Environmentally friendly PLA+: PLA+ is an improved version of ordinary PLA. It has a higher strength and better toughness and is not easy to break. Made from starch materials from renewable plant resources, environmentally friendly and non-toxic, ideal for indoor printing. Dimensions tolerance +/- 0.03 mm: eSUN PLA+ 3D printer filaments are manufactured with more accurate specifications. Minimum tolerance and low distortion to ensure even feed and stable prints, no bubbles, less threading, extremely high success rate. 【Tangle-free and no clogging】Total length: 340-350m. Full 1 kg 3D printer filament roll, perfect roundness and very tight diameter tolerance, good winding, does not overlap or tangle. Melt well, feed evenly and consistently without clogging the nozzle or extruder. Good printability: PLA+ retains all the benefits of PLA, easy to print like ordinary PLA, low shrinkage, no deformation, no cracks, high pressure precision. Widely used in machines, electronic equipment, cars, decorations, cosplay and other items. 【High Compatibility】Compatible with most FDM 3D printers, such as: Prusa, MakerBot, UltiMaker, MK3, Ender 3, Simplify3D, Flashforge, etc. Good layer binding performance meets your requirements for printing functional parts with higher toughness.
