Abstract:
A process for producing a 3D tissue culture model by (a) printing a drop of bio-ink to a substrate; (b) printing a drop en.) of activator to the drop of bio-ink to form a hydrogel droplet; (c) repeating steps (a) and (b) in any order to form a hydrogel mold adapted to receive a drop containing cells; (d) printing a drop containing cells to the hydrogel mold; and (e) repeating steps (a) and (b) in any order to form a 3D tissue culture model comprising the cells encapsulated in the hydrogel mold.

Claim (Index 8):
