Effects of laser parameters and scanning strategy on structural and mechanical properties of 3D NiTi implants fabricated with selective laser melting

The additive manufacturing method Selective Laser Melting (SLM) allows the creation of open-porous shape memory structure directly from CAD data. However, during the SLM process, laser parameters and scanning strategy must be carefully selected. In this study, we show that they have a significant effect on geometrical and mechanical properties of NiTi scaffolds for the treatment of large bone defects.
