After drying some filament spools, you can put them into sealed plastic bags or boxes to keep them dry. Conclusion. It is a good idea to dry PETG filaments if you store them in a humid environment. The less water they contain, the better the printing quality will be. Drying filaments don’t cost too much, and it’s easy to do.
how to dry your filament | 3d print beginner
How to dry PETG? I recommend drying your PETG at a temperature of 60C-65C for at least 4 hours. ABS. ABS (or acrylonitrile butadiene styrene) was the most popular filament used in the beginning of 3D printing. It is still used because it offers good temperature resistance, but it has a few drawbacks.

But I think that temperature also plays in drying, it always helps if you get molecules moving faster. I once found these somewhere, and from what I tested they work. You basically set temperature as high as possible before glass transition. PLA - [email protected]°C. ABS - [email protected]°C. PETG - [email protected]°C. NYLON - [email protected]°C.

plastic petg injection molding processing conditions
Plastic PETG Injection Molding Processing Conditions. Drying is essential for PETG prior to injection molding. The moisture level must be below 0.04%. Drying temperature is not to exceed 66°C [150°F]. Drying at approximately 65°C [149°F] for 4 hours is recommended. PETGs (or copolyesters) are glycol-modified PETs.
drying times and temps in dehydrator – general discussion ...
Initially, I dried PETG at 149F (65C), but after some 24 hour long tests showed my PETG is fine at 158F, I just dry PETG at 158F. Comes out fine and lets me process PETG at same time as polycarbonate Polycarbonate 158F (70C) x 10 to 20 hours -- Makes a huge difference in stringing especially if you plan to print at high end of temperature range for better fusion.
pet drying : plastics technology
PET must be dry just prior to processing, and amorphous PET requires crystallizing prior to drying so that the particles don’t stick together as they go though glass transition. Hydrolysis can occur due to moisture and this often can be seen as a reduction in the IV (Intrinsic Viscosity) of the product. PET is "semi-crystalline".
