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

Product Description

Prusament PLA Prusa Galaxy Black 900g Refill (NFC Compatible) is a premium PLA filament from Prusa Research in an eco-friendly refill variant. The filament is wound on a paper core, which you simply fit with plastic sides from an empty original Prusament spool – thus obtaining a full-fledged smart spool with NFC while reducing the amount of plastic waste.

The Prusa Galaxy Black shade is characterized by a deep black color with fine glitter, which perfectly masks layers and minor print imperfections. The surface of the prints looks luxurious and is very popular for design elements, functional interior parts, figures, and presentation models.

Main Advantages

• Eco-friendly refill system – reuse of plastic sides of the original Prusament spool
• Integrated NFC tag (OpenPrintTag) – compatible with the standard for smart filament identification
• Premium PLA produced in‑house by Prusa Polymers – consistent composition and quality control
• Dense glitter pigmentation "Galaxy Black" – great at hiding layers and imperfections
• High dimensional accuracy – diameter tolerance ±0.02 mm
• Easy printing – low warping, excellent layer adhesion, and detailed surface
• Universal use – prototypes, functional parts, design models, decorations, cosplay, and figures

NFC Compatibility – OpenPrintTag

This refill is NFC compatible. After mounting on an original Prusament spool with an NFC tag, you can use:

• storage of material information (type, color, density, recommended temperatures)
• easier filament identification using compatible NFC readers and applications
• the OpenPrintTag open standard, which allows expansion and integration into your own workflows

Recommended Use

Prusament PLA Prusa Galaxy Black is suitable mainly for:

• representative prints – showroom, presentation models, gifts
• aesthetic functional parts – holders, covers, organizers, home and office accessories
• figures and gaming accessories – miniatures, board game parts, models
• cosplay and decorations – costume parts, props, decorative elements

Thanks to its very good printability, it is suitable for both beginners and advanced users who require a professional look for their prints.

Printing Recommendations

Recommended Print Settings (PLA)

• Nozzle temperature: approx. 205–225 °C (follow the Prusament PLA profile for the specific printer)
• Bed temperature: approx. 50–60 °C
• Print speed: usually 40–60 mm/s (depending on model complexity)
• Fan: 100% after the first layers for sharp details and bridges

Before printing, always:

• thoroughly clean the print surface (lukewarm water + detergent, then IPA according to the printer manufacturer's recommendation)
• check the first layer and the correct distance of the nozzle from the bed

For consistent results, it is advisable to store the filament in a dry place; for well-dried PLA, slightly higher printing temperatures may be required.

Material Properties

PLA (polylactic acid polymers) is a hard, rigid, and dimensionally stable material with minimal warping. It is excellent for precise parts, prototypes, and decorative objects.

PLA Advantages:

• easy to print and set up
• low or no warping
• very good detail rendering
• suitable for most non-functional or lightly loaded parts

PLA Disadvantages:

• lower temperature resistance – unsuitable for parts exposed to high temperatures (e.g., in a car in the sun)
• brittler character – less suitable for parts stressed by impacts or bending

Compatibility

The filament is designed for all common FDM/FFF 3D printers using PLA:

• fully compatible with Original Prusa printers (e.g., MINI, MK3, MK4, XL)
• usable on printers of other brands with a nozzle for PLA and a spool holder for 1.75 mm diameter

The refill concept requires an original Prusament spool – the plastic sides from the original spool snap onto the cardboard core of the refill.

Packaging

• tightly wound filament on a cardboard core – refill
• protective packaging for safe transport and protection against moisture

This product is an ideal choice for users who want top print quality, the luxurious look of Galaxy Black, and at the same time prefer a sustainable refill solution with NFC compatibility.
