Abstract

Novel Materials and Strategies For Extrusion Bioprinting

Michael Gelinsky, Professor and Head, Technische Universität Dresden

Three dimensional bioprinting is a fast developing field of research. Beside other technologies, extrusion printing (direct printing/3D plotting) is one of the most common techniques for bioprinting. It is based on the controlled deposition of cells, suspended in hydrogels of suitable viscosity. The combination of hydrogel and cells is called bioink. Extrusion bioprinting therefore directly leads to tissue-like constructs, consisting of cells and an extracellular matrix-like structure which might be advantageous especially for musculoskeletal tissues. The lecture will describe some recent developments in the field of novel bioinks, co-printing of bioinks and self-setting mineral bone cements as well as a nanoparticle-based sensor system which allows local on-line analysis of oxygen concentration in 3D bioprinted constructs.
