Filament PETG Spectrum dark green (RAL 6003) for 3D printing, spool EAN 5903175653291

Spectrum PETG filament in dark green (RAL 6003) is a thermoplastic filament designed for FDM/FFF 3D printing. It offers a balance of strength, slight flexibility and good layer adhesion, making it suitable for durable functional parts as well as decorative objects that require a deep, consistent green tone. The filament is supplied on a ready-to-use spool and is formulated to provide stable extrusion and reduced warping compared with some other materials.

Advantages

The material combines impact resistance and chemical resistance with dimensional stability during printing. Layer bonding is strong, which helps produce mechanically reliable parts. The dark green color provides consistent coverage and good visual opacity for aesthetic parts. PETG typically requires less aggressive bed adhesives than some engineering plastics and shows lower odor during printing.

Suitable for

• Functional prototypes and mechanical components subject to moderate loads
• Outdoor and indoor decorative items where chemical resistance is beneficial
• Parts requiring good layer adhesion and reduced risk of delamination
• Housings, brackets, and fixtures that need a balance of toughness and slight flexibility

When it may not be suitable

PETG is not ideal for applications that require very high temperature resistance (for example continuous exposure above PETG’s glass transition temperature) or for parts that must be fully rigid like some engineering-grade thermosets. Highly detailed micro-features or extremely sharp edges may require fine-tuned print settings to avoid stringing or slight rounding.

Key specifications

• Material: PETG (glycol-modified PET)
• Colour: dark green (approx. RAL 6003)
• Mechanical properties: good impact resistance and moderate flexibility
• Print behaviour: good layer adhesion, low warping tendency
• Chemical resistance: increased resistance compared with standard PLA

How to use

Load the filament onto an FDM/FFF 3D printer configured for PETG. Typical printing temperatures for PETG range higher than PLA; follow your printer and nozzle manufacturer recommendations and adjust extrusion temperature, retraction and print speed to achieve clean results. Use a heated bed and a suitable build surface or adhesive to ensure first-layer adhesion; moderate bed temperatures help minimize warping. Allow printed parts to cool gradually on the bed when possible to preserve dimensional accuracy.

What to consider before purchase

• Ensure your printer is compatible with PETG and can reach recommended extrusion temperatures
• Confirm the colour RAL 6003 (dark green) matches your design or project requirements
• Check spool dimensions and filament diameter compatibility with your extruder and spool holder

Usage recommendations

For best results, print PETG with a slightly slower first layer speed, moderate bed temperature and minimal excessive cooling. Fine-tune retraction to reduce stringing and test print a small part to set optimal temperature and flow settings for your specific printer.
