Filament 1.75 mm PETG 1 kg by devil design — Dark Copper

devil design PETG 1.75 mm filament, 1 kg spool in Dark Copper is a thermoplastic filament formulated for FDM/FFF 3D printing. The material combines higher impact resistance and chemical resistance than PLA with lower tendency to warp, making it suitable for dimensional parts and visually appealing prints where a copper-like metallic hue is desired. The 1.75 mm diameter is compatible with most consumer and prosumer extruders designed for this filament size, and the 1 kg spool provides a practical balance between print volume and storage.

Advantages

The PETG composition offers improved toughness and layer adhesion compared with standard PLA while retaining easier printability than many engineering polymers. Dark Copper color gives prints a metallic look without using metal-filled compounds, keeping nozzle wear minimal. The filament demonstrates good chemical resistance and reduced moisture sensitivity relative to hygroscopic materials, supporting reliable extrusion and consistent surface finish when stored and dried appropriately.

Suitable for

• Functional prototypes and mechanical parts requiring impact resistance
• Decorative objects and display pieces with a metallic appearance
• Household fixtures and connectors exposed to occasional chemicals or moisture
• Iterative design and parts testing where lower warping is needed

Key specifications

• Material: PETG (polyethylene terephthalate glycol-modified)
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg (net filament weight)
• Color: Dark Copper (metallic copper-like appearance)
• Compatibility: FDM/FFF 3D printers accepting 1.75 mm filament

How to use

Load the 1.75 mm PETG filament into an FDM/FFF printer following the manufacturer’s filament loading procedure. Recommended print settings typically include an extrusion temperature range appropriate for PETG (consult your printer and material guidelines), moderate print speeds, and a heated bed to improve first-layer adhesion. Use a suitable build surface such as PEI, glass with adhesion aid, or a textured plate. Retract and retraction speed should be tuned to reduce stringing; enable part cooling selectively depending on geometry to balance layer adhesion and detail.

Usage recommendations

Store the spool in a dry, sealed container with desiccant when not in use to maintain print quality. Pre-dry filament if it has absorbed moisture before printing. Use a stable nozzle temperature and calibrated extrusion multiplier for accurate dimensions. For the best metallic look, consider post-processing options such as light sanding or clear coating to enhance surface sheen while avoiding abrasive treatments that could wear standard nozzles.
