‘Harnessing Macromolecular Chemistry for 3D Bioprinting of Tissues’

 3D Bioprinting requires specialised bioinks that is able to be printed but also protect the cells during the printing process. These bioinks are often biomaterials with specific rheological properties that allows spatial extrusion in a layer-by-layer manner, but also being cyto-compatible to support cellular viability and function. This lecture will cover the different design criteria required for bioinks, as well as the variety of materials being employed to manufacture these bioinks. Specific focus will be placed on the various chemistries used to synthesise polymers, photo-initiating systems to crosslink the polymers, as well as strategies to maintain bioprinted constructs’ stability.  Moreover, these chemistries and strategies will also be compared between different biofabrication platforms, including extrusion and lithography-based bioprinting technologies. The versatility of these materials and crosslinking chemistries allows the generation of different tissue analogues including cartilage, bone and blood vessels.
