Problems solved by technology

[0004] Although high-end industrial printing can realize plastic, certain metal or ceramic printing, the materials for printing are relatively expensive and scarce
In addition, the printer has not yet reached the level of maturity, unable to support the various materials that are exposed to in daily life
Researchers have made some progress in multi-material printing, but unless these advances are mature and effective, materials will remain a major obstacle to 3D printing

Abstract

The invention discloses a polymer powder material for 3D printing and relates to the technical field of 3D printing using materials. Components of the polymer powder material for the 3D printing include teflon, light calcium carbonate, camphor, octadecanoic acid, stabilizers, Pr liquid, inhibitors, silicone adhesive, terpene resin, white balls, aloe vera gel, diatom ooze, acticarbon, dicyclohexylcarbodiimide, nano modified alkyd resin, polyethylene wax, silicone, epoxy vinyl ester resin, graphene powder and organic bismuth antioxidants. The powder of the polymer powder material for the 3D printing has low agglomeration temperature, small shrinkage, small internal stress, high strength and good fluidity. Raw materials are safe and non-toxic. The density of a preparation method is increasedafter subsequent vacuum, hydrogen absorption, hydrogen crushing, dehydrogenation, air grinding and isostatic pressure. A sintering technology makes the performance of the polymer powder material morestable. The crudeness and fineness of the polymer powder material is distributed uniformly after treated, so that the surface of a printed product is more polished and delicate.

Description

Technical field: [0001] The invention relates to the related technical field of materials used in 3D printing, in particular to a polymer powder material for 3D printing. Background technique: [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing technology appeared in the mid-1990s and is actually the latest rapid prototyping device utilizing technologies such as light curing and paper lamination. The working principle of it is basically the same as that of ordinary printing. The printer is filled with "printing materials" such as liquid or powder. After being connected to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real object. [0003] The working principle of the so-called 3D...
