Filament spool PETG 1.75 mm 1 kg — devil design (Copper)

devil design PETG filament, 1.75 mm diameter on a 1 kg spool in Copper color, is formulated for FDM/FFF 3D printers that accept 1.75 mm filament. PETG offers a balance of tensile strength and moderate flexibility with reliable layer adhesion and improved chemical resistance compared to standard PLA. The metallic copper appearance makes this filament suitable for parts where a copper-like finish is desired without post-plating, while retaining practicality for functional prints and prototypes.

Advantages

This filament combines mechanical durability and ease of printing: good interlayer bonding reduces delamination risk, and the material’s toughness allows for functional components that withstand mechanical stress. The 1.75 mm diameter provides consistent extrusion on most consumer and prosumer extruders, and the 1 kg spool size supports small to medium production runs. The copper color provides an attractive metallic look directly from the printer, reducing the need for painting or additional surface treatment for decorative items.

Suitable for

• Functional prototypes and mechanical parts requiring strength and some flexibility
• Decorative objects and display items with a copper-like finish
• Household fixtures, brackets and enclosures exposed to moderate chemical contact
• Small-batch production and replacement parts for hobbyist and workshop use

Key specifications

• Material: PETG (glycol-modified polyethylene terephthalate)
• Nominal diameter: 1.75 mm
• Spool weight: 1 kg of filament
• Color: Copper (metallic appearance)
• Recommended print bed adhesion: heated bed advised
• Compatibility: FDM/FFF 3D printers supporting 1.75 mm filament

How to use

Load the 1.75 mm PETG filament onto a compatible extruder and set printer parameters according to manufacturer guidance for PETG: typically a higher nozzle temperature than PLA and a heated bed to improve adhesion and reduce warping. Calibrate extrusion multiplier and retraction settings to minimise stringing while maintaining consistent flow. Print cooling should be moderate; excessive part cooling can reduce layer adhesion. After printing, allow parts to cool gradually on the bed to avoid deformation.

Usage recommendations

For optimal results, start with manufacturer-recommended print temperatures and adjust in 5–10 °C increments to refine surface finish and interlayer bonding. Use a heated bed (around 60–80 °C) and consider a textured or treated build surface for improved adhesion. Reduce retraction distance and increase retraction speed if stringing appears, and store spools in a dry environment or sealed container with desiccant to prevent moisture uptake that can affect print quality.
