Previously I looked into Arcam’s 3D Metal process. At the time, Arcam’s Ti6Al4V Titanium Alloy seemed the best option.
Today I checked back to Arcam’s materials page and it’s been expanded to include:
- Titanium aluminide
- Inconel (625 & 718)
- Stainless steel (e.g. 17-4)
- Tool steel (e.g. H13)
- Aluminium (e.g. 6061)
- Hard metals (e.g. NiWC)
- Copper (e.g. GRCop-84)
- Beryllium (e.g. AlBeMet)
- Amorphous metals
- Niobium
- Invar
I’m happy to see stainless steel and amorphous metals (although the stainless 17-4 is magnetic).
Soon I will be ordering calibration parts using a variety of 3D printing technologies and materials.
UPDATE: Also check out this amazing polishing technology: Electron Beam Machining. This might be perfect for polishing 3D printed metal pieces.
