What are the design requirements for sharp surfaces in SLM printing?

Last updated on Apr 02, 2026

If the SLM printed metal part has sharp surface structures, the included angle should be designed to be greater than 20°. Sharp angles smaller than this are prone to chipping, cracking or damage during support removal, sandblasting, packaging and transportation, which will seriously affect the structural integrity and use safety of metal parts.
