Abstract — 3D printing has recently emerged as a real game changer in everyday life applications and high-end technologies across several areas. Among the plethora of additive manufacturing technologies, this talk summarizes the novel techniques available within the BioDiscovery 3D Printer from Regenhu, recently acquired within the European FET-OPEN project NeuroStimSpinal. This 3D printer presents 3 pneumatic dispensing-based extrusion heads and gathers several technologies.

Multi-material devices can be printed by combining slurry, solution extrusion, microvalve based printing, electrohydrodynamic jet printing and melt electrowriting. All these technologies can further integrate UV-assisted curing. Targeted applications go from flexible electronics to high resolution sensors, energy harvesting, micro-optical components, and regenerative medicine. The system is equipped with a class II biosafety cabinet, suitable for bioinks to print anatomical size acellular devices but also scaffolding strategies with precise spatial control of cell deposition within the constructs.

Keywords— 3D printing; extrusion based bioprinting; melt electrowriting; electrohydrodynamic jet printing
