Carnegie Mellon researchers develop 3D bioprinting technique using collagen

A team of researchers from Carnegie Mellon University has published a paper in Science that details a new technique to 3D bioprint tissue scaffolds out of collagen.
This first-of-its-kind method brings the field of tissue engineering one step closer to being able to 3D print a full-sized, adult human heart, according to a university announcement. View the Science paper HERE.

The technique, known as Freeform Reversible Embedding of Suspended Hydrogels (FRESH), has allowed the researchers to overcome many challenges associated with existing 3D bioprinting methods, and to achieve unprecedented resolution and fidelity using soft and living materials.
 
“What we've shown is that we can print pieces of the heart out of cells and collagen into parts that truly function, like a heart valve or a small beating ventricle,” Adam Feinberg, a professor of biomedical engineering (BME) and materials science & engineering, said in the article. “By using MRI data of a human heart, we were able to accurately reproduce patient-specific anatomical structure and 3D bioprint collagen and human heart cells.” Feinberg is a BMES member.
