Multi-axis milling and laser fusion composite 3D printing equipment

Abstract

The invention relates to the technical field of 3D printing equipment, and discloses multi-axis milling processing and laser fusion composite 3D printing equipment, including a base, on which a processing platform is arranged; Powder structure, the upper part of the processing platform is equipped with a laser emitting structure that melts the metal powder layer to form a single-layer or multi-layer approximate shape, and a milling head that can move in a three-dimensional space. The milling head has a rotatable and oscillating milling tool. 3D printing equipment integrates the traditional removal-type precision machining mainly based on milling and the incremental stacked manufacturing process mainly based on laser beam fusion 3D printing, and overcomes the defects of traditional 3D printing technology in terms of size and shape accuracy. It also overcomes the constraints of cutting processing on the complexity of parts and other aspects, and does not need to perform secondary processing on the processed parts, avoiding the problems of current clamping difficulties, large processing errors, deformation of parts during processing, and difficult processing.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to multi-axis milling processing and laser fusion composite 3D printing equipment. Background technique [0002] Metal melting 3D printing technology (Selective Laser Melting, SLM) uses high-brightness laser to directly melt metal powder materials without binders, and directly forms arbitrary complex structural parts with the same performance as castings from 3D models. [0003] Although metal fusion 3D printing technology can form parts that reach the casting strength level, the shape error of the formed parts is large and the surface finish is not high. In this way, the formed parts need to be processed twice by traditional machining methods. Only by processing can the shape and surface accuracy required by the aviation manufacturing industry be obtained. However, most parts in the aerospace industry, such as engine nozzles, blades, honeycomb structure combustion ch...
