Description

Technical field [0001] The invention relates to the field of automatic control, in particular to a pure titanium powder molding method based on selective laser melting technology. Background technique [0002] Because of its excellent mechanical properties and biocompatibility, titanium and its alloys are widely used in clinical medicine bone repair, bone implantation and corresponding processing and manufacturing fields. However, traditional titanium and titanium alloy processing techniques generally have many influencing factors, complicated processes, difficult to accurately process the internal structure, difficulty in one-time net processing, and difficulty in obtaining uniform processing effects. However, the use of selective laser melting technology can better overcome the above problems, and it has flexible manufacturing characteristics that any other processing method cannot match. However, the current powder molding process based on selective laser melting technology h...
