Applications of stem cells and bioprinting for potential treatment of diabetes

Figure 2 Classification of bioprinting techniques. Three major classifications of bioprinting modalities are A: Inkjet-based printing, which air-pressure pulses that force droplets from nozzle by heating up the printhead; B: Exzrusion-based printing,using pneumatic or mechanical dispensing systems for extruding continuous beads of materials and/or cells; C: Laser-based bioprinting that uses lasers focused on an absorbing substrate for generating pressure that compels the bioink to be extruded onto a collector substrate.
