Abstract: A high-precision manufacturing machine used in precision manufacturing processes, such as a 3-D printer, is described. The machine has a frame, a movable platform supported by and movable relative to the frame, on which are mounted one or more platform tool holders for holding one or more tools such as an extruder, a base station that may include one or more bays, each of the bays having a number of base station tool holders, for storing tools that are not in use, and a supporting base, which may be movable relative to the frame, for holding one or more work items to be processed by the tool or tools selected and held by the movable platform.
