Abstract

The invention discloses 3D printing supplies with stainless steel luster. The 3D printing supplies is characterized by comprising the following ingredients (by weight): 60-70% of PLA plastic, 20-40% of stainless steel powder and auxiliary agents, wherein density of the PLA plastic is 1.2-1.3 kg / L, and intrinsic viscosity IV is 0.2-8 dL / g; the stainless steel powder is spherical powder with average particle size being 400-500 meshes and degree of sphericity being greater than 0.7; and the auxiliary agents contain, by weight, 0.4-0.6% of a coupling agent, 2-3% of a lubricant and 0.2-0.4% of a compatilizer. The stainless steel powder is more preferably 316L stainless steel. According to the 3D printing supplies, the spherical stainless steel powder is added into PLA plastic, and the auxiliary agents are added in cooperation, which are beneficial to extrusion and shaping of a screw machine. The printed article has matte luster of stainless steel. Through working and grinding, bright stainless steel luster can be obtained.

Description

technical field [0001] The invention relates to a 3D printing consumable, more precisely, a 3D printing consumable with stainless steel luster. Background technique [0002] With the advancement of science and technology, 3D printing technology has begun to be widely popularized. Through computer control, "printing materials" can be superimposed layer by layer, and finally the blueprint on the computer can be turned into a real object. Existing printing materials generally include two types: ABS (acrylonitrile-butadiene-styrene copolymer) and PLA (usually polylactic acid), especially the latter, which has attracted much attention due to its ability to degrade in the natural environment . Existing PLA consumables have a plastic luster on the surface of the product, and there is no consumable that presents a stainless steel luster on the market. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providin...
