Publication number: 20200325430Abstract: A system and method for printing cells in a medium. A multi-dimensional printer, stably constructed of low-mass parts, can include a computer numerically controlled system that can enable motors driving delivery systems. The motors can include encoders that can enable achieving arbitrary resolution. The motors can drive ballscrews to enable linear motion of delivery systems, and the delivery systems can enable printing of a biological material in a pre-selected pattern in a petri dish. The petri dish can accommodate a medium such as a gel, and can further accommodate a vision system that can detect actual position and deflection of the delivery system needle. The printer can accommodate multiple delivery systems and therefore multiple needles of various sizes.Type: ApplicationFiled: July 12, 2017Publication date: October 15, 2020Inventors: Christopher C. Langenfeld, David D. B. Cannan, Dirk A. van der Merwe, Jonathan Parker, John C. Anastasiou, Michael C. Tilley, David Blumberg, JR.
