Vibratory finishing on SLM-printed hip stem implant
The primary objective of this study is to investigate the viability of utilizing vibratory finishing to post process SLM printed parts to standards desired for Ti64 hip stem implants. SLM printed parts are able to customize an implant best suited to the patient to be printed, heaping various long-te...
