Bioprinting is the layer-by-layer construction of synthetic tissues or scaffolds. Described herein is a motorized extruder which can precisely extrude and retract extrudate such as bioinks in a compact and rapidly-loadable form-factor. This includes a compact bioprinter using a stepper motor coupled with a threaded shaft to directly move the plunger of an extruder. This pneumatic-mechanical system obviates the needs for pneumatic tubing, rods, or other complex elements of existing designs. The direct drive design further allows for a lighter, smaller gantry that is capable of more precise fabrication of bioprinted constructions. This includes delicate vasculature systems that are beyond limits of existing bioprinting technologies.
