• Availability of hydrogel-based biomaterials that can serve as a cell delivery "bio-ink"
  • A cell-laden "bio-ink" in the cartridge can be precisely dispensed by controlling actuating pressure or piston of the syringe pump
  • "Bio-ink" provides suitable printability with high resolution capability
  • "Bio-ink" provides mechanical support, cell-specific cues, and negligible cytotoxicity.
  • Advances in the field of suitable cell-compatible hydrogel-based "Bio-ink" are necessary for the long-term success of 3-D bioprinting
