摘　　要：钛合金是3D打印中使用最广泛的金属材料,具有密度小、比强度高、耐热性好、耐蚀性优异、生物相容性好等优点.不同于传统制造技术, 3D打印技术对粉末材料有着极高的要求,粉末的质量会直接影响3D打印零件的性能.本文从粉末性能入手,阐述了杂质含量、流动性、松装密度等因素对3D打印过程的影响;然后综述了氢化脱氢法、气体雾化法、离心雾化法、等离子雾化法等钛合金粉末制备技术的原理和优缺点;最后结合国内外研究现状,对改善钛合金粉末的方法进行探讨.Titanium alloy is the most widely used metal material in 3D printing,which has the advantages of low density,high specific strength,good heat resistance,excellent corrosion resistance and good biocompatibility. Different from the traditional manufacturing technology,3D printing technology has a very high demand for powder materials,and the quality of powder will directly affect the performance of 3D printing components.The influence of impurity content,fluidity and bulk density in the 3D printing process is described.Then the principle, advantages and disadvantages of hydrogenation and dehydrogenation,gas atomization,centrifugal atomization and plasma atomization are reviewed.Finally,according to the present research situation at home and abroad,methods of improving titanium alloy powder are discussed.
