Abstract

A 3D-printed biomaterial is described that comprises a double-networked hydrogel comprising gelatin or gelatin methacryloyl and alginate, and cells. Methods of making the 3D-printed biomaterial by extruding a hydrogel comprising gelatin or gelatin methacryloyl and alginate from a 3D-printer and converting the hydrogel to a double-networked hydrogel by cross-linking the gelatin with a first cross-linking method and cross-linking the alginate with a second cross-linking method are also described. Methods of treating a damaged or diseased blood vessel and testing vasoactive drugs using 3D-printed blood vessels are also described.
