A 3D printing cross-section matching method, composite forming method and cross-section repairing method

Abstract

The invention discloses a 3D printing cross-section matching method, which adjusts the position of the vibrating mirror coordinate system or the subdivision coordinate system through coordinate transformation, so that the positions of the section relative to the vibrating mirror coordinate system and the subdivision coordinate system are consistent. The method is applicable to a 3D printing composite forming method disclosed in the present invention. First, the basic part of the part is formed by machining, and then the complex structure part is formed by 3D printing technology; before forming the complex structure part, the The section matching method completes the composite section matching of the basic part and the complex structure part. This cross-section matching method is also applicable to matching the cross-section of the printed part of the current layer of the part with the cross-section of the current layer of the part in the subsection software when the 3D printing process fails and reprints. The method is simple and easy to implement, and can effectively ensure that the subsequent printing can be accurately combined with the formed part, ensuring the forming quality of the 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...
