Figure Legend:
A schematic diagram of the three-dimensional tissue printing process. The chamber is filled with the sodium alginate and collagen solution mixture. The alginate is known to cross-link in the presence of CaCl2 to form a biodegradable hydrogel scaffold. The ink cartridge, filled with the cell print suspension in 0.1MCaCl2 solution, ejects cell-CaCl2 drops, which immediately gel upon contact with alginate. The gel droplet is placed at target sites layer-by-layer onto the platform, resulting in the construction of 3D structures. The platform is programed to submerge into the fresh uncross-linked solution that maintains hydration of the gelled constructs while providing a new interface for the next layer.
