Prusament PETG Prusa Galaxy Black 1kg (NFC)

Prusament PETG Prusa Galaxy Black is a premium filament from Prusa Research's own production, combining high quality, great printability, and a unique look with metallic glitters in a deep black color. The (NFC) variant is wound on a new smart spool with an OpenPrintTag NFC tag, which allows for easy material identification and more convenient printing workflow.

Main advantages and use

• Easy printing from PETG – very good layer adhesion, low warping, and shrinkage
• Good heat resistance – suitable for functional parts stressed by heat more than PLA
• High strength and durability – ideal for technical components, brackets, covers, and fixtures
• Iconic Galaxy Black look – black with fine glitters hides minor surface imperfections
• Better sandability than PLA – PETG is softer, melts less during sanding
• NFC tag (OpenPrintTag) – the printer or app can read the material type and recommended parameters
• Precise manufacturing – filament diameter controlled with an accuracy of ±0.02 mm for reliable and consistent printing

Typical use:

• functional and technical parts
• electronics covers, holders, assembly fixtures
• design and decorative models with an impressive surface
• prototypes that require strength and partial heat resistance

Printing recommendations

Recommended settings

• Nozzle temperature: approx. 230–250 °C (use the Prusament PETG profile in PrusaSlicer)
• Bed temperature: approx. 70–90 °C
• Printing speed: normal speeds for PETG according to the printer profile
• Cooling: medium, as per the recommendation for the PETG profile

Before printing, ensure that the print surface is clean and degreased according to the recommendations in the 3D Printing Handbook from Prusa Research.

Minimizing stringing

PETG tends to slightly ooze from the nozzle and can create strings (stringing). Recommendations:

• store the filament in a dry place, or dry it before printing according to the manufacturer's recommendations
• use the default Prusament PETG profile in PrusaSlicer (optimized retractions and temperatures)
• any minor "hairs" can be quickly removed with a heat gun by briefly blowing over the model

NFC spool with OpenPrintTag

This version is wound on a newly redesigned spool with an NFC tag:

• OpenPrintTag NFC – rewritable tag with stored material information
• works entirely offline, data is directly on the NFC tag
• compatibility across brands and ecosystems (open standard)
• can be read using the Prusa mobile app and supported printers
• the new spool has a slimmer profile and a locking mechanism for easier recycling and filament drying

Prusament Quality

Prusament PETG is manufactured in-house at Prusa Research with an emphasis on color and dimensional consistency:

• diameter 1.75 mm controlled with ±0.02 mm accuracy
• each batch undergoes detailed quality control
• thanks to precise winding, the filament does not cross and unwinds smoothly even during long prints

Technical parameters

• Material: PETG (polyethylene terephthalate glycol)
• Color: Prusa Galaxy Black (black with glitters)
• Filament diameter: 1.75 mm
• Diameter tolerance: ±0.02 mm
• Net weight of filament: 1 kg
• Spool: new generation with NFC (OpenPrintTag), suitable also for filament drying
• Recommended nozzle temperature: approx. 230–250 °C
• Recommended bed temperature: approx. 70–90 °C
