Hi folks,
I’m exploring Selective Laser Melting (SLM) 3D printing for a small-run production of metal parts—mainly aluminum and stainless steel components for a robotics application. My design includes complex internal structures, which makes traditional machining a pain.
SLM seems ideal on paper, but I’ve never used it before and don’t want to waste money learning through trial and error. I know it's expensive, but I’m more concerned about:
Dimensional accuracy
Surface roughness
Post-processing needs
I came across Sanesra 3D, which lists SLM as one of their advanced services. Has anyone here used their metal printing capabilities? Would love to know how they handle finishing and heat treatment, especially for load-bearing parts.
Also open to general advice on when SLM 3D Printing is worth it versus DMLS or CNC. Are there rules of thumb you follow?
Let’s get a solid thread going for anyone considering metal additive manufacturing seriously. The tech is amazing, but not always plug-and-play.
