FRESH technology can bioprint a 3D extracellular matrix of collagen


Key points from article :

Scientists find a new technique to 3-D bioprint tissue scaffolds out of collagen.

Uses a technique called Freeform Reversible Embedding of Suspended Hydrogels (FRESH).

Couldn’t build an extracellular matrix using existing biofabrication methods until now.

Deposits collagen layer by layer in a support bath, then melts the support bath.

3D printing a full-sized, adult human heart will be possible in the future.

Research by Carnegie Mellon University, published in Science.

A future without the need for organ harvesting and trafficking
