Paragraph starter

The potential of Selective Laser Melting (SLM) for producing functional end-use metal parts is significant, as noted by Kruth et al. (2010). However, their work highlights that achieving desired microstructures and mechanical properties is contingent upon meticulous optimization of process parameters and build strategies, due to inherent high temperature gradients and densification effects. This underscores the necessity for designers to engage deeply with manufacturing considerations when specifying SLM for critical components.
