Abstract

The invention discloses a G code generation method for pulse laser 3D printing, and the method comprises the steps: carrying out the slicing of a to-be-printed 3D model, and obtaining a plurality of to-be-printed sections; acquiring a processing path and process parameters of each layer of section in a continuous laser 3D printing mode; according to the machining path and the technological parameters of the section of each layer in the continuous laser 3D printing mode, determining the machining path and the technological parameters of the section of the layer in the pulse laser 3D printing mode; and generating a 3D printing G code of the cross section of the layer according to the processing path and the process parameters of the cross section of each layer in the pulse laser 3D printingmode. According to the invention, the method can effectively solve a problem that a conventional 3D printing G code generation method is not suitable for pulse laser 3D printing because of the designfor continuous laser 3D printing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and more specifically relates to a method for generating G codes for pulsed laser 3D printing. Background technique [0002] In the process from product digital CAD model design to 3D printing, the participation of basic elements such as the construction of 3D model, 3D printer and 3D printing layered slicing software is indispensable. Among them, the 3D printing layered slicing software is the driver between the 3D model and the 3D printer, and its main functions include layered slicing of the 3D model, path planning of the contour surface, and calculation of process parameters. As a standard file format of 3D printing technology, STL model is used in most 3D printing systems. At present, layered slicing software for STL models is emerging in an endless stream, such as Cura, HORI 3D printing slicing and control system, Sinplify3D and Makerbot print, etc. However, the G code generation meth...
