Problems solved by technology

[0048] 4), reducing the printing speed and printing quality
Since the contour curve of the workpiece is often composed of a large number of straight lines (including oblique lines), this further affects the printing speed and printing quality of the CNC system.
[0052] 5) The readability of the G code program is poor, and it is not easy to use and exchange and share. Whether it is manual programming or automatic programming, its programming and post-processing are very specialized work, requiring professional programmers
[0054] Therefore, as a programming interface, there is a contradiction between the existing G code program and its programming method and the requirements of DIY, which has become one of the bottlenecks for the further development of personal manufacturing. G code and the existing programming technology based on G code cannot be adapted to 3D The democratization of printing technology

Embodiment Construction

[0226] As we all know, 3D printing can be divided into two types of forming technologies, selective deposition and selective connection. Selective deposition The molten printing material is selectively deposited, and the solid ratio is formed. Selective connection lays down the printing material first, and then selectively sprays the adhesive for bonding and molding; or laser selective scanning for solid ratio molding.

[0227] Generally speaking, no matter what kind of molding technology is used, the basic principle of a 3D printer is a liftable workbench for laying printing materials. One or more nozzles for ejecting (plastic / metal / adhesive) droplets, (plastic / ceramic / metal) powders; or for emitting laser beams. The nozzle moves in a curve relative to the worktable under the control of the X-axis / Y-axis, and the Z-axis controls the lifting of the worktable.

[0228] Any complex three-dimensional solid can be decomposed into a series of thickness δz i The superposition of ...

Abstract

The application discloses a CNC system for 3D printing, a generation method of printed documents and a 3D entity printing method. Computer digital control, 3D entity generation and printing materials are three major basic techniques for 3D printing. According to the application, printing curves are planned with high precision; printed documents replace the general code printing program, and the G code programming is cancelled; the printing program writing likes short message writing; 'numerical control implementation just likes mobile phone playing, and programming just likes message sending'; the popular targets that 'everybody can use a 3D printer, and can program' is realized. The technique admittance threshold and cost of the CNC system in 3D printing are reduced obviously so as to enable to the 3D printing technique to be popular.

Description

technical field [0001] This application belongs to the field of 3D printing, and specifically relates to a computer numerical control system (Computer Numerical Control system, CNC system) and a programming interface for 3D printing, as well as a method for generating a printing file and a method for printing a three-dimensional entity. technical background [0002] In academia, especially in the manufacturing industry, a variety of rapid prototyping technologies (Rapid Prototype) are summarized by additive manufacturing, corresponding to traditional subtractive manufacturing. [0003] In 2009, the Additive Manufacturing Standards Committee (ASTM F-42) of the American Society for Testing and Materials defined additive manufacturing as: based on 3-D model data, using a layer-by-layer stacking method opposite to subtractive manufacturing, by connecting materials to the process of producing entities. (F2792-10 standard: The process of joining materials to make objects from 3-D...
