In stock



colorFabb_HT Dark Grey 2.85mm filament is made with Eastman Amphora™ HT5300 3D polymer. It is a low-odour, styrene-free high quality 3D printing material ideal for engineering applications due to its high temperature resistance and toughness.


With a glass transition temperature of 100°C, colorFabb_HT Dark Grey has a high temperature resistance, as well as excellent overhang ability, toughness and chemical resistance. HT3500 is an excellent material to apply to prototypes, models and component parts especially when using in form, fit and function testing. 


Each colorFabb_HT spool contains approx. 700g of filament and is available in 2.85mm and 1.75mm diameters in a range of colours.


Due to the large variation of monitors, video cards, operating systems & Internet browsers and the effects each has on each other, the colours on this page may not exactly match the materials.

Does colorFabb_HT work with all 3D printers?

The colorFabb testlab features a wide range of popular 3D printers. colorFabb continuously test their products on a range of 3D printers to check the quality of the materials produced and to develop exciting new materials.


The following printers are used in the colorFabb lab: Ultimaker Original, Ultimaker Original Dual Extrusion, Ultimaker 2, Makerbot Replicator 2, Delta Tower (E3D hot-end), Felix 20, Leapfrog Creator, Beethefirst.


As such, colorFabb HT can be used for most commercially available leading brands 3D FDM/FFF printers. Please check your specific printer set up, specification and operation of your 3D printer for compatibility.


What qualities does colorFabb_HT have?

colorFabb_HT (Eastman Amphora HT5300 3D Polymer) is a low-odour, styrene-free material specifically developed for 3D printing. HT has a high temperature resistance of 100°C and high toughness. It also displays good bridging capabilities and has chemical resistance making it an ideal material for engineering applications.


What are the processing guidelines for colorFabb_HT?

  • Recommended extruder temperature: 250°C - 285°C

  • Recommended platform temperature: 100°C 120°C

  • Recommended print speed: 30 - 50mm/s 

HT does require adjustments to your print settings, so it is recommended for advanced 3D printing users.


What is the diameter tolerance?

colorFabb use laser measurement systems to check the diameter of their filament real time during production. It’s measured over 1000 times per second and helps guarantee that each spool of colorFabb 3D printing filament is produced within tolerance. colorFabb can guarantee 0.05mm +/- on both 2.85mm and 1.75mm colorFabb 3D printing filament.


Is a heated bed necessary for printing with colorFabb_HT?

Yes, HT works best with a heated bed, with temperatures around 100-120°C.
