Prusament PETG Chalky Blue 1 kg (NFC)

Prusament PETG Chalky Blue is a premium PETG filament in an elegant matte pastel blue color, manufactured directly by Prusa Research in the Czech Republic. Each spool is carefully inspected and offers exceptional dimensional accuracy of ±0.02 mm and consistent color throughout the entire length of the filament.

Thanks to the integrated NFC chip, information about the spool (material, color, remaining weight, etc.) can be easily loaded onto compatible Original Prusa 3D printers.

PETG Material Properties

PETG is a versatile technical material suitable for:

• Functional and mechanical parts (brackets, covers, jigs)
• Parts exposed to higher temperatures than PLA
• Larger prints thanks to minimal warping
• Indoor and outdoor use (better resistance than PLA)

Key PETG Properties

• High toughness and impact resistance
• Better heat resistance than PLA
• Low shrinkage and low risk of deformation
• Good interlayer adhesion
• Suitable for both beginners and advanced users

The Chalky Blue color is a soft, matte pastel blue that suppresses layer visibility and gives prints a professional, "chalky" look.

Recommended Use

• Electronics housings, boxes, cable holders
• Mechanical and functional parts in the home and workshop
• Decorations, design objects, cosplay accessories
• Larger models where print stability and minimal warping are important

Print Settings (Guideline)

• Nozzle temperature: approx. 240–250 °C (depending on printer and profile)
• Heatbed temperature: approx. 70–90 °C
• Recommended surface: textured / satin / smooth PEI sheet
• Print speed: usually 40–60 mm/s
• Cooling at a medium level is recommended, not full power like with PLA.

For the best results, we recommend using the official Prusament PETG print profiles in PrusaSlicer (profiles for Original Prusa printers).

NFC Spool

This variant is supplied on an original Prusament spool with an NFC chip (NFC):

• Automatic material identification on compatible printers
• Easy access to parameters of the specific spool
• Overview of material consumption

Advantages of Prusament PETG Chalky Blue (NFC)

• Premium PETG manufactured and controlled in the Czech Republic
• Matte pastel blue "chalky" type color
• Very precise filament diameter (±0.02 mm)
• Stable printing even for larger parts
• Universal use – functional parts, prototypes, design
• Original NFC spool for smart material management

Tips for Successful Printing

• Clean the bed with isopropyl alcohol (IPA) or according to the printer manufacturer's recommendations before printing.
• For larger parts, use a brim or slightly increased bed temperature for better adhesion.
• In case of stringing, lower the nozzle temperature or adjust retractions.
• Store the filament in a dry place; PETG is moderately hygroscopic – for long-term open spools, drying in a filament dryer is suitable.
