Spectrum PET-G 1.75 mm 1 kg filament — Olive Green (3D printer material)

Spectrum PET-G 1.75 mm 1 kg filament in Olive Green is a thermoplastic extrusion material designed for FDM/FFF 3D printers. The PET-G formulation offers a balance of toughness, good layer adhesion and improved chemical resistance compared with common materials, while exhibiting reduced warping versus many engineering-grade filaments. The 1.75 mm diameter filament comes wound on a 1,000 g spool and is compatible with printers and extruders specified for 1.75 mm feed. Typical extrusion temperatures range between 230 °C and 260 °C, making the spool suitable for printing functional parts, prototypes and visual models that require a combination of dimensional stability and moderate impact resistance.

Advantages

Spectrum PET-G delivers reliable interlayer bonding and lower shrinkage than many alternatives, which reduces the likelihood of warping on small and medium prints. The olive green color provides consistent pigmentation across the spool for uniform surface appearance. PET-G’s chemical resistance and toughness make it an appropriate choice when parts may be exposed to moisture or light chemicals. The product is supplied as a 1 kg sealed spool for convenient storage and continuous printing.

Suitable for

• Functional prototypes and end-use parts with moderate mechanical stress
• Visual models, colored fixtures and display elements
• Hobbyist projects and small-batch manufacturing
• Parts requiring improved chemical resistance compared with PLA

How to use

Load the 1.75 mm filament into a compatible FDM/FFF printer according to the printer manufacturer’s instructions. Set the nozzle temperature within the recommended range of 230–260 °C and adjust bed temperature as needed for adhesion; a heated bed is advisable to minimize first-layer issues. Calibrate extrusion multiplier and retraction settings to suit the specific hotend and extruder: PET-G typically requires lower retraction distance and moderate retraction speed compared with PLA to prevent stringing. Print at moderate speeds and allow adequate cooling for overhangs and bridges, adjusting fan settings based on part geometry.

Usage recommendations

Store the filament in a dry environment or sealed with desiccant to preserve print quality. When switching from other materials, purge the hotend to avoid contamination. Test a small calibration print to fine-tune temperature, flow and retraction for optimal surface finish and dimensional accuracy.
