Biofabrication

Our range of services

Biofabrication is a current field of work of Fraunhofer ILT which aims at producing living and non-living structures from biomaterials. To construct these structures, the institute employs laser-based printing and structuring processes. The LIFT process (Laser Induced Forward Transfer) offers the best preconditions for the separation of living cells, which can be used, for example, to develop systems for pharmaceutical testing. In addition, scaffolding structures can be fabricated using stereolithographic processes for the research of artificial organs.

The range of services includes contract research on customer-specific tasks, development of biological test systems and the development of machine prototypes for bioprinting.
