Today we feature this fully 3D printed gearbox for a NEMA 17 stepper motor with a 4:1 reduction ratio in colorFabb_XT. Designed by Youmagine user Kevin, it utilizes herringbone gears and it performs great.

This print was done using a 0,25mm nozzle width and 0,06mm layerheight on an Ultimaker 2+. colorFabb_XT was used in both light and dark gray to ensure a durable and strong gearbox. The fine detailing meant that the print took a full day to complete. But it’s gears fit together very precisely and there is only minimal play in the system.




colorFabb_XT is made with Amphora AM1800 and was the first material we launched together with Eastman Chemical Company back in 2014.

It has a unique formulation for 3D Printing that features excellent properties : High strength and very high toughness, Odor Neutral processing, High Tg / improved temp. resistance, Styrene free formulation, FDA food contact compliance, BPA (Bisphenol A ) free formulation. It will allow the user to produce 3D printed functional products in a safe way. Eastman Amphora™ 3D polymer is a low-odor, styrene-free choice that is uniquely suited for 3D printing applications. With Amphora, items can be created that are more functional, more durable, more efficient, and attractive.
