Problems solved by technology

[0005] In recent years, 3D printing technology has been widely used in the field of clinical medicine, because it can quickly, accurately and targetedly prepare personalized biomedical materials based on the different needs of different patients, and at the same time, it can also precisely control the materials. However, in the application process of this technology in medical materials, due to the biocompatibility problems of some raw materials in the printing process, the required products cannot be printed, which restricts its application in the clinical field

Embodiment 1

[0023] A 3D printing material with good biocompatibility, the weight percentage composition of the 3D printing material is as follows:

[0024] Tantalum, niobium, titanium alloy nanoclusters 0.5%;

[0025] Ti-13Mo-7Zr-3Fe alloy nanoclusters 0.5%;

[0026] Modified bisphenol A glycidyl methacrylate 20%;

[0027] Ethoxylated bisphenol A glycidyl methacrylate 75%;

[0028] Photoinitiator OMBP 4%.

[0029] The materials were prepared according to the above proportions in Example 1. Under the water temperature of 50°C, the materials were sonicated with an ultrasonic cleaner for 10 minutes, and then placed in a homogenizer to stir evenly to obtain a 3D printing material with good biocompatibility. performance.

Embodiment 2

[0031] 3D printing material with good biocompatibility, the weight percentage of the 3D printing material is as follows:

[0032] Tantalum, niobium, titanium alloy nanoclusters 1%;

Abstract

The invention discloses a 3D printing material with good biocompatibility. The material complies with the USP VI level standard, and the weight percentage is as follows: tantalum, niobium, titanium alloy nanocluster 0.5%-1.5%, Ti-13Mo-7Zr-3Fe Alloy nanocluster 0.2%-2.0%, low-migration biocompatible active compound 55%-90%, low-migration biocompatible photoinitiator 3%-9%. The present invention develops 3D printing materials with good biocompatibility, and adds inert tantalum, niobium, titanium alloy nanoclusters, and Ti‑13Mo‑7Zr‑3Fe alloy nanoclusters to endow the 3D printing materials with good biocompatibility, satisfying more Many clinical applications.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing material with good biocompatibility. Background technique [0002] Biocompatibility refers to a material that causes an appropriate response in a specific part of the body; according to the interpretation of the International Organization for Standardization Conference, biocompatibility refers to a property of living organisms that respond to inactive materials, generally referring to materials Compatibility with the host; after the biological material is implanted into the human body, it will have an impact and effect on the specific biological tissue environment, and the biological tissue will affect the biological [0003] The material also has an influence and effect, and the cycle of the two continues until equilibrium is reached or the implant is removed. [0004] 3D printing technology has now entered an era of rapid development. 3D printing has been giv...
