Description
Technical Field
The present utility model relates to support structures, and in particular to support structures for 3D printing of metallic materials.
Background
The existing 3D printing technology can realize the processing of parts with complex structures, realize the free modeling of products, provide wider space for structural design, and become an important processing technology for supporting the personalized customization of products.
The 3D printing technology needs to add a supporting structure to the suspended part of the model in the printing process of the part model so as to ensure that products can be successfully stacked layer by layer in the 3D printing process.
However, for 3D printing of metal parts with complex structures, the difficulty in removing the supporting structure after printing is finished, the processing procedure is complex, and the labor intensity is high, so that the application of the 3D printing technology in engineering is restricted.
The existing 3D printing support method for the metal material mainly comprises two types:
(1) Taking a Selective Laser Melting (SLM) 3D printing method as an example, the supporting structure and the part matrix are melted layer by layer simultaneously by powder materials, and the obtained supporting structure is a solid body of the same material as the part matrix; the interface between the supporting structure and the part matrix is connected in a completely molten mode, so that stable supporting and part deformation preventing effects can be provided, but the problem is that the supporting and removing difficulty is high, the supporting is usually removed in a clamping or linear cutting mode, the machining process is complex, the labor intensity is high, the production efficiency is low, meanwhile, the quality of the surface of the part after the supporting is removed is poor, certain post-treatment measures are adopted for improvement, and the machining cost is increased.
(2) Taking a Selective Laser Sintering (SLS) 3D printing method as an example, the cantilever structure in the printing process is directly supported by unsintered raw material powder, so that the printing method does not need a complex supporting removing process, and only needs a hairbrush to remove powder on the surface of a part; however, the material used in the SLS printing technology needs to be added with a certain proportion of binder powder besides the main metal powder, the binder powder is generally organic resin with a lower melting point, the metal powder is not melted in the printing process, and the metal powder is bonded into a part shape by using the melting of the binder, so that the strength of the part obtained by the printing method is very low, and the part can only be used as a decoration, and cannot meet the use requirement of a bearing structure; in sum, on the basis of meeting the performance use requirements of 3D printing parts, a quick, economical and easily-removed supporting structure is designed to meet the requirements of high efficiency and low cost in industrial production, and is a problem expected to be solved by enterprises.
