Curling comparison - Colorfabb XT vs Esun PETG

Posted · Curling comparison - Colorfabb XT vs Esun PETG


I am quite disappointed with the Colorfabb XT filament, especially at this price point.

There is a lot of curling, especially on overhangs.


Strength-wise, I didn't feel any difference between XT and Esun PETG. It doesn't mean that there are not, simply that I didn't perform tests to actually measure it.

I should have tested the filament instead of relying on the spec sheet and marketing words on the official website before dropping 130 euros (4 rolls).

By the way, I contacted Colorfabb's support and they replied:

The results you have achieved with our _XT material are in line with what I would expect to see for such a model.

So yes, I would say this is an expected result.

It does seem indeed that eSun's PETG handles the dissipation of the heat better in this case.

Until somebody compare the properties of Esun PETG vs Colorfabb XT, I would advise you to stick with Esun PETG. You'll get a much better finish.

I get some curling on overhang corners using eSun PETG, but the fix is easy: slow down the speed to about 20 mm/s for a few layers (and drop the nozzle temp a few degrees).

I've gone through about 45 rolls of their PETG and I keep buying more. It's been consistently good quality for me, and the parts have been strong.

We have not had this experience with warping of ColorFabb XT. To look for warping we use a 6cm x 6cm x 0.8cm (w x d x h ) model (warping is more likely to occur on wide low height models) and we have ended up with a very flat model.


This is not to say that warping will not effect particular models or print environments but it was quite straight forward to achieve this effect.

We cannot comment on the eSun PTEG so we cannot compare. we can only say this warping issue is not our experience.

The printing settings for this print are written on the file.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
