a custom made 3 axis cnc gantry controls the position of the print head over a 4’x 8’ printing surface. a fixed cartridge container with an airtight connector allows users to swap out cartridges easily. the end effector consists of a pneumatic system with a pressure regulator that pushes a piston into a cartridge to extrude biopolymer hydrogels through a tip adaptor attached to a nozzle of varying diameters. the size of the nozzle will control the width and precision of the extruded material on the toolpath.
