3D Printing materials.
The researchers for Carnegie Mellon University developed photo-cross-linkable and temperature-sensitive bio-ink for 3D bioprinting.
According to researchers at Carnegie Mellon University in Pittsburgh,¨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. Freeform Reversible Embedding of Suspended Hydrogels (FRESH) is an embedded printing approach that solves this problem by extruding bioinks within a yield-stress support bath that holds the bioinks in place until cured.¨
In accordance with co-author Daniel J. Shiwarski, “fabrication technique for [human] tissue engineering and regenerative medicine,” its use has been limited “by the challenge of printing soft … materials in the air.¨
