Abstract

The invention relates to the technical field of 3D printing, and proposes a 3D printing composite material suitable for medical treatment and aviation, comprising the following components in parts by weight: 60-70 parts of TPEE, 1-5 parts of TPU, 20-30 parts of PLA, 0.5-1 part of flat, 1-3 parts of modified nano titanium dioxide. Through the above technical solutions, the problem that the mechanical properties of 3D printing materials in the prior art are not compatible with the biological skin adhesion is solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular, to a 3D printing composite material suitable for medical treatment and aviation and a preparation method thereof. Background technique [0002] 3D printing is mainly composed of software, materials and equipment. It is based on the computer three-dimensional design model. Through the software layered discrete and numerical control forming system, metal powder, ceramic powder, plastic, Special materials such as cells and tissues are stacked and bonded layer by layer, and finally superimposed to form a solid product. In recent years, 3D printing technology has been a research hotspot in various fields, but its development time is still short, and there are still some imperfections in various aspects, and its limited types of consumables and insufficient performance are an important problem faced by 3D printing. [0003] At present, there are very few 3D printing materials on the...
