Properties of common 3D bioprinters [57].

	Inkjet bioprinter	Microextrusion bioprinter	Laser-assisted bioprinter
Cost of printer	Low	Medium	High
Printing speed	Fast (1–10,000 droplets/s)	Slow (10–50 μm/s)	Medium (200–1600 mm/s)
Cell density	Low (≤106 cells/mL)	High: cell spheroids	Medium: ≤108 cells/mL
Cell viability	Medium: 85%	Low: 40–80%	High: >95%
