Sunlu PETG 1.75mm 3 KG
SUNLU PETG Filament – Large Spool, High Strength and Durability
Big Roll PETG Filament
SUNLU PETG is now available on large 3 kg spools, which reduces the need for frequent changes and increases productivity, while also being cost-effective.

Excellent Printing Experience
SUNLU PETG combines the advantages of both PLA and ABS, making 3D printing more convenient, easy, and reliable.

Strong Layer-to-Layer Adhesion
PETG filament ensures excellent layer adhesion, reducing the risk of warping and providing smooth, strong prints with high structural integrity.


High Impact Strength and Robustness
With its toughness and high impact resistance, PETG prints can withstand shocks, drops, and stress without breaking. It is perfect for durable parts that must endure both daily use and heavy loads.
Long-Term Durability
PETG prints retain their properties over time and are suitable for both indoor and outdoor use where weather resistance is required.
Seamless Printing
SUNLU PETG is optimized to minimize stringing and prevent nozzle clogging, ensuring consistent and smooth printing every time.
