Biofabrication

Products and Services Biofabrication

Manufacturing Methods for Tissue Engineering

  • Photopolymerization of natural derived and artificial polymers for fabrication of arbitrary structures (resolution: 5 µm - < 1 µm)
  • Structuring and perforating of polymeric material for cell seeding (by ablation, drilling, local remelting)
  • Welding and joining of polymeric material for cell seeding. (e.g. customer-oriented combination of previously structured polymeric sheets)

In Vitro Test Systems and Microarrays

  • Local coating of low to high viscous liquids (polymers for biological purposes or for organic electronics, natural derived polymers such as proteins) and solids
  • Contactless handling of very small volumes for coating purposes
  • Contactless positioning of cells
  • Customer-oriented three-dimensional microstructures for the analysis of biomechanical or cell biological purposes
