Prusament PETG Prusa Galaxy Black 900g Refill (NFC Compatible)

Prusament PETG Prusa Galaxy Black 900g Refill (NFC Compatible)

Prusament PETG Prusa Galaxy Black is a top-tier PETG filament from Prusa Polymers in a practical refill pack (without plastic spool), designed for the reusable Prusament spool with an integrated NFC chip. The popular Prusa Galaxy Black color combines a deep black base with fine glitters that hide minor surface imperfections and give every print a premium look.

The Refill concept allows for a significant reduction in plastic waste, lower storage and transport requirements, while maintaining all the benefits of original Prusament – precisely controlled production, tight diameter tolerances, and perfect winding.

Key Features

• Premium PETG filament Prusament – produced in-house by Prusa Research in the Czech Republic
• Prusa Galaxy Black color – deep black with fine shimmer, perfectly masks layers and minor imperfections
• Refill 900 g without spool – intended for the reusable Prusament spool with NFC, eco-friendly packaging
• NFC compatible – the spool with an NFC chip, after mounting the refill coil, allows automatic loading of the material type on supported Prusa printers
• PETG material – higher toughness, impact, and temperature resistance than PLA, less brittle
• High dimensional accuracy – diameter 1.75 mm with tight tolerances, very consistent diameter and color
• Excellent winding – minimizes the risk of tangling, suitable for longer print jobs
• Versatile use – functional parts, covers, brackets, technical models, and design decorations
• Made in EU (Czech Republic) – controlled quality from granules to finished filament

Recommended Use

Prusament PETG Prusa Galaxy Black Refill is the ideal choice for users who:

• are looking for a universal technical filament with better durability than PLA,
• prefer a shimmering black surface that looks premium and hides layers well,
• want to reduce plastic waste by using refill systems,
• use Original Prusa printers with NFC support and want the benefits of automatic profiles.

Typical applications:

• functional parts and brackets for home, workshop, and office,
• electronics and mechanical parts covers,
• decorative and technical models that need to look good and last,
• parts exposed to higher temperatures than standard PLA can handle (e.g., in a car or near heat sources, within reasonable PETG limits).

Print Settings (typical values)

Specific recommended profiles can be found in PrusaSlicer for Prusament PETG material.

• Nozzle temperature: approx. 230–250 °C (depending on printer and speed)
• Bed temperature: approx. 70–90 °C
• Print speed: commonly 40–60 mm/s (can be adjusted according to profile and model geometry)
• Fan: rather lower intensity compared to PLA (e.g., 10–40 %), for better layering and adhesion

For best adhesion, we recommend a clean print surface (IPA) and for larger parts, possibly a brim or "mouse ears" at the corners of the model.

Advantages of PETG over PLA

• Higher toughness and impact resistance – parts handle mechanical stress better
• Better temperature resistance – more suitable for applications where the part might heat up
• Lower brittleness – lower risk of cracking during assembly or use
• Good chemical resistance to common household chemicals (within PETG limits)

At the same time, PETG remains relatively easy to print (compared to e.g., PC or ABS) and less prone to warping than many other technical materials.

Eco-friendly Refill System

The refill pack is designed as a refill for an existing Prusament spool:

1. After consuming the original Prusament, remove the spool sides.
2. Place them onto the new Prusament PETG Prusa Galaxy Black 900g Refill.
3. You get a full-fledged spool with an NFC chip without needing to throw away the plastic sides.

This system reduces the volume of plastic waste, saves storage space, and is more environmentally friendly.
