SUNLU PLA Classic Cherry Red 1.75 mm 1 kg 3D Printer Filament

PLA Classic filament in Cherry Red delivers consistent, bubble-free printing with a smooth surface finish. Its precise 1.75 mm diameter and tight ±0.02 mm tolerance ensure reliable feeding and excellent dimensional accuracy on a wide range of FDM printers.

Advantages

Made from premium polylactic acid, this filament offers low warping and a nearly odourless printing experience. The tangle-free and bubble-free design reduces nozzle clogs and ensures strong layer adhesion. With a tensile strength of 60 MPa and 20% elongation at break, printed parts are robust yet slightly ductile. The controlled melt flow index of 8-12 g/10min provides stable extrusion for detailed models.

Suitable for

• Hobbyists and makers
