The light pink 2.85mm PLA filament from 123-3D.ie makes 3D printing at low temperatures easy. This PLA filament is stronger and is less brittle compared to standard PLA. In addition, it has all the advantages of PLA: it is biodegradable, does not warp, does not deform and leaves little odour during 3D printing. A heated bed is not necessary.
