicone printing system serves as a heat source, and the extrusion printing module 20 prints the silicone material in an extrusion manner. Figure 3 : is a flow chart of a silicone printing method provided in an embodiment of the present application. The method comprises the following steps:

[0080] Step S301: Control the data processing module to obtain data information of the object to be printed, and generate first printing data and second printing data according to the data information, and send the first printing data to the extrusion printing module and send the second printing data to the laser printing module.

[0081] The specific steps of generating the first printing data and the second printing data according to the data information refer to the description of the above embodiment, which will not be repeated here.

[0082] Step S302: Control the extrusion printing module to receive the first printing data, and print the silicone material in at least one base printing area of ​​the target object in an extrusion manner according to the first printing data; the base printing area can constitute the base of the target object.

[0083] Specifically, the first base point printing position is determined. When printing the substrate printing area, the base point printing position for the substrate printing area needs to be determined. The base point printing position is a reference point for printing the substrate printing area. Then, the silicone material is printed out of the initial substrate printing area of ​​the target object in an extrusion manner according to the first base point printing position and the first printing data. The initial substrate printing area is the first substrate printing area of ​​the target object. In this step, the first printing data includes initial substrate printing area information with coding information and spatial coordinate information corresponding to the initial substrate printing area. On the basis of determining the first base point printing position, the initial substrate printing area is printed out in an extrusion manner according to the initial substrate printing area information with coding information and the spatial coordinate information corresponding to the initial substrate printing area. Then, the spatial coordinate information of each remaining substrate printing area and the first printing order of each remaining substrate printing area are determined according to the first printing data. For example, assume that the target object has five substrate printing areas, including initial substrate printing area No. 1, substrate printing area No. 2, substrate printing area No. 3, substrate printing area No. 4, and final substrate printing area No. 5. The substrate printing areas No. 2 to 5 are the remaining substrate printing areas, and the substrate printing areas No. 1 to 5 have their own spatial coordinate information, and the substrate printing areas No. 1 to 5 can be printed according to the first printing sequence (positive printing sequence). Finally, the remaining multiple substrate printing areas are printed according to the spatial coordinate information of each substrate printing area and the first printing sequence. That is, after printing the initial substrate printing area No. 1, the substrate printing area No. 2 is printed, and then the substrate printing area No. 3 is printed, and then the substrate printing area No. 4 and the final substrate printing area No. 5 are printed.

[0084] Step S303: controlling the laser printing module to receive the second printing data, and heating and curing the printing area of ​​the substrate according to the second printing data to form a target object.

[0085] In this embodiment, after the extrusion printing module prints the silicone material in the base printing area of ​​the target object in an extrusion manner according to the first printing data, the laser printing module heats and cures the base printing area according to the second printing data to form the target object. In one example, the laser printing module serves as a heat source, and the laser printing module includes at least one laser and at least one driving mechanism, and the laser is connected to the driving mechanism to drive the laser to move to a specified position under the drive of the driving mechanism to heat and cure the base printing area. The laser printing module receives the second printing data, and heats and cures the base printing area according to the second printing data to form the target object.

[0086] Specifically, first, the second base point printing position is determined in each substrate printing area. After the extrusion printing module prints the silicone material in an extrusion manner according to the first printing data to form each substrate printing area of ​​the target object, the laser printing module heats and cures each substrate printing area according to the second printing data to form the target object. When heating and curing each substrate printing area, it is necessary to determine the second base point printing position in each substrate printing area, so as to heat and cure the substrate printing area with the second base point printing position as the starting point. Then, the second printing order of the laser printing module relative to each substrate printing area is determined according to the first printing order of each substrate printing area. In this step, in order to facilitate the timely heating and curing of each substrate printing area printed by the extrusion printing module, the printing order of the laser printing module for heating and curing each substrate printing area corresponds to the printing order of each substrate printing area printed by the extrusion printing module. For example, the initial substrate printing area No. 1, the substrate printing area No. 2, the substrate printing area No. 3, the substrate printing area No. 4 and the final substrate printing area No. 5 have a positive printing order from 1 to 5. Then, during heating and curing, the initial substrate printing area No. 1 is heated and cured first, and then the substrate printing area No. 2 is heated and cured, and then the substrate printing area No. 3 is heated and cured, and then the substrate printing area No. 4 and the final substrate printing area No. 5 are heated and cured.

[0087] In this embodiment, the heat curing requires the morphological information of the substrate printing area, that is, the morphological information for each substrate printing area is obtained according to the second printing data. After determining the second printing sequence of each substrate printing area and the morphological information of each substrate printing area, the substrate printing areas are heated and cured one by one according to the second printing sequence of each substrate printing area, the second base point printing position of each substrate printing area and the corresponding morphological information to form a target object.

[0088] In the present embodiment, it should be noted that after the extrusion printing module prints the first base printing area of ​​the target object with the silicone material in an extrusion manner, the laser printing module heats and cures the first base printing area; at the same time, the extrusion printing module continues to print the second base printing area of ​​the target object with the silicone material in an extrusion manner, and the laser printing module heats and cures the second base printing area; and so on, to achieve a printing method of printing by extrusion and heating at the same time.

[0089] In the embodiment of the present application, a data processing module generates first printing data for an extrusion printing module and second printing data for a laser printing module according to data information of an object to be printed. The extrusion printing module prints the silicone material in at least one base printing area of ​​the target object in an extrusion manner according to the first printing data, so that the silicone material can meet the printing requirements while avoiding silicone waste. The laser printing module heats and cures the base printing area according to the second printing data to form the target object. The laser source of the laser printing module improves curing, and dynamically optimizes and adjusts the light source and the amount of material extrusion to improve accuracy and efficiency, so as to realize a printing method of printing in an extrusion manner while heating and curing. Laser serves as an energy source to promote the curing of silicone without destroying the safety of silicone.
