ColorFabb - XT - 750grs 1.75mm
The ColorFabb_XT range is a special amorphous copolyester with a Tg of 75 C. So you can use this up to 70 degrees C. Toughness is high. Elongation at break = 50% (yield). In comparison, the normal Colorfabb PLA range has a elongation of approx 10% at yield, but has very good layer adhesion properties and is a bit softer compared to standard PLA. Both qualities have minimum warping tendencies.
In addition to this, ColorFabb XT is very transparent and odourless compared to ABS.
Colourfabb XT is eXtra tough, eXtra resistant and eXtra transparent.
Printing with Colorfabb XT - please read this:
In-house testing showed that ColorFabb_XT likes to be printed at a higher temperature then PLA to increase flow and improve the bonding of layers. On our printers we’ve printed objects in the range of 225-240 ºC, depending on the chosen print speed. (we recommend 240ºC~245ºC for accelerated prints on Makerbot printers)
Switching back to PLA or another material is usually done by ‘purging’ the hot-end of XT material. Heating up the hot-end to 240 ºC and feeding through new material will purge the hotend of XT. Another method would be to insert filament manually in the hotend (while hot) and retracting it immediately. XT will stick to the end of the filament which can then be cut off. Repeat this several times to completely clean out the hot-end.
When using this plastic with your printer, simply choose "PLA" as the printing material in the printer software. For optimal results, you may need to adjust the printing temperature, depending on the colour you are using.
Each spool comes with a label on the packing that indicates the recommended printing temperature for that colour.
