Abstract

The invention provides a 3D (Three Dimensional) printing material formula taking a wood chemical component as a main raw material, belongs to the technical field of 3D printing and in particular relates to the technical field of a 3D printing formula taking the wood chemical component as the raw material. The 3D printing material formula taking the wood chemical component as the main raw material,provided by the invention, is prepared from the following components in parts by weight: 10 to 30 parts of high polymer plastic, 2 to 10 parts of cellulose, 40 to 60 parts of hemicellulose, 30 to 50parts of lignin, 2 to 5 parts of a lubricant and 5 to 8 parts of a coupling agent. The formula provided by the invention can take the wood chemical component as the main raw material for carrying out3D printing.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, in particular to the technical field of 3D printing formulas using wood chemical components as raw materials. Background technique [0002] 3D printing, also known as rapid prototyping technology, is also called additive manufacturing technology. It does not require traditional tools, fixtures and machine tools, but is based on digital model files, using adhesive materials such as metal powder or plastic Layer-by-layer printing technology to manufacture objects of any shape. 3D printing technology is the integration of multidisciplinary technologies such as mechanical engineering, computer technology, numerical control technology, and material science. The most difficult and core technology of 3D printing is the development of printing materials. Therefore, the development of more diverse and multifunctional 3D printing materials has become a hotspot and key to future research and applicati...
