1 Kg (2.2 lbs) spool of 1.75mm PLA filament.PLA, aka Polylactic Acid, is a multipurpose material commonly used in 3D printing. PLA is a bioplastic, which means it is made from renewable natural resources such as corn starch and tapioca products. As a biodegradable material it is much better for the environment, especially compared to petrochemical-based alternatives (such as ABS).We tend to favor PLA as our default printing material due to its high strength and minimal warping.Recommended Extrusion Temperatures: 185C-205CDimensional Accuracy: ±0.07mmSpool Dimensions (Aprox.): 200mm Total Diameter x 50mm Inner Hole Diameter x 65mm HeightAll filament comes sealed in a bag with desiccant.
