The laser powder bed fusion is an additive manufacturing process which uses powdered metal in order to create complex shapes, it uses lasers for melting the metal powders. In this a bio-medical grade metal powder is used i.e., SS 316L by using iFusion 150 metal 3D printing machine, it uses Yb – Fibre laser in order to melt the SS 316L powder to the required shapes. The iFusion 150 metal 3D printer uses laser powder bed fusion (LPBF) technology. Mechanical properties like compression strength, micro hardness was examined and found an average of 1340.697 MPa compression strength, 206 BHN hardness values. Their micro structures were examined.
