MakerBot Labs

An experimental platform for engineers and developers to create, build, customize, and collaborate on MakerBot 3D printing solutions.

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

Together, let's push the boundaries of what's possible.

MakerBot Labs

Designed for the advanced user looking to push the limits of what's possible with MakerBot 3D printers. Customize 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

Print existing PLA materials with the included large diameter draft nozzles and dramatically reduce total print time by up to 75%.

Designed to be Hacked

A customizable hardware experience

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.
