Description

technical field

[0001] The invention belongs to the technical field of 3D printing materials, and in particular relates to a medical three-dimensional printing alloy material and a preparation method thereof. Background technique

[0002] 3D printing technology, also known as additive manufacturing according to its manufacturing process, belongs to a kind of rapid prototyping technology. It uses powdered metal or plastic and other bondable materials, and finally prints directly Produce products and form "digital manufacturing". 3D printing technology originated from the photographic sculpture and landform forming technology researched in the United States at the end of the 19th century, but limited by the technical conditions at that time, no breakthroughs were made. In the 1980s, with the vigorous development of computer technology and new material technology, 3D printing technology has made great progress, but its commercialization and marketization process is slow. In t...
