Lithography-based Metal Manufacturing (LMM)
Lithography-based Metal Manufacturing (LMM) is a sinter-based AM process characterised by a two-step process. The feedstock is a combination of metal powder and photosensitive polymer binder. This feedstock is applied to a building platform and selectively cross-linked from above by means of mask exposure with UV light. Layer by layer, a green part is created. This green part is then debinded and sintered.
- especially suitable for small and micro parts < 30mm
- highest precision
- best surfaces
- Surface: Ra ~ 2-3 µm
- Tolerances: ±0.05 mm
- Layer thickness: 10-60 µm
