Prusament PETG Anthracite Grey 1kg (NFC)

Product Description

Prusament PETG Anthracite Grey 1kg (NFC) is a high-quality PETG filament developed and manufactured directly by Prusa Research in the Czech Republic. Production takes place fully under internal control – every step is measured and tested, allowing us to guarantee extraordinary dimensional accuracy of ±0.02 mm and consistent color for every spool.

The dark, elegant shade Anthracite Grey is perfect for functional prototypes, technical components, mechanical parts, holders, electronics covers, and decorative models where you want to minimize the visibility of fingerprints and minor imperfections.

The NFC spool variant contains an integrated NFC chip, thanks to which compatible Prusa printers can automatically load information about the filament (type, color, production batch, profile) to facilitate print settings.

Key Features

• PETG Material – a combination of toughness and temperature resistance, suitable for functional parts.
• High-precision diameter 1.75 mm ± 0.02 mm for consistent extrusion and high-quality print surface.
• Fill weight ≥ 1 kg of net filament per spool.
• Color Anthracite Grey – a universal technical shade, also suitable for professional use.
• NFC chip in the spool – easy spool identification in compatible Prusa printers.
• Good temperature resistance (approx. 68 °C at 0.45 MPa) – suitable for parts exposed to higher temperatures than PLA.
• Low shrinkage and warping – easy printing without an enclosed chamber.
• High strength and toughness – suitable for mechanically stressed parts.
• Better sandability than PLA – the material is softer and melts less during sanding.
• Made in CZ – original Prusament by Prusa Research / Prusa Polymers.

Recommended Use

PETG is the ideal choice where PLA is no longer thermally or mechanically sufficient, but you don't want the complexity of printing ABS:

• functional prototypes and test parts
• holders, mounts, and assembly jigs
• covers and frames for electronics
• mechanical components for home and workshop use
• interior automotive parts (phone holders, organizers, etc.)
• technical and design models with higher durability

Print Settings (Guideline)

Values are based on recommendations for Prusament PETG and standard profiles in PrusaSlicer:

• Nozzle temperature: 230–250 °C (typically around 240 °C)
• Heatbed temperature: 70–85 °C (recommended approx. 80 °C)
• Recommended surface: smooth, satin, or lightly textured PEI sheet
• Print speed: commonly 40–80 mm/s (slower for detailed models)
• Fan: approx. 30–60% depending on the part type and required strength

For best results, we recommend using the pre-set Prusament PETG profile in PrusaSlicer or another slicer if available.

Tips for Printing PETG

• Bed cleaning: follow the manufacturer's recommendations (for PEI surfaces, use mainly isopropyl alcohol or soap and water, avoid acetone).
• Beware of excessive adhesion: when printing on smooth PEI for a long time, it is advisable to use a separation layer (glue stick, spray) to prevent surface damage.
• Stringing (so-called "hairs"): if it occurs, well-dried filament, fine adjustments to retractions, and nozzle temperature will help. Prusament PETG profiles in PrusaSlicer already have these parameters optimized.
• Storage: keep the spool in a dry place (resealable bags, silica gel); PETG is less prone to moisture than PA or TPU, but for long-term stable results, dryness is always an advantage.

Technical Parameters

Who is Prusament PETG Anthracite Grey for

• Beginners who handle PLA and want to move to a more durable material without the complexity of ABS.
• Advanced users and professionals who require stable quality, manufacturing traceability, and precision across entire spools.
• Owners of Original Prusa printers who want maximum compatibility and utilization of the NFC chip on the spool.

Thanks to the combination of easy printing, high quality, and universal color, Prusament PETG Anthracite Grey 1kg (NFC) is a great choice for everyday functional and aesthetic prints.
