Effect of polyamide-12 material compositions on mechanical properties and surface morphology of SLS 3D printed part

Despite the fact that many 3D printed products have been developed, there are still issues with the printed product’s physical properties and surface morphology. This study examines the effects of significant Selective Laser Sintering (SLS) 3D printer parameters on the material strength of Polyamide...

Furthermore, the SEM results showed that the specimens were partially melted with a significant amount of PA-12 powder before being sintered and coalesced.
