Start-up succeeds 3D-printing breakthrough – magic black(!) material allows photopolymerization

Combined with new translucent material, 3D-printing of entire optical systems possibl

13-Oct-2021

Highly precise 3D-structures in black can now be printed using a 2 Photon-Polymerization (2PP) 3D-printing process. This seemed for a long time impossible as non-transmissive (black) materials greatly reduce the polymerization efficiency of the printing process. Now the 2PP-specialist UpNano GmbH ...
