Prusament PETG Ultramarine Blue 1kg (NFC)

Product description

Prusament PETG Ultramarine Blue 1kg (NFC) is a top-tier PETG filament manufactured directly at Prusa Research on fully controlled production lines. Each spool is precision-wound, with strictly monitored diameter and documented quality – parameters of a specific spool can be looked up by batch on the Prusament portal.

PETG combines the advantages of PLA (easy printing) and ABS (higher toughness and heat resistance). In the Ultramarine Blue shade, you get a rich, deep blue color with a very nice, slightly glossy surface, suitable for both functional parts and representative prototypes and design.

NFC spool – smarter work with filament

This variant is supplied on the new NFC spool with OpenPrintTag technology:

• integrated NFC chip in the spool
• automatic identification of material and its profile on compatible Original Prusa printers (e.g., newer generations with NFC reader)
• facilitates correct profile selection, remaining amount tracking, and material management
• modern, assemblable spool simplifies recycling and potential refills

PETG material properties

PETG is popular for functional and technically stressed prints where there is a need for:

• higher toughness and impact resistance than PLA
• better temperature resistance (commonly around 70–80 °C depending on the part shape)
• good layer adhesion and dimensional stability
• less warping than ABS

Ultramarine Blue PETG is suitable for:

• technical parts and functional prototypes
• electronics covers and holders
• mechanical components with higher loads (clips, mounts, hinges, couplings)
• home and workshop organizers, hooks, storage systems
• design and decorative models where you want an attractive blue surface

Recommended print settings

Specific values may vary by printer and environment, but for Prusament PETG, the following are typically used:

• Nozzle temperature: approx. 240–250 °C
• Heatbed temperature: approx. 80–90 °C
• Recommended surface: textured or satin spring steel sheet (proper surface preparation is necessary for smooth sheets)
• Cooling: medium, according to the PETG profile recommendation (excessive cooling can worsen layer adhesion)

For optimal results, use official profiles for Prusament PETG in PrusaSlicer or other slicers where these profiles are available.

Bed preparation and printing tips

• Thoroughly clean the print sheet before printing (e.g., with isopropyl alcohol on a cooled sheet as recommended by Prusa Research).
• For smooth PEI sheets, it is advisable to use a separation layer (e.g., glue stick) to prevent surface damage from excessive PETG adhesion.
• PETG is more moisture-sensitive than PLA – keep it dry (sealable boxes, silica gel), or dry it before printing if necessary.
• For a clean surface and to minimize "stringing" or nozzle buildup, it is advisable to fine-tune retractions and infill speeds.

Suitable printers

The filament is optimized for:

• Original Prusa MK4, MK3S+, XL, MINI+ and other Original Prusa printers supporting 1.75 mm filament and NFC reader

However, it is fully compatible with most FFF/FDM printers working with 1.75 mm diameter filament, provided correct temperature and PETG profile settings are used.

Key benefits for users

• Premium quality – in-house production by Prusa Research with careful inspection of every spool
• Integrated NFC (OpenPrintTag) – comfortable and modern work with filament on supported printers
• Rich ultramarine blue shade – attractive look for technical and design models
• High toughness and resistance – ideal for functional parts that must endure use
• Excellent diameter accuracy and print stability – fewer problems, clean details, reliable operation
• Universal use – from prototypes through mechanical parts to decorations and models for everyday use
