NEBULA PETG Gray – Gray filament for durable and precise prints

Nebula PETG Gray is a universal material for everyday 3D printing of technical and design parts. It combines high strength, toughness and good temperature and chemical resistance, while printing easily and with a low risk of warping.

Why choose Nebula PETG

• Durable functional parts – excellent layer adhesion and increased temperature resistance.
• Chemical resistance – to oils, salts, weak acids and bases.
• Stable dimensions – diameter accuracy of ±0.05 mm for consistent results.
• Smooth, slightly glossy surface – elegant Gray color suppresses small imperfections.
• Ready to print – vacuum packed with silica gel, clean spool for smooth unwinding.

Recommended print settings

• Nozzle: 220–240 °C
• Bed: 60–90 °C
• Speed: approx. 35–60 mm/s
• Cooling: 0–25 % (depending on geometry)
• Chamber: not required

Tip: For best adhesion use a PEI surface, textured PEI, or glue/spray on smooth glass. Do not print PETG too close to the PEI to avoid surface damage.

Compatibility and spool

• The manufacturer states compatibility with Bambu AMS. Two spool versions may be in circulation: older ~80 mm width and new ~67 mm (AMS-friendly). Spool dimensions: Ø 200 mm, hole 52 mm.

Packaging

• Vacuum sealed with silica gel in a cardboard box – the material is protected against moisture and ready for immediate use.

Applications

• Prototypes, covers and holders, fixtures, thin-walled prints, interior parts, decorative and functional components.

Note

• The material may be suitable for food contact after meeting requirements (certification of the finished part is necessary). Store in a dry place; if it becomes moist, dry at around 65–70 °C for 4–6 h.
