3D打印生物医用钛合金粉末研究进展

Advances in the Preparation of 3D Printed Biomedical Titanium Alloy Powder

钛合金具有优异的力学性能和良好的生物相容性,在硬组织植入方面应用广泛。介绍了目前常用钛合金粉末制备方法(气体雾化法、等离子旋转电极法、等离子体雾化法等)的原理和工艺特点,比较了不同方法制备出粉末的性能特点,以期为3D打印制造出性能优异的医用钛合金种植体提供思路。

Titanium alloys have excellent mechanical properties and good biocompatibility,widely used in hard tissue implants.The paper introduces the principles and process characteristics of titanium alloy powder preparation methods commonly used now(including gas atomization,plasma rotary electrode method and plasma atomization method)and compares the performance characteristics of the powder made by different methods,aiming to provide a new avenue for 3D printing to produce medical titanium alloy implants with improved performance.
