Prusament PETG Urban Grey 900g Refill (NFC Compatible)

Prusament PETG Urban Grey 900g Refill (NFC Compatible)

Prusament PETG Urban Grey 900g Refill is a top-tier PETG filament from Prusa Polymers in the form of a winding without a plastic spool, designed for use with a reusable Prusament NFC spool. Thanks to the integrated NFC technology in the original spool, it allows for easy material identification and monitoring of the remaining amount directly in the Original Prusa ecosystem.

Main Features

• High-quality PETG from Prusa Polymers – excellent strength-to-flexibility ratio, suitable for functional and aesthetic parts
• Urban Grey color – universal, elegant grey for technical components, covers, fixtures, and design objects
• Refill without spool (900 g) – saves plastic waste, storage space, and shipping costs
• NFC Compatible – designed for rewinding onto an original Prusament NFC spool, which carries a rewritable NFC tag with filament data
• Low stringing and good layer adhesion – easy to achieve strong and dimensionally stable prints
• Made in EU (CZ) – tight diameter tolerance and continuous quality control

Typical Use

Prusament PETG is suitable for:

• Functional technical parts and prototypes
• Covers, holders, fixtures, and assembly aids
• Components with higher heat resistance compared to PLA
• Outdoor or workshop applications where better chemical resistance than PLA is required

Recommended Print Settings

Specific values may vary slightly depending on the printer and environment; typical parameters for Prusament PETG are listed below:

• Nozzle temperature: approx. 240–250 °C
• Bed temperature: approx. 70–90 °C
• Recommended bed surface: textured or satin PEI sheet
• Print speed: medium (e.g., 40–60 mm/s) for best surface quality

For Original Prusa printer users, preset profiles for Prusament PETG are available, which greatly facilitate achieving optimal results.

Advantages of the Refill Solution

• Greener choice – reusing the original Prusament spool with NFC significantly reduces the amount of plastic waste
• Less waste and lower packaging volume – easier storage and transport
• Full compatibility with Prusament NFC spools – the chip in the spool carries material information that can be used in supported software and hardware

Compatibility

• Suitable for FDM/FFF 3D printers with a 1.75 mm filament diameter
• Ideal for Original Prusa printers (MK4, MK3S+, MINI+, XL, and others) with official Prusament PETG profiles
• Can also be used on other compatible 3D printers with the corresponding filament diameter and PETG printing capability

Key Technical Parameters of PETG (general for Prusament PETG)
