Advanced Firmware and Hardware for Multiscale and Multimaterial Bioprinting

Bioprinting allows precise deposition of multiple materials at different scale lengths, to fabricate complex scaffolds which mimic the natural tissue cues. A novel trend in the design of 3D Bioprinters is the integration of multiple fabrication techniques into the same machine, to speed-up the scaffold fabrication process and increase the scaffold functionalities. Even if multi-technique bioprinters have reached the market, their implementation is far from being optimized. In this work we present a novel printing platform with high accuracy that implements two of the most commonly used Bioprinting strategies, namely piston-actuated extrusion and thermal drop-on-demand inkjet. Here we firstly present a method to find the optimal printing parameters, and then proof-of-concept printed shapes to validate the developed platform.
