What is the minimum wall thickness requirement for SLM printed metal parts?

Last updated on Apr 02, 2026

The universal minimum printable wall thickness for SLM metal printing is 1mm. For small-sized parts (around 55mm), the wall thickness can be controlled at 1mm; for large parts close to 200200mm, wall thickness needs to be ≥2.5mm to ensure the structural strength and anti-deformation ability of metal parts.
