Prusament PETG Anthracite Grey 900g Refill (NFC Compatible)

Prusament PETG Anthracite Grey 900g Refill (NFC Compatible)

Prusament PETG Anthracite Grey is a high-quality PETG filament from Prusa Research in a universal anthracite grey shade, ideal for technical parts, functional prototypes, and design models. The 900g Refill (NFC Compatible) variant is wound on a cardboard core and is intended to be mounted on original Prusament NFC spools with OpenPrintTag technology.

The Refill solution saves money and the environment – instead of a new plastic spool, you use your existing Prusament spool, while the NFC tag stores key material data directly on the label and allows it to be read by compatible devices and applications.

Main advantages and use

• Universal anthracite grey color – an elegant technical shade suitable for functional parts, covers, brackets, mechanical components, and design models.
• Durable PETG material – a combination of good strength, toughness, and temperature resistance for everyday use.
• 900g refill for NFC spools – the refill is wound on a cardboard core and is compatible with the new type of Prusament NFC spools, so after transferring the sides, you get a "smart" spool.
• OpenPrintTag NFC standard – the NFC tag on the spool (which you refill) stores material data locally, without dependence on the cloud and locked ecosystems.
• More ecological solution – less plastic waste thanks to the repeated use of Prusament spools.
• High winding quality and tolerance – excellent diameter consistency and precise winding minimize jams and increase the reliability of long prints.

Typical use:

• functional prototypes and mechanical parts
• electronics covers, organizers, holders, and jigs
• home and office parts
• aesthetic models where a neutral, technical-looking color is needed

Printing properties of PETG Prusament

Prusament PETG is designed for stable, user-friendly printing with a lower risk of deformation compared to materials like ABS or ASA.

Recommended general printing conditions for PETG Prusament:

• Nozzle temperature: approximately 230–250 °C (depending on the printer and profile)
• Bed temperature: approximately 70–90 °C
• Print bed: textured or smooth PEI sheet with appropriate surface preparation (cleanliness, or a thin layer of release agent according to the manufacturer's recommendations)
• Print speed: medium (e.g., 40–80 mm/s depending on model complexity)

PETG generally offers:

• higher temperature resistance than PLA
• better toughness and less brittleness
• good chemical resistance for common use

NFC compatibility and OpenPrintTag

This product is marked as "NFC Compatible", which means that:

• the refill can be used with the new type of Prusament NFC spools, which contain an OpenPrintTag NFC chip,
• the NFC tag stores information about the material (filament type, color, recommended parameters...) directly in the chip – the printer or application can read them in the future and automatically use the correct settings,
• the OpenPrintTag standard is open and offline, without dependence on a specific cloud or subscription.

Thanks to this, this refill is an excellent choice for users who want to be ready for the new generation of smart spools and automated printing profiles.

Ecology and sustainability

Using refills on original Prusament spools brings:

• significant reduction in plastic waste – you use the spool sides repeatedly,
• smaller volume of waste thanks to the cardboard core,
• more efficient logistics and storage.

If you want to move your 3D printing towards more sustainable operation, Prusament refill systems are one of the easiest ways.
