An integrated 3D laser printing multi-component preparation method

Abstract

The invention relates to an integrated 3D laser printing multi-component preparation method, which includes the following steps: 1) material preparation stage: according to the design requirements of the multi-component metal powder type, different metal powders are fully and uniformly mixed according to the proportion using a powder mixer; 2) 3D printing stage: In the forming room of the additive manufacturing machine tool, all parts are digitally placed; the computer control system controls the position of the powder feeding and cladding nozzle of the 3D printer, and the powder feeding rate and powder feeding volume of the powder cylinder, Start the laser and the inert gas protection gas supply device, and perform laser cladding deposition forming layer by layer to form an integrated multi-component formed part; 3) post-processing stage of the formed part. It has the advantages of reasonable method step design, effectively solving the problem of integrated design and manufacture of multi-component parts, improving production efficiency, reducing product processing and manufacturing costs, saving time, and reducing environmental pollution.

Description

technical field

[0001] The invention relates to the technical field of additive manufacturing of multi-component mechanical parts, in particular to an integrated 3D laser printing multi-component preparation method. Background technique

[0002] Traditional parts manufacturing and processing methods require the production and assembly of raw materials through cumbersome processes such as cutting, forging, bending, etc., which consume a lot of manpower and material resources, have low operation efficiency, and cannot guarantee better accuracy. Usually, the technological loss and non-manufacturing loss produced by CNC machine tools in the production process of mechanical parts are very serious, and the man-hours consumed are directly related to the processing complexity of the parts. At the same time, machining with CNC machine tools is all subtractive manufacturing, so it is impossible to realize the integrated manufacturing of different components. 3D printing technology at...
