Observational analysis evaluated microstructure and mechanical properties of 316L stainless steel using LPBF, indicating its potential in biomedical implants.
Key Points
Optimized LPBF parameters achieved a tensile strength of 762.83 MPa, surpassing conventional methods.
The study noted 99.97% density and refined microstructure with cellular austenitic grains for 316L stainless steel.
Laser power of 190 W and scanning speed of 700 mm/s were key for enhancing mechanical integrity in implants.
