Distributed storage and reading method and device for 3D printing model slices

Abstract

The invention provides a distributed storage and reading method and device for 3D printing model slices, and the method comprises the following steps: processing the 3D printing model slices into a plurality of blocks, generating slice layer information files with the same number as the 3D printing model slices and a plurality of actual data files with the same number as the plurality of blocks, a scanning path folder corresponding to the 3D printing model is generated at the same time, and the scanning path folder is located in the printing platform folder; the actual data files are stored in the blocks in a one-to-one correspondence mode, and the blocks and the slice layer information files are stored in a scanning path folder; establishing an index information file in the scanning path folder; and the index information file is analyzed, and a current layer data file to be subjected to 3D printing is read. According to the distributed storage and reading method for the 3D printing model slices, the actual data file is stored in the blocks, the index information file is analyzed, the data information of the current layer needing to be printed is accurately and rapidly read, and the reading speed is increased.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method and device for distributed storage and reading of 3D printing model slices. Background technique [0002] Powder bed laser 3D printing technology has the advantage of ultra-high resolution, so that complex objects such as bionic porous structures can be printed. In the printing process, in order to accurately represent the geometric features of complex objects, the printing data file contains a large amount of coordinate data and parameter data, which are all stored in the same folder, so that the printing data file can easily reach the GB level. For example, a traditional printer can print a large perforated square with a print file of about 7GB. In addition, multiple objects can be placed on the printer's printing platform at the same time, further increasing the size of the data file in a multiplicative relationship. [0003] The oversized data file brings the f...
