Schematic of bioprinting methods. a) Inkjet‐based bioprinting involves the formation of droplets of bioink by generating bubbles in the tip of the printer through thermal, piezoelectric, or acoustic energy. b) Laser‐assisted bioprinting is also based on the generation of droplets of bioink by the incidence of a laser beam on an energy absorbing layer coupled with a donor slide constituted of bioink. The droplets are then recovered on a dedicated platform. c) Extrusion is the most commonly used method; the ink is pressed through the nozzle either with a piston, a screw, or using pneumatic pressure. d) Vat photopolymerization requires the presence of a photoinitiator to cure the polymer loaded with cells.
