Problems solved by technology

[0003] Fused deposition rapid prototyping (FDM) is a process in 3D printing technology. The consumables used are generally thermoplastic polymer materials. Electric heating is used to heat the filament to a temperature higher than its melting temperature. Plane movement, coating the molten material on the worktable, and stacking it layer by layer to form a three-dimensional workpiece. PS itself has the advantages of good thermal melting, easy extrusion, stable printing process, high product strength and excellen...

Description

technical field [0001] The invention relates to a preparation method of high-toughness and high-flow PS used in 3D printing materials, which belongs to PS / toughener composite material and a preparation method thereof. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, refers to the molding technology that uses physical and chemical methods to add materials layer by layer and accumulate molding. The difference from traditional molding manufacturing methods is that 3D printing technology uses rapid automatic molding systems and computer data. Models can be combined to produce prototypes with complex shapes without additional machining and mold manufacturing. In recent years, 3D printing technology has received more and more attention and has achieved rapid development. It is widely used in aerospace, jewelry, film and television, home appliances, archaeology, education and other fields. [0003] Fused deposition rapid protot...
