FIG. 2 is a flowchart of a method for 3D printing a lattice provided by an embodiment of the present invention. As shown in FIG. 2 , the method of this embodiment may include:

S201. Obtain lattice information of multiple lattices to be printed, where the lattice information includes spatial coordinate information and topology information of each lattice node in each lattice;

In this embodiment, the spatial coordinate information of each lattice node is based on a spatial coordinate system, and the spatial coordinate system may be a rectangular space coordinate system or a spherical coordinate system, which is not limited in this embodiment. .

For convenience of description, the following description will be given by taking the space coordinate system as a rectangular space coordinate system as an example. The node space coordinate information of each lattice is the real coordinates of the three spatial directions of X, Y, and Z in the rectangular space coordinate system, and the topology information indicates the connection relationship between different nodes of the lattice.

The spatial coordinate information and topology information of each lattice node are represented by floating point values, for example, the spatial coordinate information of a certain lattice node may be (0.2456, 0.448, 0.448).

S202, encoding the node space coordinate information of each lattice to generate a coordinate encoding of the lattice; wherein, each encoding value in the coordinate encoding is an integer;

In the prior art, since the node space coordinate information used in the test is a floating-point value, the operation efficiency of the operation required for the test is affected to a certain extent during the test, which also reduces the test efficiency and affects the subsequent analysis of the lattice printing efficiency.

Different from the prior art, in order to facilitate the rapid testing of the lattice, in this embodiment, the spatial coordinate information of the nodes of each lattice is also encoded, and the floating points in the three spatial directions of X, Y, and Z are coded. Point value coordinates are converted to integer coordinates. Among them, the purpose of coordinate conversion is to convert floating point coordinates into integer coordinates, and the implementation method can adopt the existing technology, including but not limited to: conversion model, conversion mapping table, scaling factor, etc. limited.

Still taking the above lattice as an example, if the lattice includes 3 nodes, and its spatial coordinate information is (0.2456, 0.448, 0.448), (0.2445, 0.224, 0.224), (0.489, 0.448, 0.448), then the lattice The coordinate encoding of the grid can be e.g.

0245604480448-0244802240224-0489-0448-0448.

S203, using the coordinate encoding of each crystal lattice to perform a lattice test on each crystal lattice;

In this embodiment, the lattice test for the lattice may include, but is not limited to, the validity test and the repeatability test of the lattice.

The validity test refers to checking whether the lattice nodes are distributed symmetrically in various spatial directions. Specifically, the lattice validity test for the lattice nodes is implemented based on the coordinate encoding of each lattice.

For example, if the coordinate code of a certain lattice is 02-22-11-00-20, then when testing the validity of the coordinate code, map the coordinate code to the Cartesian coordinate system to obtain the coordinates of the center of the lattice The code is 11, the node coordinate codes 02 and 20 are symmetric about the center coordinate code, and the node coordinate codes 22 and 00 are also symmetric about the center coordinate code. It can be seen that the lattice is center-symmetric, indicating that the lattice corresponding to the coordinate code is valid. of;

For another example, the coordinate code of another lattice is 02-22-11-20, then when the validity test of the coordinate code is performed, the coordinate code is mapped to the rectangular coordinate system, and the center coordinate code of the lattice is obtained as 11 , the node coordinate codes 02 and 20 are symmetric about the center coordinate code, and the node coordinate code 22 has no node coordinate code that is symmetric about the center coordinate code. It can be seen that the lattice is not center-symmetric, indicating that the lattice corresponding to the coordinate code is invalid. .

The repeatability test refers to checking whether the nodes of different lattices are repeated. Specifically, the lattice repeatability test for each lattice is realized according to the consistency between the coordinate codes of each lattice.

For example, the coordinates of a lattice are coded as 02-22-11-00-20, and the coordinates of another lattice are coded as 22-42-33-20-40, then when repeating the lattice test , since some of the coordinate codes of the two lattices are repeated, it means that the nodes of these two lattices are repeated;

For another example, the coordinate code of a lattice is 02-22-11-00-20, and the coordinate code of another lattice is 32-21-31-41-30, then when repeating the lattice test, Since the coordinate codes of the two lattices are not repeated, it means that the two lattices are not repeated;

Of course, in the above test, the lattice validity test can be performed on each lattice first, and when the validity test fails, the lattice needs to be redesigned, and the validity test is continued on the redesigned lattice. After all the lattices have passed the validity test, the lattice needs to be tested for repeatability, and only the lattices that pass the repeatability test can be printed.

S204 , performing three-dimensional printing on each lattice according to the spatial coordinate information and topology information of the lattice nodes of each lattice that has passed the test.

In this embodiment, all the lattices that have passed the lattice validity test and the repeatability test are printed. Taking the rectangular coordinate system as an example, FIG. 8 is a schematic diagram of lattice printing in the embodiment of the present invention.

Specifically, the real coordinates and topology information of each lattice in the three spatial directions of X, Y, and Z are used for printing.

By adopting the above-mentioned method in the embodiment of the present application, the integer coding value in the coordinate coding can be tested during the lattice test, the test efficiency is significantly improved compared with the prior art, and the overall printing efficiency is also improved. promote.

S304, using the coordinate encoding of each crystal lattice to perform a lattice test on each crystal lattice;

S305 , performing three-dimensional printing on each lattice according to the spatial coordinate information and topology information of the lattice nodes of each lattice that has passed the test.

Different from the previous embodiment, in this embodiment, the processing of the lattice node coordinates will use the scaling factor in the spatial direction, so that the processing efficiency of the coordinate encoding can be effectively improved, thereby improving the testing efficiency.

Specifically, after obtaining the node spatial coordinate information and topology information of the multiple lattices to be printed, for each spatial direction in the three-dimensional space, the scaling factor in the spatial direction is determined according to the spatial coordinate information; then, using The scaling factor in each spatial direction is used to perform coordinate scaling processing on each spatial coordinate information to obtain the coordinate encoding of the lattice.

Further, still taking the Cartesian coordinate system as an example, Figure 5 is a schematic diagram of the process of converting the floating point value coordinates of the lattice node to integer coordinates. As shown in Figure 5, the coordinates of node 1 are (0.0, 2.5), and the coordinates of node 2 are (1.5, 2.5), the coordinates of node 3 are (0.0, 0.0), the coordinates of node 4 are (1.5, 0.0), and the scaling factor in the X direction is set to 1.5 and the scaling factor in the Y direction is 2.5. By using the X and The scaling factor in the Y direction can transform the lattice node coordinates, so that the transformed node coordinates are: node 1(0,1), node 2(1,1), node 3(0,0) and node 4 (1,0), the transformed coordinates will form the coordinate code 01-11-00-10.

Of course, in one of the optional implementation manners, the same scaling factor may be used for the scaling factors of each spatial direction. In another optional implementation manner, the scaling factors in each direction are independent of each other, and coordinate scaling processing can be performed in three spatial directions respectively.

Compared with the foregoing embodiments, the present embodiment can implement the integer encoding of the lattice node coordinates more efficiently by means of the scaling factor in the spatial direction, thereby improving the testing efficiency of the lattice.

In an optional embodiment, in order to make the lattice testing more efficient, on the basis of the above-mentioned embodiments, FIG. 4 is a flowchart of another method for 3D printing a lattice provided by an embodiment of the present invention, as shown in FIG. 4 . shown, the method includes:

S404. Perform a lattice test on each lattice according to the node matrix of each lattice;

Further, after S405, it can also include:

S406. When printing the lattice, various operations are performed on the node matrix to realize the transformation of the size, direction and shape of the lattice.

In this embodiment, for the specific implementation process and technical principle of step S401 , step S402 and step S405 , please refer to the relevant descriptions in step S201 , step S202 and step S204 in the method shown in FIG. 2 , which will not be repeated here.
