Push the boundaries of MakerBot 3D printing with interchangeable nozzles, custom material print modes, and unlocked advanced print settings. Quickly switch from the reliability of the Smart Extruder+ to the Experimental Extruder to test the limits of your ideas. Print existing PLA materials with the large diameter draft nozzles and dramatically reduce total print time. With a modified thermal core and a more secure thermal barrier tube, the Experimental Extruder was redesigned to make changing nozzles easier.
