PLA (PolyLactic Acid) is a biodegradable plastic, made using cornstarch or sugarcane. It is a renewable raw material which is much more ecologically friendly and safer than ABS plastics. PLA plastics are more flexible as it does not require as high temperatures to manipulate the material; therefore a head bed is not required (compared to ABS). ; What's in the box: 1 x Matte PLA 3D Filament 1.75mm Clay - 1KG ;Features Designed to fit with a wide variety of 3D printers. Smooth and matte looks for aesthetically pleasing printouts High quality materials for consistent thickness to ensure printing accuracy. Less energy needed to print a model Restriction of Hazardous Substance (RoHS) compliant no hazardous substances such as mercury and cadmium are used. Odourless bio-friendly and nontoxic plant-based materials ;Reel diameter 200mm Reel hub diameter 60mm Reel width ; 65mm ; Best printing practices When 3D printing, always work in a well ventilated workspace. Our PLA Filaments are more sensitive to extreme heat when compared to ABS. PLA plastics are harder, but are therefore also relatively brittle when subjected to bending forces. Please store PLA filament away from the sun in a cool dry environment to ensure longevity as moisture can compromise print quality. Optimum Extrusion Temperature 200-230 Celsius Optimum Platform Temperature Glue required if not heated, glue unrequired if 60-80 Celsius Print Speed 40-100mm/s Tolerances 0.02mm ;
