Prusament PETG Matte Black 1kg (NFC)

Product Description

Prusament PETG Matte Black 1kg (NFC) is a top-of-the-line PETG filament with an elegant matte black surface, manufactured in-house by Prusa Research. The entire manufacturing process is carefully monitored, resulting in exceptional dimensional accuracy of ±0.02 mm and consistent color throughout the spool's length. This ensures reliable and repeatable printing even for detailed or larger technical parts. The matte surface reduces the visibility of layers and fingerprints and is suitable for functional and design prototypes, electronics enclosures, brackets, jigs, mechanical parts, and components for both indoor and outdoor use. The built-in NFC/OpenPrintTag label stores important material information directly on the spool. For compatible printers and applications, it enables quick filament identification and easier inventory management.

Main Features

• Material: PETG (Glycol-modified Polyethylene Terephthalate)
• Color: Matte Black
• Filament Weight: 1 kg of pure material
• Filament Diameter: 1.75 mm
• Diameter Tolerance: ±0.02 mm
• Surface: matte, less glossy than classic PETG, hides minor imperfections
• Manufactured in-house by Prusa Research for maximum quality control
• High strength and toughness – suitable for functional and mechanically stressed parts
• Good temperature resistance – suitable for parts exposed to heat (e.g., in a car, near windows, in a workshop)
• Low warping – suitable even for larger models without an enclosed chamber
• Suitable for indoor and outdoor use
• NFC/OpenPrintTag label – stores spool data (material, parameters, etc.)

Recommended Use

PETG Matte Black is an ideal choice for:

• functional and mechanically stressed parts
• brackets, grips, jigs, and assembly aids
• electronics and technical equipment enclosures
• prototypes and final parts for the workshop, office, and home
• parts exposed to higher temperatures than PLA can withstand
• models where a discreet matte surface and good layer masking are desired

Printing Settings (Approximate)

For the best results, we recommend using pre-set Prusament PETG profiles in PrusaSlicer or another slicer and further fine-tuning them according to the printer:

• Nozzle Temperature: approx. 240–260 °C (usually around 250 °C)
• Bed Temperature: approx. 70–90 °C
• Print Surface: textured or satin PEI sheet, or glass with a suitable adhesive layer
• Cooling: medium (e.g., 40–60 %) depending on the model type
• Print Speed: medium, depending on printer capabilities and desired quality

PETG tends to string (ooze threads), so it is advisable to:

• use dry filament (store in sealed boxes, or dry before printing)
• correctly set retraction and nozzle temperature

---

Tips for Printing and Processing

• Always thoroughly degrease the print surface (isopropyl alcohol, etc.) before printing.
• Print the first layer more slowly and with sufficient pressure on the bed for reliable adhesion.
• Be careful when removing the print from the bed – PETG can adhere very strongly to the PEI surface.
• Finished parts can be sanded (ideally gradually with finer grits) and surface-treated with coatings if necessary.
