Mask projection No „hatching“ but „texturing“

• Short building times through mask projection of a sequence ofcomplete layers:

• Exposure control at overhangs

Photopolymerisation through a „contact window“• Glas plate as polymerisation and reference surface

• no material leveling necessary and no coater / „doctor blade“ required

• unsensitive against quakes/vibrations

• no oxygen inhibition in the polymerisation layer
