Abstract

The invention discloses a large 3D printing support material and a preparation method thereof. The large 3D printing support material comprises the following main materials: calcium carbonate fillingmaster batch, a thermoplastic elastomer, a foaming agent, a surface modifier, a plasticizer and an antioxidant, wherein the calcium carbonate filling master batch is taken as a main ingredient, and the thermoplastic elastomer is a binding agent. The main materials such as the calcium carbonate filling master batch and the thermoplastic elastomer are cheap in materials and environmentally friendly;through the addition of the foaming agent, the strength and tenacity of the material are reduced, the material is convenient to disassemble, and through the surface modifier, the adhesiveness of a supporting surface with the main body material is increased; in the application of 3D printing, the support material is high in plasticity, the support material can be completely separated from the mainbody material, the support material can be directly dismantled without the use of a tool due to low strength and tenacity, and the shape of a molding part cannot be damaged due to the stripping of the support material; and compared with a water-soluble support material, the support material is more environmentally friendly and economical since water is not needed, and the support material is moreapplicable for 3D printers using screw extrusion.

Description

technical field

[0001] The invention relates to 3D printing materials, in particular to a large-scale 3D printing support material and a preparation method thereof. Background technique

[0002] 3D printing mainly includes FDM fused deposition, SLS laser sintering and other technologies. Among them, FDM fused deposition is the most widely used. This technology is to melt polymer plastics and accumulate them layer by layer according to a specific trajectory to print out model products. When there is a suspended or hollow structure in the product, select the support material for printing and molding, and remove it after printing. Support materials play an important role in the printing of special-shaped parts, which is related to the application and promotion of printing. With the development of 3D printing in the direction of large-scale and industrialization, the use of screw extrusion can obtain faster printing speed and plasticizing effect of materials. Considering the p...
