New 3D Printing Technique for Biomaterials

A new technique could be used to print soft biomaterials that could be used to repair defects in the body. The method offers an alternative to existing techniques that use gels that have been minced to form a slurry bath into which the printed material is injected. Called Freeform Reversible Embedding of Suspended Hydrogels (FRESH), these materials offer many advantages, but friction within the gel medium can distort the printing.
