Abstract

The invention relates to a sectioning method of a three-dimensional model and a three-dimensional printing device. The three-dimensional printing device comprises a central processor and a graph processor. The method comprises the following steps: the central processor converts the three-dimensional model into an STL file and stores the STL file; the central processor groups triangular patches bymeans of a plurality of cutting planes, so that the triangular patches intersected with the same cutting plane are in a same group; the graph processor processes the grouped triangular patches in parallel to obtain slice section data, wherein the slice section data is intersection data of the cutting planes and the triangular patches; the central processor generates slice section images accordingto the slice section data and stores the slice section images. By grouping the triangular patches by the cutting planes by means of the central processor and processing the grouped triangular patchesin parallel by means of the graph processor, the sectioning calculating efficiency of the three-dimensional efficiency can be improved effectively, so that the 3D printing efficiency is further improved, and efficient manufacturing demands are met.

Description

technical field [0001] The invention relates to the field of three-dimensional model printing, in particular to a three-dimensional model slicing method and a three-dimensional printing device. Background technique [0002] With the continuous improvement of social computing capabilities, "social manufacturing" that allows users to participate has become inevitable. The concept of "social manufacturing" is to allow users to participate in the process of product ideation, design and manufacturing, and this manufacturing method is mainly 3D ( 3Dimensions, three-dimensional) printing. Unlike traditional manufacturing processes such as turning, milling, cutting, stamping, tooling, etc., additive manufacturing starts with a 3D model and produces items by stacking materials layer by layer. [0003] The essence of 3D printing lies in layered manufacturing, and slice calculation is the process of obtaining layered information of three-dimensional objects, so this process is particu...
