PET filament settings - XT ColorFabb - MadeSolid PET+

[MidWestMade]

Just picked up some of ColorFabb’s “XT” filament which, in the description, is a PET material. I currently have PET+ spools from MadeSolid. Reviews and testimonials for the XT are saying use a cooling fan while printing, while the PET+ recommended settings are similar to ABS (with enclosure). My PET+ prints are a bit stringy, so I am wondering what settings people are using for the best results ?

Hey Nate,

I usually print my XT quite toasty, on 260°C hotend and 70°C bed temps. Taking it a little slower is also a good idea, above 40mm/s the material starts to excessively glob up behind/around the nozzle. Slower retracts should also make your prints less stringy.

Let me know, if this improved things for you.

Sincerely,

Jonas

I print my PETG @ 240-250°C and 50-60mm/s and 100° C Printbead temperature. My extusion multiplyer is 1.10. Everything is fine until now.

Hey Nate,

Adam from MadeSolid here. I did some testing with XT at 245C like it recommended on their site and it did not come out very well at all. I then printed with PET+ and, well, you can see the results. It was a smaller spool holder. Something went very wrong on the XT print…

Hi Adam,

Gijs from colorFabb here. We can definitely help you find better settings for printing with our XT material, I imagine it’s quite different from PET+. Just let me know which 3d printer you’re using and if you could share the STL file that would be great!

best,
Gijs
