MakerBot Labs was born out of feedback from advanced users looking to tap their innovative spirit and expand their 3D printing experience.



The MakerBot Experimental Extruder has been designed for the MakerBot Replicator, Replicator+, Replicator Mini, Replicator Mini+ and the Replicator Z18.




Customize Your 3D Printing Experience

This extruder is for the advanced user who wants to push the limits of what’s possible on their MakerBot 3D Printer. With the MakerBot Experimental Extruder you will be able to customise your 3D printing experience with a modifiable hardware design and interchangeable nozzles.


The Experimental Extruder is an experimental product and is not covered under warranty or MakerCare.


Creative Flexibility with a Range of Materials

Push the boundaries of MakerBot 3D printing with interchangeable nozzles and unlocked access to custom print modes for full experimental freedom.



Freedom to Switch from Production to Sandbox

Quickly switch from the reliability of the Smart Extruder+ to the Experimental Extruder to test the limits of your ideas. 



Drafting for Speed

With the MakerBot Experimental Extruder you will be able to print existing PLA materials with the included large diameter draft nozzles and dramatically reduce total print time by up to 75%.



Designed to Be Customized

With a modified thermal core and a more secure thermal barrier tube, the Experimental Extruder was redesigned to make changing nozzles easier. Download and print the Experimental Extruder Jig to provide a more stable platform.
