Before packaging, PolyMax™ PETG is dried to ensure the best printing quality and filaments are vacuum sealed to protect the filament from moisture. When not in use PolyMax™ PETG should be stored away from sunlight in the packaged resealable bag.
Like other PETG filaments, PolyMax™ PETG is susceptible to absorbing moisture from the air which can subsequently effect the quality and mechanical properties of the final prints. We recommend storing PolyMax™ PETG in the PolyBox™ or a dry cabinet during printing to prevent moisture absorption which will lower the quality of the print. The PolyBox™ keeps the filament at dry conditions (relative humidity of 15% or less).
If you hear popping sounds and notice that the surface quality of your print is uneven or the color is not consistent, this is a likely indicator that the filament has absorbed too much moisture. Spools of PolyMax™ PETG can be dried in a preheated convection oven at 70˚C for up to 8 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.

Compatibility
PolyMax™ PETG has been engineered with compatibility in mind to print excellently on a wide range of 3D printers. This material requires a heated bed.
Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer.
FAQ
Q: Does PETG print exactly the same as PLA?
A: Most filament types are compared to PLA or ABS when discussing how they print. PETG doesn't print exactly like PLA but it shares more printing characteristics with PLA than it does with ABS. How easy a material is to print will wildly rely on a users hardware and previous experience, but most users find transitioning from PLA to PETG easier than transitioning from PLA to ABS. The key differences between PLA and PETG are a heated bed is very important when printing PETG, optimal printing temperatures are different and the enclosures can be more beneficial when printing some geometries.
Q: Can PETG be printed at large scales without warping?
A: In terms of dimensional stability, PETG is easier to print than high temperature materials like ABS. When using a desktop 3D printer, many large prints that would warp or crack in ABS can often times be printed in PETG without these hassles. Typically PETG can be printed at large scales without requiring an enclosure but this can vary depending on the first layer adhesion and heated bed. For 3D printers that don’t evenly heat the entire bed surface an enclosure can be very helpful. Enclosures can also help to prevent drafts.
Q: Is PolyMax™ PETG a suitable replacement for ABS?
A: Designed to offer a mechanically superior PETG, the toughness and stiffness of this material are comparable to ABS. Infact Polymakers nano-reinforcement technology offers some significant improvements, with PolyMax™ PETG producing impact resistant parts that outperform many ABS filaments on the market. Combining excellent printability and mechanical performance, PolyMax™ PETG is an excellent alternative t ABS.
Q: Does Polymakers Nano-reinforcement technology impact printability?
A: The nano-reinforcement of PolyMax™ PETG is NOT a fiber reinforcement, so customers can confidently print this material with a standard brass nozzle. The good mechanical strength of PolyMax™ PETG is achieved with no compromise in printing quality or usability.
