Manufactured to very tight tolerances and from the highest-quality materials, PLA 3D Printing Filament does not require a heated print bed and is less prone to warping than other filament materials. Designed for compatibility with most commercially available printers, it can be cut, filed or glued post printing, but polylactic acid filament should not be used with acetone. With diameter tolerances of 0.05mm or less, filament ensures consistent feeding and stable prints every time. Custom spool is designed for strength and balance for uniform feeding. It is packaged in a vacuum-sealed bag, including desiccant, to promote longevity and prevent the introduction of moisture. More from the Manufacturer.
