Three-Dimensional (3D) bioprinting using pneumatic based syringe extrusion has limited precision, stemming from leftover pressure, which leads to leftover extrusion when printing is stopped. This study focused on solving this by powering extrusion with electromechanical pistons. To prevent leftover extrusion, force feedback control was developed but not tested. Furthermore, the developed tool contains three syringes which can be operated separately to enable bioprinting with multiple materials which are mixed in a mixing nozzle. Extrusion tests showed that material mixing was successful, but leftover extrusion was not successfully prevented.
