Durable PETG filament for functional 3D prints

SUNLU PETG White combines easy processing with mechanical durability, good layer adhesion, and a clean white color. It is suitable for printing solid components, holders, covers, organizers, prototypes, and practical products for the home or workshop.

Thanks to its precise diameter and tolerance of ± 0.02 mm, the filament passes evenly through the extruder and helps achieve a stable material flow. PETG creates tough models with a limited risk of warping and good impact resistance.

Why choose SUNLU PETG White?

• Strong bonding between individual layers for durable functional parts
• High toughness and impact resistance
• Dimensional tolerance of ± 0.02 mm for stable extrusion
• Clean white color suitable for technical and design models
• Printing at speeds of up to 300 mm/s with appropriate printer settings
• Compatible with common FDM/FFF 3D printers
• 1 kg of material, approximately 320 meters of filament

Recommended print settings

Optimal settings may vary depending on the printer design, hotend type, speed, cooling, and model size. For the best first-layer adhesion, we recommend a clean print bed and a correctly set nozzle distance.

Filament storage

PETG may start producing more strings or exhibit reduced surface quality when exposed to air humidity for an extended period. Store the filament in a sealed package with desiccant, ideally at a relative humidity below 20%. If cracking, bubbles, or excessive stringing appear during printing, drying the material before use is recommended.
