Prusament PETG Galaxy Black 2 kg (NFC)

Product description

Prusament PETG Galaxy Black 2 kg (NFC) is a top-of-the-line filament from Prusa Polymers, based on high-quality PETG material. It combines the mechanical resistance and thermal stability of PETG with the attractive appearance of the popular Galaxy Black color – a deep black complemented by fine shimmering particles that give the prints a premium look.

The large 2 kg spool is suitable for long print runs, large parts, or serial production of prototypes. The integrated NFC tag (OpenPrintTag) allows compatible printers and applications to automatically read material information, simplifying print preparation and filament stock tracking.

Main advantages

• Premium PETG filament manufactured and measured in strictly controlled Prusament production
• Galaxy Black color – deep black with fine shimmer, suitable for technical and design parts
• Large 2 kg spool – ideal for long prints without the need for filament changes
• Integrated NFC chip (OpenPrintTag) – fast loading of material parameters by compatible printers and applications
• High strength and toughness – suitable for mechanically stressed functional parts
• Good thermal and chemical resistance compared to PLA
• Low shrinkage and minimal warping – reliable printing even for larger objects
• Excellent layer adhesion, waterproof prints suitable for indoor and outdoor use

Recommended use

Prusament PETG Galaxy Black is suitable for:

• Functional prototypes and mechanical components
• Electronics covers, holders, and fixtures
• Parts for indoor and outdoor use
• Design models, decorations, and technical models where an elegant black surface with shimmer is required
• Long print jobs and small series, where the 2 kg spool minimizes the need for material changes

Print settings (indicative)

Specific recommended values for Prusament PETG may vary slightly depending on the printer, but generally, these ranges are used:

• Nozzle temperature: approx. 230–250 °C
• Bed temperature: approx. 70–90 °C
• Recommended print surface: textured / satin PEI sheet or other surface suitable for PETG
• Cooling: medium (lower than for PLA) for better layer adhesion

For Original Prusa printer users, ready-made Prusament PETG profiles are available, so you just need to select the material in PrusaSlicer and print.

Tips for successful printing

• PETG tends to string slightly – correct retraction and temperature settings will help
• The material is more sensitive to moisture – storage in a dry place or occasional drying is recommended
• On smooth PEI sheets, PETG can stick very strongly – use a suitable release layer (e.g., glue stick) and follow the printer manufacturer's recommendations

Technical parameters
