Our colorFabb_XT, nGen, nGen_FLEX and colorFabb_HT are made from Amphora™ 3D Polymer by Eastman Chemical Company.
Amphora is a range of materials developed and produced by Eastman for FDM 3D printing. With these raw materials colorFabb produces high quality filaments, a co-operation we started in 2013. Many formulations of specialty polyesters have been tested for functionality, printability and safe printing.
All these efforts have lead to 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.
We have now released 4 grades: colorFabb_XT, nGen, nGen_FLEX & colorFabb_HT. You can find more information and documentation on our materials page: https://www.colorfabb.com/data-sheets
nGen has a much wider processing window compared to XT, and is much more hydrolitical stable, so will be easier to print compared to XT.
colorFabb_HT is made with Amphora™ HT5300 and is a low-odor and styrene-free material uniquely suited for advanced 3D printing users, particularly those who need their models to exhibit excellent durability, toughness and high temperature resistance with a Tg of over 100⁰C. colorFabb_HT empowers professional users to create more durable and useful items, making prototyping truly functional. More information can be found on our landing page for colorFabb_HT: https://colorfabb.com/filaments/materials/co-polyester-filaments/colorfabb-ht
Compared to nGen, the XT is much tougher and has a really high melt strength for better bridging. For engineering parts, colorFabb_XT and colorfabb_HT are better suited but its processing window is more narrow
These 3 materials are also food contact compliant.
nGen_Flex is a semi-flexible material with good printability on most 3D printers. With a Shore A hardness level of 95 it will allow you to create a new range of parts and by adjusting infill and perimeter settings it's possible to have full control over the flexibility of your prints.
