‘FRESH’ 3D-bioprinting method enables advanced tissue fabrication

Written by Heather Jones

Researchers from Carnegie Mellon University (PA, USA) recently published a paper in APL Bioengineering providing their perspective on the Freefrom Reversible Embedding of Suspended Hydrogels (FRESH) 3D bioprinting approach, the main feature of which is to involve a yield-stress support bath that holds bioinks in place until they are cured. This platform could significantly advance the ability to fabricate functional adult-size tissues and organs. With the advancement of regenerative therapies and high demand for donor organs, research into 3D bioprinting has grown rapidly in recent years. The most popular 3D printing approach uses bioink – a solution of biological material...
