Prusament PETG Carmine Red Transparent 1kg (NFC)

Product Description

Prusament PETG Carmine Red 1kg (NFC) is a top-of-the-line filament made of PETG material, manufactured internally by Prusa Research. Each spool is continuously measured and inspected during production, which guarantees very precise diameter ±0.02 mm and perfectly consistent color throughout the entire length of the winding.

The shade Carmine Red Transparent is a deep carmine red with a transparent effect – prints look striking, "vibrant," and glow beautifully when backlit. This makes it a great choice for design parts, covers, backlit panels, decorations, but also for functional and technical components where you appreciate higher thermal resistance and toughness compared to PLA.

The integrated NFC tag (OpenPrintTag standard) allows for wireless storage and reading of filament information – for example, material type, color, recommended temperatures, or remaining quantity. 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 versatile material for functional prototypes and final products:

• Higher thermal resistance than PLA (up to approx. 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 bonding – suitable even for nearly waterproof 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 conditions (workshop, garage, car interior, etc.) better.

Typical Use

• Functional mechanical components – holders, grips, covers, fixtures, clamps, mounting elements
• Parts for Original Prusa and other 3D printers – PETG has long been used for the plastic parts of Prusa printers
• Design and backlit models – logos, advertising elements, lamps, light fixtures, cosplay accessories
• Covers and cases – electronics, sensors, boxes used in interiors and workshops
• Water-resistant containers and elements – thanks to excellent layer bonding (with correct print settings)

Pros and Cons

Pros:

• 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 thermal resistance compared to PLA
• Low warping – suitable even for larger models
• Transparent carmine red color for impressive and backlit prints

Cons (typical for PETG):

• Tendency for stringing – retraction and temperature need to be fine-tuned
• Poorer bridging than with PLA
• Very strong adhesion to the heatbed – caution is needed when removing models
• Poorer details than PLA, especially for very small objects

Recommended Print Settings

Values may vary by printer, we recommend using pre-set Prusament PETG profiles in PrusaSlicer.

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

To limit stringing with PETG, it helps to:

• slightly lower the nozzle temperature,
• increase retraction,
• use well-dried filament.

Tips for Use and Maintenance

• Before printing, check that the print bed is clean (free of grease, adhesive residues, or fingerprints).
• For large models, it is advisable to lower the first layer or use a separation layer (e.g., glue stick) to facilitate print removal and avoid damaging the surface.
• For long-term storage, keep the spool in a sealed bag with desiccant – PETG can absorb moisture.
• For reading and managing the NFC tag, compatible mobile applications or printers supporting OpenPrintTag can be used.

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 design, decorative and backlit objects
• Users of Original Prusa printers who want to utilize pre-set profiles and top-tier reliability
