Abstract

The invention discloses an STL-based 3D printed file data processing method and relates to the technical field of 3D printing. The STL-based 3D printed file data processing method comprises the following steps of S1, conducting modeling on an article to be subjected to 3D printing through 3D modeling software; S2, determining the file format of a model obtained in the step S1 to be STL; S3, conducting error correction on an STL file; S4, conducting scattering and slicing on the file obtained in the step S3 to obtain an outline; S5, conducting filling on the model according to the outline obtained in the step S4; and S6, outputting the file after completion of filling. Through the STL-based 3D printed file data processing method provided by the invention, data processing can be simplified,occupied space can be reduced, redundant data can be eliminated, and accordingly, the overall working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a data processing method of an STL-based 3D printing file. Background technique [0002] At present, there are many kinds of model file formats used in 3D printing technology, such as CLI, STL, PC and SLC, etc. Among them, the STL model file format has been used as the standard data conversion of 3D printing rapid prototyping technology, which was proposed by 3D System of. The slicing algorithm is to discretely layer the 3D STL model to obtain layer-by-layer contour lines, and then fill the contour lines by raster scanning or contour offset to generate various types of printing paths. [0003] General typical slicing algorithms based on STL files include: (1) Direct intersection slicing algorithm: According to common slicing thinking, first determine the slice height Z, and calculate and compare the positional relationship between the three vertices of all triang...
