Filament Prusa PETG 1.75 mm 1 kg spool — Anthracite Grey

Prusa PETG 1.75 mm filament on a 1 kg spool in Anthracite Grey is a thermoplastic extrusion material formulated for FDM/FFF 3D printing. It is intended for printers that accept 1.75 mm filament and provides a balance of mechanical strength, chemical resistance and dimensional stability. The filament is wound on a standard spool and supplied ready for loading; to preserve print quality, store the spool in a dry environment and use printer settings recommended for PETG materials.

Advantages

Prusa PETG combines higher impact resistance and better layer adhesion than many PLA grades while remaining easier to print than some engineering plastics. The Anthracite Grey color offers a neutral, professional-looking surface that hides minor blemishes and is suitable for functional prototypes and finished parts. The filament's consistent diameter and extrusion behavior support reliable printing with reduced clogging and stringing when using proper temperature and retraction settings.

Suitable for

• Functional prototypes and end-use parts requiring toughness and moderate heat resistance
• Mechanical components such as brackets, clips and gears
• Containers, enclosures and fixtures that benefit from chemical resistance
• Visual prototypes and models where a neutral grey finish is desired

Key specifications

• Material: PETG (glycol-modified polyethylene terephthalate)
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg of filament
• Color: Anthracite Grey
• Typical printing temperature range: use PETG-recommended nozzle temperatures (see printer guidelines)
• Recommended printer type: FDM/FFF printers compatible with 1.75 mm filament

How to use

Load the Prusa PETG filament onto a printer configured for 1.75 mm material and follow the printer manufacturer's instructions for filament loading and filament path. Set nozzle and bed temperatures according to your printer and the PETG temperature range; allow the first layer to adhere steadily by adjusting bed leveling and initial print speed. Use appropriate retraction distance and speed to minimise stringing, and print with a cooled but not overly aggressive part cooling fan to aid layer bonding. After printing, allow parts to cool gradually before removal to reduce warping.

Usage recommendations

Store the spool in a sealed, low-humidity environment or desiccant bag to prevent moisture uptake. If filament has absorbed moisture, dry according to filament drying guidelines before printing. Fine-tune extrusion multiplier and temperature for optimal surface finish and dimensional accuracy on your specific printer.
