Abstract
The use of intramedullary (IM) pins as implantable devices for the healing of canine femur bone fractures has been documented throughout the last decade. One of the most significant drawbacks of these IM pins is implant displacement from the original position through the proximal end, which is caused by a lower holding power into the proximal end. Although several studies have reported the production of IM pins using conventional manufacturing methods, nothing has been documented on the revolutionary shapes of IM pins for the canine generated by direct metal laser sintering (DMLS) of 17–4 precipitation-hardening (PH) stainless steel (SS). The 3D printing of exceptional IM pin profiles on 17-4PH SS with the DMLS is described in this article. According to the study's findings, the best DMLS settings from a multi-factor optimization viewpoint are laser power (LP) 100W, scan speed (SS) 1200mm/s, and layer thickness (Lt) 0.04mm.
