  • Recommended platform temperature: 60-70°C

  • Recommended print speed: 35 - 50mm/s 


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_XT?

XT works best with a heated bed, with temperatures around 60-70°C. For printing on a non-heated bed, follow colorFabb’s hints and tips for 3D printing in colorFabb_XT.


Is it necessary to coat the build platform prior to a print?

We would recommend using your normal adhesion, as you would for any other print, for example a little glue stick on an Ultimaker 2.


Can colorFabb_XT be used as support material?

Yes, colorFabb works well in prints as support material and can be removed once the print is complete.


Are there any additional printing tips for colorFabb_XT?

Yes, colorFabb have created an excellent guide for 3D printing in XT.


Is colorFabb_XT food or medical grade?

colorFabb_XT is FDA food contact compliant.
