How it works:
A high-power laser selectively melts thin layers of metal powder spread over a build plate. The laser scans in the XY plane, fusing particles together, while un-melted powder supports the structure. As shown in the diagram, layers build up vertically in Z until the part is complete. Loose powder is then removed and can be reused.
Where it’s used:
SLM is used in aerospace, automotive, and medical industries for lightweight components, custom implants, and complex geometries that traditional machining can't achieve. It's common in tooling, robotics, and performance parts where strength-to-weight ratio and material quality are critical. SLM also enables on-demand production of end-use parts with reduced lead times.
