3D printing section matching method, composite forming method and section restoration method

Abstract

The invention discloses a 3D printing section matching method which enables a section to be consistent relative to the positions of a galvanometer coordinate system and a subdivision coordinate system through coordinate transformation and position adjustment of the galvanometer coordinate system or the subdivision coordinate system. The 3D printing composite forming method includes the following steps of completing basic part forming of a part through machining, adopting a 3D printing technology to form the forming composite structure part of composite structure, and completing composite section matching of a basic part and a complex structure part through the section matching method before the composite structure part is formed. The section matching method is also suitable for matching the section of a printed part on the current layer with the part section on the current layer in the subdivision software when reprinting is needed due to fault during 3D printing. The 3D printing section matching method is simple, easy to realize and capable of effectively ensuring the accurate combining of subsequent printing and formed part and ensuring the forming quality of part.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing section matching method, and also relates to a composite forming method and a section repairing method applicable to the method. Background technique [0002] 3D printing technology is based on three-dimensional CAD model data, by adding materials to manufacture parts layer by layer. It is based on the computer three-dimensional design model, through the software layered discrete and numerical control forming system, the material is piled up layer by layer with high-energy beams, and finally superimposed and formed to produce a physical product. 3D printing technology is more efficient, more convenient, and has broader development prospects. It can use single metal or mixed metal powder to directly manufacture metal parts with metallurgical bonding, close to 100% compactness, high dimensional accuracy and good surface roughness. . It comprehensivel...
