Study: New approach to 3D printing of human tissue closer to reality
Feb. 16 (UPI) -- A new approach to 3D bioprinting has overcome the shortcomings associated with earlier versions of the technology, bringing the creation of human tissue and organs one step closer to reality, researchers at Carnegie Mellon University in Pittsburgh said Tuesday. The approach, called Freefrom Reversible Embedding of Suspended Hydrogels, corrects problems caused by gravity in the bioinks used to "print" human tissue, according to the researchers in an article published by the journal APL Bioengineering.

Shiwarski told UPI. H...
