Filament spool 1 kg PETG Red – devil design, 1.75 mm (Ø 20 cm)

Filament spool 1 kg PETG Red – devil design, 1.75 mm (Ø 20 cm) is a 1 kg reel of PETG 3D printing filament in red, manufactured by devil design. Made from Polyethylene Terephthalate Glycol (PETG), this filament has a nominal diameter of 1.75 mm and is wound on a spool with an approximate outer diameter of 20 cm. The material is supplied vacuum packed together with a desiccant to reduce moisture uptake during storage. PETG combines the strength of PET with improved toughness and modest flexibility, making it suitable for a wide range of FDM/FFF printing tasks. The spool is designed for universal compatibility with FDM/FFF printers from various manufacturers.

Advantages

PETG filament provides a balance of strength, impact resistance and ease of printing. The material is less brittle than PLA and offers better layer adhesion and chemical resistance compared with standard PLA, while remaining easier to print than many engineering polymers. The 1.75 mm diameter is a common industry standard that ensures consistent feeding and extrusion in most hobbyist and professional desktop FDM/FFF printers. Vacuum packing with a moisture absorber helps preserve filament quality and reduce printing issues related to filament moisture.

Suitable for

• Functional prototypes and mechanical parts requiring toughness
• Enclosures, brackets and mounts where impact resistance is important
• Decorative prints and colored parts with visible surface finish
• Small production runs and one-off items printed on desktop FDM/FFF machines

How to use

Before use, open the vacuum pack and allow the filament to acclimatize briefly if stored in a cold environment. Load the 1.75 mm filament onto the printer spool holder ensuring smooth free rotation, thread the filament through the extruder and perform a filament load routine to verify consistent extrusion. Recommended printing parameters depend on the specific printer and nozzle, but typical PETG settings are a nozzle temperature in the range of 230–250°C and a heated bed temperature between 60–80°C. Use a moderate print speed and enable retraction settings suitable for PETG to reduce stringing. Store unused filament in a dry container with desiccant to preserve quality.

Usage recommendations

For improved adhesion, use a clean heated bed, an adhesive aid (such as glue stick or PEI sheet) and a suitable first layer height. If surface gloss or clarity is important, adjust cooling and print speed; lower fan settings typically yield better layer bonding and surface finish for PETG. Dry the filament in a filament dryer or low-temperature oven if prints show excessive bubbling or poor extrusion due to moisture.
