Description

technical field [0001] The present invention relates to a printing composition and its preparation method and application, more particularly to a 3D printing composition and its preparation method and application, belonging to the field of rapid prototyping printing materials. Background technique [0002] With the progress and development of science and technology, at the end of 1980s, people developed Rapid Prototyping (RP) technology, also known as rapid prototyping technology, and was hailed as a major innovation and progress in the field of material manufacturing. [0003] In the field of RP technology, three-dimensional printing (Three Dimensional Printing, that is, 3D printing) is an important rapid prototyping technology. The powder material can be selectively bonded into a two-dimensional section, and then this process is repeated according to the computer design program, and the required three-dimensional solid prototype product is finally obtained through layer-by...
