Last month, the 44th Annual Conference of the European Society for Artificial Organs was held in Vienna. The conference offered a diverse program with impressive talks and fascinating posters. Andreas Blaeser, scientist at RWTH Aachen and CEO of Black Drop Biodrucker GmbH, demonstrated recent progress in 3D-bioprinting research. In the session Tissue Engineering & Regenerative Medicine, Blaeser, introduced a novel Drop-on-Demand bioprinting approach for generation of capillary-like networks. The presented technique holds great promise to facilitate fabrication of vascularized organs-on-a-chip in the near future.
