Example Embodiment

[0023] Example

[0024] The 3D printing method of composite material parts based on a three-cylinder molding machine of the present invention includes the following steps:

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

[0026] On the basis of the three-dimensional model, identify parts of different materials. Parts of the same material (or a part of a part) use the same logo, and parts of different materials use different logos;

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

[0028] Pre-store the required two powder materials in the powder cylinder of the 3D printer, and control the 3D printer's system to slice the contour information of the 3D model, and control the two powder feeding cylinders to supply powder to the molding cylinder, laser (or electron beam) melting and sintering Powder, this completes a layer of processing;

[0029] Control the forming ...

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...
