Also called: DMLS, SLM, binder jetting
Metal 3D printing builds parts from metal powder, fused with a laser (DMLS or SLM) or bonded and then sintered in a furnace (binder jetting). It makes complex metal shapes that can't be machined, but it's the most expensive type of printing.
Good for
- Complex metal parts
- Lightweight aerospace and motorsport parts
- Custom tooling
- Parts impossible to machine
How it works
- You upload your file and describe the use.
- The shop reviews the design for metal printing.
- Parts are printed, then usually heat-treated.
- Supports are removed and the part may be machined or polished for final fit and finish.

Common questions
Should I print in plastic first? Often, yes. A low-cost plastic print lets you check size and fit before paying for metal.
