MakerBot Labs was born out of feedback from advanced users looking to tap their innovative spirit and expand their3D printing experience.


The MakerBot Labs Experimental Extruder

The Experimental Extruder was designed for the advanced user looking to push the limits of what’s possible with MakerBot 3D printers. Customise your 3D printing expeience with a modifiable hardware design and interchangeable nozzles.*





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


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.
