Abstract

The invention discloses a 3D printing method of composite parts based on a three-cylinder former. The method includes the steps of designing a part model with 3D software; based on the 3D model, marking parts of different materials, applying same marks to parts of same material, and applying different marks to parts of different materials; slicing and layering the 3D model; pre-storing required powder material in each powder cylinder of a 3D printer, controlling a system of the 3D printer according to outlines of slices of the 3D model, controlling two feed cylinders to feed the powder to a forming cylinder, and laser-melting and sintering the powder to finish one layer; controlling to descend the forming cylinder by one layer thickness, repeating the step of powder spreading, stacking layer by layer, and completing 3D printing of composite once directly. The method has the advantages that part structures are lightened and structure attributes and function attributes are combined by making full use of excellent performances of metal materials and nonmetal materials.

Description

technical field

[0001] The present invention relates to the molding and manufacturing technology of composite material parts, in particular to a 3D printing method for composite material parts based on a three-cylinder molding machine. Background technique

[0002] Compared with traditional machining such as turning, milling and planing, metal 3D printing, as an additive manufacturing method (Addictive Manufacturing), can manufacture various complex structures and give full play to the efficiency of materials. It is one of the main methods of green manufacturing in the future. Its advantage lies in expanding the space for product creativity and innovation. Designers are no longer constrained by traditional craftsmanship and manufacturing resources, and reduce product R&D innovation costs, shorten R&D cycles, and enhance process manufacturing capabilities. Therefore, in aerospace, biomedical, industrial molds, automobiles, etc. Manufacturing and other industrial fields have u...

Embodiment

[0024] The present invention is based on the 3D printing method of the composite material part of three-cylinder molding machine, comprises the following steps:

[0025] Use 3D software (SolidWorks, ProE, UG, etc.) to design the part model, or use reverse engineering (CT scanning, 3D scanner, etc.) to reverse the 3D model of the part;

[0026] On the basis of the 3D model, parts of different materials are marked, parts of the same material (or a part of the part) use the same mark, and parts of different materials use different marks;

[0027] Then the 3D model is sliced ​​and layered;

[0028] Prestore the two required powder materials in the powder cylinder of the 3D printer, control the 3D printer system according to the contour information of the 3D model slice, and control two powder feeding cylinders to supply powder to the molding cylinder, and laser (or electron beam) melting and sintering powder, so that one layer of processing is completed;

[0029] Control the for...
