Lithography-based Metal Manufacturing (LMM)

LMM-Technology schematic illustration

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.

Characteristic features

  • especially suitable for small and micro parts < 30mm
  • highest precision
  • best surfaces

Technical properties

  • Surface: Ra ~ 2-3 µm
  • Tolerances: ±0.05 mm
  • Layer thickness: 10-60 µm
