Amphora 3D Polymers is a specially developed co-polyester just for 3D Printing. It’s toughness and high melt-strength makes it the perfect material for producing fiber reinforced composites, providing the necessary viscosity for 3D printing, combined with a high toughness in the filament and end application

Excellent diameter tolerance
ColorFabb uses sophisticated and highly precise laser measuring systems to check the diameter of the filament in real time during the actual production process. It’s measured over 1000 times per second and this helps guarantee that each spool of filament is produced within tolerance. We can guarantee 0.05mm +/- for our 1.75mm diameter filament, which means you can be rest assured that your printer is extruding the exact amount of material called for.

Climate Controlled Warehouse
STACKER warehouses its filaments in a climate controlled room to protect them heat and moisture which can degrade the life and performance of some filaments.

In-house testing
ColorFabb filaments have been rigorously tested at both STACKER and colorFabb facilities on Stacker 3D printers, and this ensures the best results possible. The colorFabb test lab features a wide range of popular 3D printers, including several STACKER 3D printers. They are continuously testing on 3D printers to ensure the filament is performing in real world situations. If you’re not sure how to print with our materials on your 3D printer, please contact us at or

Material science
ColorFabb was founded as a brand of Helian Polymers, a sister company of Peter Holland which have been active in the master batch and additives for the plastics processing industry. Both companies eat sleep and dream about 3D printing, and our passion drives us to create the best user experience possible.

General Tips

Build platform

colorFabb_XT filament performs best on a heated build platform.

Cooling Fans

The use of cooling fans is not recommended with colorFabb_XT.

3D printers have lots of different types of hot-end which makes it extremely difficult to give universal temperature advice. We feel our temperature advice holds for most 3D printers, but should be considered as a starting point for you to find the temperatures that work in you setup. Don’t be afraid to go either higher or lower than our advised temperatures if you feel your set-up needs this. Please refer back to your printer’s operating manual for safety and temperature specifics.
