Comment on sharing experience with greentec (extrudr) / warping help

I have some experience, but with the GreenTec PRO. I don’t know if you have the same, or if it’s another thing.
The GTP is a composite material, meaning it’s made of at least two different polymers. IIRC it’s PLA (or something very similar) and Lignin, which gives it the heat and mechanical resistance.
I had the experience that it behaves quite the opposite of ABS or other warping prone materials. Usually, slower cooling (enclosure, high bed temp, low fan speed) means less warping.
But GTP was different. I had way less warping when I increased the cooling fan (max) and decreased the bed temp to around 50°C.
It should solidify as soon as it comes out of the nozzle in my experience.

Thank you that’s good insight! I also thought that maybe it would behave more like pla in the cooling and solidifying regards. Changed PLA manifucturer. Settings were a bit too hot for the new spool and had warping on the first larger part.
GreenTec (basic) is like a not so stiff first iteration of their special material mix. It has a high notched and unnotched impact resistance, lower youngs modulus, lower softening temp, and more elongation at break than GTP. You can think of it like the difference of PETG to PET where PETG is the basic Greentec.
