Prusament PETG Urban Grey 1kg (NFC)

Prusament PETG Urban Grey is a premium PETG filament manufactured directly by Prusa Research. Each spool is produced and measured with high precision to ensure constant diameter tolerance and color consistency. The Urban Grey shade is a versatile neutral gray, suitable for technical parts, design models, and prototypes where you don't want an overly striking color.

The built-in NFC chip (OpenPrintTag / Prusament NFC) allows compatible printers and apps to read filament information directly from the spool. This simplifies material identification, inventory management, and print settings.

Main advantages of Prusament PETG Urban Grey

• Premium PETG from Prusa Research – the same type of material Prusa uses for printing parts for its printers
• Integrated NFC chip – quick identification of spool, material, and color, simpler filament management
• High toughness and durability – suitable for functional components and mechanically stressed parts
• Good thermal resistance – usable for parts in interiors and exteriors (e.g., holders, covers, jigs)
• Low warping – easy printing even of larger models
• Consistent Urban Grey color – technical, neutral, and elegant look of prints
• Diameter accuracy ±0.02–0.03 mm (depending on production batch) – consistent extrusion and reliable printing
• Thorough quality control of each spool – possibility to verify parameters of a specific spool on the Prusament portal

Recommended Use

Prusament PETG Urban Grey is particularly suitable for:

• functional and mechanical parts
• jigs, holders, grips, and assembly aids
• covers for electronics and technical devices
• prototypes for shape and function verification
• parts exposed to higher temperatures than PLA can withstand
• models for interior and exterior

Thanks to the neutral gray color, it is ideal where you do not want overly prominent colored parts, or you need a professional, technical look.

Printing recommendations (approximate)

Specific recommendations may vary slightly depending on the printer, nozzle, and environment, but typically:

• Nozzle temperature: approx. 230–250 °C
• Bed temperature: approx. 70–90 °C
• Recommended bed surface: textured or satin sheet with appropriate surface preparation
• Print speed: medium (e.g., 40–60 mm/s) for quality surface and strength

For maximum adhesion of the first layer, it is important to thoroughly degrease the bed (e.g., with isopropyl alcohol) and set the first layer height correctly.

Tips for successful PETG printing

• Do not leave the nozzle stationary in one place unnecessarily – PETG tends to "burn" and form strings.
• Use slightly higher retractions than for PLA, but avoid extreme values to prevent material from jamming in the nozzle.
• When printing on a smooth PEI sheet, follow the manufacturer's recommended procedures (often a thin layer of glue is recommended as a release layer to prevent over-adhesion of the print).
• Store the spool in a dry place – PETG is slightly hygroscopic; long-term exposure to moisture can degrade print quality.

Technical parameters

*Specific values may vary slightly depending on the production batch and printer type.

Who is this filament suitable for

• Beginners who already handle PLA and want to move to a more durable material
