Abstract

The invention provides a 3D printing platform spray preparation. The 3D printing platform spray preparation is prepared from the following raw materials in percentage by weight: an anionic film forming polymer, hydrophobically modified acrylate or salt thereof, a block polymer composed of at least one polyethylene glycol block and at least one polypropylene glycol block, an organic solvent, liquefied low-boiling-point organic compound gas and polysiloxane. All the components in the preparation have synergistic actions and jointly enable the sprayed spray preparation to have proper viscosity, adhesion strength, shearing dilutability and solidification speed, so that the spray preparation can be uniformly covered on the surface of the 3D printing platform; after the spray preparation is solidified, the spray preparation has proper strength; the molding precision is ensured; and the occurrence of warpage is effectively avoided.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a spray preparation for a 3D printing platform. Background technique [0002] 3D printing (also known as additive manufacturing technology) is a type of rapid prototyping technology, which is a technology that builds objects by accumulating layer-by-layer accumulation of CAD data through molding equipment and using bondable materials such as powdered metal or plastic. [0003] The mainstream 3D printing technologies mainly include four types: stereolithography (SLA), three-dimensional powder bonding (3DP), selective laser sintering (SLS), and fused deposition modeling (FDM). Among them, the 3D printer based on FDM technology uses the heating and dissolving properties of ABS, PA, nylon and other resins to form a three-dimensional model by extruding layer by layer on the printing platform. It has the advantages of fast manufacturing speed, high precision and high complexity. Manufacture...
