Abstract

The invention provides a high-performance 3D (Three Dimensional) printing supply alloy material. The high-performance 3D printing supply alloy material comprises, in parts by weight, 20.0-50.0 parts of polylactic acid, 50.0-80.0 parts of high impact polystyrene, 0.1-5.0 parts of compatilizer and 0.2-3.0 parts of auxiliaries, wherein the compatilizer comprises one or more than two, matched with each other in use, of a maleic anhydride grafted high polymer, a terpolymer copolymerized with styrene, acrylonitrile and glycidyl methacrylate (SAG), and a terpolymer copolymerized with methyl methacrylate, butadiene and a styrol copolymer (MBS). The high-performance 3D printing supply alloy plastics prepared from the high-performance 3D printing supply alloy material are non-toxic, low-carbon and environment-friendly, low in alloy material cost, excellent in combination properties, and very high in economic value and wide in market prospect.

Description

Technical field [0001] The invention relates to the field of 3D printers, in particular to a high-performance 3D printing consumable alloy material. Background technique [0002] The existing 3D printing consumables mainly include polylactic acid, ABS, nylon618, PVA, etc. Due to the limitations of the above-mentioned materials, the cost of polylactic acid materials is high, and the materials are easily deformed above 55°C; ABS (acrylic acid / butadiene) / Styrene terpolymer), a common engineering plastic with heavy processing odor and easy to deform during extrusion processing; nylon 618, a nylon material, expensive, difficult to process, strong in processing odor, and harsh processing environment; PVA Water-soluble materials are mainly used for printing supporting materials with a small amount, and the processing is prone to produce toxic gases due to the decomposition of PVA. Plastic alloy is a new type of material blended with two or more resins. In addition to the advantages o...
