Filament PETG 1.75 mm 1 kg spool, devil design — Silver

devil design PETG filament, 1.75 mm diameter on a 1 kg spool in silver is a thermoplastic filament formulated for FDM/FFF 3D printing. PETG offers a balance between printability and mechanical performance: it prints easier than many engineering plastics while providing better toughness, chemical resistance and layer adhesion compared with PLA. This silver PETG is intended for functional prototypes, mechanical parts and visually durable prints where higher impact resistance and dimensional stability are required.

Advantages

PETG filament combines good flow behavior with reduced warping and strong interlayer bonding, enabling reliable printing of medium- to large-sized parts. The material provides increased toughness and chemical resistance compared to PLA, while remaining easier to print than many higher-performance polymers. Silver coloration gives prints a neutral metallic appearance suitable for visible components and aesthetic functional parts.

Suitable for

• Functional prototypes that require improved toughness
• Mechanical parts and brackets exposed to moderate stress
• Household items and tools with chemical resistance needs
• Visually durable models and display pieces with a metallic finish

Key specifications

• Filament diameter: 1.75 mm
• Net weight: 1 kg spool
• Material: PETG (glycol-modified PET)
• Colour: Silver
• Compatibility: FDM/FFF 3D printers designed for 1.75 mm filament

How to use

Load the 1.75 mm PETG filament on a compatible FDM/FFF 3D printer and set the extruder temperature typically between 230–250 °C, depending on printer and nozzle. Use a heated bed set around 70–80 °C to reduce warping and improve first-layer adhesion. Print speeds of 30–60 mm/s are generally effective; adjust retraction distance and speed to minimise stringing. Ensure good part cooling for overhangs while avoiding excessive cooling that could reduce layer adhesion. Follow usual spool handling: keep the filament dry and store in a sealed bag with desiccant when not in use.

Usage recommendations

For best results, calibrate extrusion multiplier and first-layer height for your specific printer and nozzle size. Dry the filament if it shows signs of moisture (brittleness, popping or excessive stringing) by using a filament dryer or oven at low temperature for several hours. Use adhesive aids such as a PEI sheet, glue stick or specialised build surfaces to enhance bed adhesion when printing larger base areas.
