Polymeric material for 3D printing and preparation method of polymeric material

Abstract

The invention relates to a polymeric material for 3D printing. The raw materials of the polymeric material comprise the following components in parts by weight: 20-100 parts of polybuthylenesuccinate and 0.1-80 parts of a modifying agent, wherein the modifying agent is selected from one kind or more than two kinds of polylactic acid, a reinforcing filler and a nucleator. Polymer resins which can be used for 3D printing, disclosed by the invention, not only have high toughness, but also have high mechanical strength and high heat resistance, so that the polymeric resins have a wide application prospect in 3D printing materials.

Description

technical field [0001] The invention relates to a polymer material for 3D printing and a preparation method thereof, in particular to a polymer material mainly composed of PBS. Background technique [0002] In recent years, 3D printing has received more and more attention because of its unique advantages in forming and processing. 3D printing, also known as additive manufacturing technology, generally refers to the technology of using digital model files to directly form three-dimensional entities in a layer-by-layer manner by controlling the printing nozzle through a program. Compared with traditional molding methods, 3D printing does not require complicated molds and operating techniques. The processing process is controlled by a computer program, which is simple and safe, greatly shortens the molding processing cycle, and quickly forms parts with complex structures, which can be customized. With the deepening of research, 3D printing has gradually been widely used in med...
