The synchronization among nozzle extrusion, nozzle speed and rotating speed based on 3D vessel bioprinter

3D vessel bioprinter is an emerging and prospect technology, which offers a functional platform to construct the biofabrication. In this paper, we have developed a novel vascular forming device and proposed a theoretical analysis approach to study motion synchronization. Using this bioprinter, we first established a theoretical model to analyze the relationship among nozzle extrusion speed, nozzle speed and servo motor speed; experiments were carried out to verify the theoretical results under all sorts of conditions, the experimental results show agreement with the theoretical results between extrusion speed and nozzle speed, but the experimental result did not agree with the theoretical results between extrusion speed and servo motor speed, with the difference of less than 7%.
