Problems solved by technology

At present, the commonly used polystyrene linear materials for 3D printing mainly include non-transparent materials such as ABS and HIPS, while transparent polystyrene materials are limited due to their high rigidity, poor impact resistance, fragility and bending resistance. It is used as a linear material for 3D printing, so transparent polystyrene linear materials for 3D printing have not been reported yet.

Abstract

The invention relates to a transparent polystyrene linear material for 3D printing and a preparation method thereof, which is prepared from the following raw materials: transparent polystyrene and transparent styrene-butadiene block copolymer with a mass ratio of 0-90: A compound of 100-10; a transparent pigment accounting for 0-5% by weight of the compound; and an antioxidant accounting for 0-5% by weight of the compound. The preparation process of the polystyrene wire rod for 3D printing of the present invention is simple, low in cost, good in fluidity, high in strength, high in flexibility and can be bent at will, and has high transparency. Vinyl wire such as ABS, HIPS and other linear materials have low fluidity and are easy to clog printer nozzles and are opaque.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a polystyrene linear material for 3D printing and a preparation method thereof. Background technique [0002] 3D printing technology originated in the United States at the end of the 19th century, even before the Internet. 3D printing began to develop as early as the 1980s, but it was not until recent years due to the continuous advancement of information technology, the continuous updating of mechanical automation and the promotion of the Internet that the "software core" of 3D printing - "digital model" and "hardware" "Basic" has been developed at a high speed, the cost of 3D printers has continued to drop, and the golden age of 3D printing technology applications has officially arrived. 3D printing technology is called the "third industrial revolution" and belongs to the field of additive intelligent manufacturing. The manufacturing process is to first design and process t...
