colorFabb nGen Grey Metallic 3D Printer Filament – 1.75mm / 750g Spool

nGen is made from Eastman Amphora™ AM3300 3D polymer. Like colorFabb_XT, it is part of Eastman’s Amphora range of copolyesters for 3D printing.

nGen is a low-odor, styrene-free material uniquely suited for 3D printing enthusiasts, particularly those who need the flexibility to print within a wide processing temperature range. With nGen you will have good flow properties through the printer nozzle—even at lower temperatures than some other polymers require. These properties make nGen more workable at a wider breadth of temperatures, producing reliable results and resulting in less waste.

Look closer… You will see a subtle amount of metallic particles in this material, making it extra special for those who take extra care in their print.

Available from STACKER in 1.75mm and 2.85mm diameter.

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.

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

nGen compound performs best on a heated build platform.

Cooling Fans

The layer bonding with nGen is best when no cooling fans are used.

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.
