Abstract

The invention discloses a medical three-dimensional printing alloy material and a preparation method thereof. The medical alloy components and their mass percentages for three-dimensional printing are: 6~12wt.%Fe, 1~11wt.%Zn, 0.5~4wt. %Y, 0.01~0.07wt.%Cu, 0.5~3 wt.%Ca, 0.1~2.5wt.%Mn, 0.1~1wt.%Zr, and the balance is Mg. The preparation method is as follows: after designing the composition, the raw materials are made into spherical powder, and the metal powder is fully mixed, the mixed raw material powder is sintered and solid solution heat treated, and then the light alloy spherical powder is obtained through mechanical grinding and alloying. The invention is a multi-component degradable alloy material composed of human nutritional elements with complete biological safety, and has excellent flame retardancy, powder shape and particle size are easy to control, and can be used in the field of medical degradable implant materials and three-dimensional printing All have important application potential and good application prospects.

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...
