Overture Rock PETG 3D Printer Filament 1.75mm

PETG has notable advantages in heat resistance and chemical resistance. It also provides higher impact strength and is generally priced lower than Overture PLA, offering a cost-effective option for durable prints.

Yes, PETG is sensitive to moisture, so we recommend drying under 65°C (149°F) for 7 hours. Avoid extended drying times, as this can lead to the filament becoming brittle and unsuitable for printing. For storage, keep it in a sealed container with desiccants to maintain low humidity levels.

Use the cooling fan to improve surface quality by reducing stringing, but be aware that it may weaken layer adhesion. Conversely, not using a fan can enhance layer adhesion and strength. Whatever you choose, the initial layer should have minimal cooling (around 0% or very low) to ensure good bed adhesion.

If you experience warping or poor bed adhesion with PETG, try increasing the bed temperature to around 70-80°C (158-176°F) and use a suitable bed surface like glass or PEI, possibly applying a light adhesive like glue stick or hairspray. Ensure the initial layer height is calibrated correctly and print at a slower speed for the first layers. It may also help to reduce or turn off the cooling fan during the first few layers and check that the nozzle height is not too high. These adjustments should improve bed adhesion and reduce warping.

Overture PETG exhibits good heat resistance, with a Vicat Softening Temperature of 85.1°C, according to ISO 306 and GB/T 1633 standards. While suitable for many applications, it's important to consider that it may not perform as well as higher-temperature resistant materials.

For reference, the Vicat Softening Temperatures of other engineering filaments are as follows:

• ABS: 103.4°C
• ASA 106.2°C
• PC Professional: 110.3°C
• Easy Nylon: 181.2°C

Brittle filament is a sign of moisture absorption. We recommend drying the filament and storing it in an airtight bag or container.Please refer to the“Drying Time”table for suggested drying times.
