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.
