Description

Technical Field

[0001] This application relates to the field of 3D printing technology, specifically to a method, apparatus, equipment, and storage medium for model-supported replication and transfer. Background Technology

[0002] 3D printing technology is a new type of rapid prototyping technology based on digital models. It manufactures models by printing layer by layer, which is completely different from traditional mold production. Currently, in existing photopolymer 3D printing technologies, the common practice is to first preprocess the 3D model, composed of triangular meshes generated by industrial design software such as SOLIDWORKS, using 3D preprocessing software. Then, photopolymer 3D printing is performed based on the generated slice data. The 3D printing process involves dividing the digital model into several slices according to a specified layer height, and printing layer by layer from low to high. Each layer is built upon the previous one. If the layer above the current layer is empty, the current layer cannot be supported, and printing at that location will fail. Therefore, support units need to be added to the suspended parts of the model to provide support for the model body.

[0003] In current technologies, when dealing with multiple identical models, supports can be added manually one at a time, automatically in batches for multiple models, or manually or automatically added to a single model before batch copying the model body and its supports. Of these three methods, manually adding supports one at a time is too slow, labor-intensive, and inefficient. When automatically adding supports to multiple models in batches, because the thickness and size parameters of the support units are consistent, using thicker support columns makes them difficult to cut, increasing the difficulty of removing supports after printing. Using thinner support columns, while easy to cut after printing, can lead to printing failures if the support columns at the model's center of gravity are too thin, causing breakage during LCD photopolymerization printing. Therefore, to accommodate the specific needs of the models, manual modifications are still necessary after the supports are automatically added.

[0004] Therefore, a batch of models can be automatically added to a model at once, and then the individual model supports can be manually modified and edited. Finally, the batch model preprocessing can be completed by batch copying the models and supports. However, this method is only suitable for batch copying multiple identical models and supports. When faced with multiple models with some identical features, it is still not possible to quickly add model supports. Therefore, a faster model support copying and porting method needs to be sought. Summary of the Invention

[0005] To address the problem of rapidly adding supports to multiple models with partially identical features mentioned above, this invention proposes a method that directly batch-copys model supports by selecting reference points on the same features of different models. This allows for the batch copying and porting of model supports at the same feature locations between different models. Simultaneously, when batch-adding supports to identical models is required, all supports of one model can be batch-copyed and ported to multiple identical models, achieving efficient copying and adding of model supports. Compared to batch-copying the entire model body along with its supports, this invention achieves the same effect. The technical method employed in this invention is as follows:

[0006] According to a first aspect of the present invention, two model-supported replication and porting methods are provided, wherein,

[0032] Furthermore, method 2 also includes the following steps:

If it is determined that all the triangular mesh groups C2 of the support unit are connected to the triangular mesh of model B, then proceed to step S260.

[0125] The support unit connection judgment module 345 is used to determine whether all the triangular mesh groups C2 of the support unit are connected to the triangular mesh of model B;

[0126] Support unit highlighting module 350 is used to highlight the triangular mesh group C2 of support units that are not connected to model B;

[0127] Support unit editing module 355 is used to edit the triangular mesh of the highlighted support units;

[0128] The 360 ​​End module is used to terminate the process.

[0129] Figure 4A This is Example 1 of the process for the model support replication and porting method of the present invention. As shown in the figure, when a user needs to add model supports to two models A and B, which have the same base but different features in other positions, according to the current technical background, the only way to handle this is to manually add model supports to each of the two models A and B or to automatically add model supports to each model.

[0130] Figure 4B This is Example 2 of the process for the model support replication and transplantation method of the present invention. As shown in the figure, when a user needs to add model supports to two models A and B, which have the same base but different features in other positions, according to step S115 of method 1 of the present invention, support units C1 need to be added to model A first. Specifically, they can be added manually one by one or automatically in batches.

[0131] Figure 5A Example 3 illustrates the process of supporting the replication and porting method for the model of this invention. As shown in the figure, in... Figure 4B Based on this, following steps S120-S135 of method 1 of the present invention, after selecting the "Add Support" menu command, selecting model A, and adding support unit C1 to it, by copying support unit C1 from model A to model B, support units C2 identical to C1 can be generated in batches on model B.

[0132] Figure 5B Example 4 illustrates the process of the model support replication and porting method of the present invention. As shown in the figure, when a user needs to proportionally reduce the base shown in the figure, and add model supports to two models A and B with different features in other positions in batches, the process is as follows: Figure 2B In the method described above, after copying the support units C1 of model A to model B in batches, according to steps S245-255, it is determined that not all of the triangular mesh groups C2 of the support units are connected to the triangular mesh of model B. Therefore, it is necessary to highlight the triangular mesh groups C2 of the support units that are not connected to model B, and edit the triangular meshes of the highlighted support units. The specific editing method can be deletion, or the excess support units that are not connected to the B model body can be moved to a suitable connection position as needed.

[0133] Figure 6AThis is Example 5 of the process for the model support copying and porting method of the present invention. As shown in the figure, when a user needs to add model supports to two identical models A and B in batches, according to the current technical background, model supports can be added manually or automatically to each of the two models A and B; alternatively, model B can be deleted, and model supports can be added manually or automatically to model A, and then model A and its connected multiple support units can be copied as a whole to generate model B and its support units.

[0134] Figure 6B Example 6 illustrates the process of supporting the replication and porting method for the model of this invention. As shown in the figure, in... Figure 6A Based on this, following steps S120-S135 of method 1 of the present invention, after selecting the "Add Support" menu command, selecting model A, and adding support unit C1 to it, by copying support unit C1 from model A to model B, support units C2 identical to C1 can be generated in batches on model B. In particular, when facing the same models A and B, the result of this method is the same as the method described above, which deletes model B, adds model support to model A, and then copies model A and its connected multiple support units as a whole to model B and its support units, but the implementation process is different.

[0135] Figure 7A Example 1 illustrates the process of reference porting using a reference point in the model replication and porting method of this invention. As shown in the figure, based on... Figure 6A Model A in the middle, and then by Figure 2A In step S220 of the method, when the control unit selects model A, it can automatically use the preset center point of the bottom surface of model A as reference point a, with coordinates a(a1,a2,a3); then... Figure 2A In step S225 of the method, the control unit obtains the triangular mesh group C1 data of the support unit of model A according to the copy support instruction. This example uses a support unit connection point P1(X1,Y1,Z1); then... Figure 2A In method step S230, when the control unit selects model B, it can automatically use the preset center point of the bottom surface of model B as reference point b, with coordinates b(b1,b2,b3); then... Figure 2A In step S235, the control unit performs an offset calculation on the data of the triangular mesh group C1 using the coordinate offset between reference point a and reference point b. The coordinate offset between the reference points is then Δ.

[0136] (b1-a1,b2-a2,b3-a3), correspondingly, the coordinates of the support unit connection point P2(X2,Y2,Z2) at the same position on model B are P1(X1,Y1,Z1)+△(b1-a1,b2-a2,b3-a3); therefore, from Figure 2AIn step S240, the control unit generates a triangular mesh group C2 that makes up the support unit on model B based on the offset calculation result.

[0137] Figure 7B Example 2 illustrates the process of reference porting using a reference point to support the replication and porting method of the model of this invention. As shown in the figure, based on... Figure 6B Model A in the middle, and then by Figure 2B In step S220 of the method, when the control unit selects model A, it can automatically use the preset center point of the bottom surface of model A as reference point a, with coordinates a(a1,a2,a3); then... Figure 2B In step S225 of the method, the control unit obtains the triangular mesh group C1 data of the support unit of model A according to the copy support instruction. This example uses a support unit connection point P3(X3,Y3,Z3); then... Figure 2B In method step S230, when the control unit selects model B, it can automatically use the preset center point of the bottom surface of model B as reference point b, with coordinates b(b1,b2,b3); then... Figure 2B In step S235, the control unit performs an offset calculation on the data of the triangular mesh group C1 using the coordinate offset between reference point a and reference point b. The coordinate offset between the reference points is then △(b1-a1,b2-a2,b3-a3). Correspondingly, the coordinates of the support unit connection point P4(X4,Y4,Z4) at the same position on model B are P3(X3,Y3,Z3)+△(b1-a1,b2-a2,b3-a3). Therefore, from... Figure 2B In step S240, the control unit generates a triangular mesh group C2 that forms the support unit on model B based on the offset calculation result; then... Figure 2B In step S245, the control unit determines that not all of the triangular mesh group C2 of the support unit is connected to the triangular mesh of model B; then it is necessary to highlight the triangular mesh group C2 of the support unit that is not connected to model B, and edit the triangular mesh of the highlighted support unit; the specific editing method can be deletion, or the excess support units that are not connected to the B model body can be moved to a suitable connection position as needed.
