摘 要：

A chemical etching method for improving the surface smoothness of 3D printed titanium and titanium alloy articles is described. The titanium surface is

produced via additive manufacturing. The method of improving the surface of the articles is achieved through immersion of the articles in an etching solution where the etching solution is maintained at a temperature of 2-85 oC. The etching

solution comprises 20-45 v/v% nitric acid, 4-14 wt% ammonium bifluoride

(ammonium hydrogen fluoride). Electron beam (EB) manufacturing or selective laser sintering (SLS) is used to produce the article and it may be etched until between 125-750µm of surface material has been removed. 主权项：
