Abstract

The invention discloses a low warpage ABS material for 3D printing, and a preparation method thereof, wherein the low warpage ABS material comprises, by weight, 10-50 parts of a PB-G-SAN copolymer, 50-90 parts of a SAN resin, 5-30 parts of an anti-warpage filler, 0.2-5 parts of a coupling agent, 0.1-1 part of an antioxidant, 1-5 parts of a lubricant, 0-0.5 part of an anti-ultraviolet agent, and 0-1 part of toner. The preparation method comprises: weighing various raw materials according to the ratio, carrying out uniform mechanical mixing, extruding the mixed material through a twin-screw extruder, carrying out normal temperature cooling, carrying out air drying, granulating to prepare a modified ABS particle, and extruding the modified ABS particle by using a 3D printing material extruder to produce the low warpage ABS material for 3D printing. According to the present invention, with the application of the prepared ABS material for 3D printing in printing, the advantages of uniform and smooth printing, no drawing, strong adhesion between the layers, low warpage and high size precision of the product, and printing of the large-size product can be provided.

Description

technical field [0001] The invention relates to a 3D printing material, in particular to a low warpage ABS material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing (additive manufacturing) technology is one of the most representative technologies of the third industrial revolution, which will promote the industrial transformation of the whole society. Currently, Fused Deposition Modeling (FDM) 3D printing technology is the most popular 3D printing technology, but the development of 3D printing materials limits the development of related industries. The raw materials used in FDM are usually thermoplastic polymer materials, including acrylonitrile-butadiene-styrene copolymer (ABS), polylactic acid (PLA), polyamide (PA), polycaprolactone (PCL), etc. It is widely used in model making, mold making, biomedical material preparation and school education. [0003] ABS is a widely used high molecular polymer, where A stands for acrylonitri...
