SUNLU 3D Printer Filament – Dimensional Accuracy

SUNLU filament has a dimensional accuracy of ±0.02mm. The small diameter error provides broad compatibility and ensures stable and reliable printing. Low shrinkage and consistent diameter (±0.02mm) guarantee smooth filament feeding and consistent results. The filament works perfectly with most FDM 3D printers, including Bambu Lab, Creality, Prusa, Anycubic, etc.

Secure Vacuum Sealing
All SUNLU filaments come vacuum-sealed with a desiccant bag, protecting against dust and moisture during transport. This ensures optimal filament quality and high print consistency.

Quality Assurance in Every Spool
SUNLU 1.75mm filament maintains a strict diameter precision of ±0.02mm. This ensures smooth, tangle-free printing and minimizes the risk of nozzle clogging – for a better and more efficient printing experience.

Eco-friendly and User-friendly
Made from high-quality PLA, SUNLU filament is biodegradable and environmentally friendly. It requires a lower melting temperature, eliminating the need for a heated print bed – and it emits no unpleasant odor, making it ideal for both home and workplace.
