Prusament PETG Carmine Red 1kg (NFC)

Product description

Prusament PETG Carmine Red 1kg (NFC) is a top‑class filament made from PETG material, manufactured in‑house by Prusa Research. Each spool is continuously measured and inspected during production, which guarantees a highly accurate diameter of ±0,02 mm and perfectly consistent color along the entire length of the winding.

The shade Carmine Red Transparent is a rich carmine red with a transparent effect – prints look bold and “vivid” and beautifully shine through when backlit. This makes it an excellent choice for designer parts, covers, backlit panels, decorations, but also for functional and technical components where you will appreciate higher heat resistance and toughness compared to PLA.

The integrated NFC tag (OpenPrintTag standard) allows you to wirelessly store and read information about the filament – for example material type, color, recommended temperatures, or remaining amount. Your printer or mobile application can thus automatically recognize the spool, without dependence on the cloud or proprietary services.

PETG material properties

PETG is a universal material for functional prototypes and final parts:

• Higher heat resistance than PLA (approx. up to 70 °C)
• High toughness and impact resistance – suitable for mechanically stressed parts
• Low warping and shrinkage – suitable even for larger prints without an enclosed chamber
• Very good layer adhesion – suitable even for nearly watertight parts
• Almost no odor during printing
• Glossy and smooth surface of the print

Unlike PLA, PETG is slightly softer and more flexible, less brittle, and handles long‑term loads and use in more demanding environments better (workshop, garage, car interior, etc.).

Typical applications

• Functional mechanical components – holders, mounts, covers, jigs, clamps, fixtures
• Parts for Original Prusa and other 3D printers – PETG has long been used for plastic parts of Prusa printers
• Designer and backlit models – logos, advertising elements, lamps, light fixtures, cosplay accessories
• Covers and enclosures – electronics, sensors, boxes used indoors and in the workshop
• Water‑resistant containers and elements – thanks to the excellent layer adhesion (with proper print settings)

Advantages and disadvantages

Advantages:

• Premium filament manufactured directly by Prusa Research
• Integrated NFC (OpenPrintTag) – easy identification of the spool and parameters
• High dimensional accuracy ±0,02 mm
• Excellent mechanical resistance and toughness
• Higher heat resistance compared to PLA
• Low warping – suitable even for larger models
• Transparent carmine red color for eye‑catching and backlit prints

Disadvantages (typical for PETG):

• Tendency to stringing – requires tuning of retraction and temperature
• Worse bridging than PLA
• Very strong adhesion to the build plate – care is needed when removing models
• Worse detail than PLA, especially on very small objects

Recommended print settings

Values may vary depending on the printer; we recommend using the preset Prusament PETG profiles in PrusaSlicer.

• Nozzle temperature: approximately 240–260 °C (typically 250 °C)
• Bed temperature: approx. 70–90 °C (typically 80 °C)
• Recommended print surface: textured or satin PEI sheet; glass with a suitable adhesion layer is also possible
• Cooling: fan on, medium power (approx. 40–60 %)
• Print speed: medium to high, depending on the printer capabilities

To reduce stringing with PETG, the following helps:

• slight reduction of nozzle temperature,
• increased retraction,
• well‑dried filament.

Tips for use and maintenance

• Before printing, check that the print surface is clean (free of grease and residues of glue or fingerprints).
• For large models, it is advisable to slightly raise the first layer height or use a separating layer (e.g. glue stick) to make removal easier and avoid damaging the surface.
• For long‑term storage, keep the spool in a sealed bag with desiccant – PETG can absorb moisture.
• To read and manage the NFC tag, you can use compatible mobile applications or printers supporting OpenPrintTag.

Who is this filament suitable for?

• Advanced and beginner users who want to move from PLA to a more durable material
• Home workshops, small businesses, prototyping labs
• Creators of designer, decorative, and backlit objects
• Users of Original Prusa printers who want to take advantage of preset profiles and top‑class reliability
