Precisely wound filament on a ventilated spool ensures smooth unwinding and reliable extrusion without knots or snags—ideal for long prints.
The perforated spool with a large central hole makes it easy to mount on the printer holder, improves airflow, and reduces packaging weight.
Even layering of material on the spool supports regular filament feeding and stable surface quality throughout the print.
Sunlu PLA Classic is an improved PLA designed for reliable and clean printing. The optimal speed range of 60–150 mm/s ensures a great balance between detail and performance, while the ability to print up to 600 mm/s is ideal for rapid prototyping. The matte Sunny Orange surface highlights model lines and hides minor imperfections.
Thanks to the precise 1.75 mm ±0.02 mm tolerance and careful winding, feeding is smooth and stable, minimizing the risk of clogging. The material is easy to process—supports are easy to remove, and finished parts achieve higher toughness (approx. 18 kJ/m²), making them better suited for everyday use.
