Anycubic Pla 3D Printer Filament, Grey, 1Kg Spool, 2.2 Lbs, Dimensional Accuracy Product Details ????????? ???????????? Anycubic 3D Printer PLA filament of 1.75mm diameter, Minimum dimensional tolerance 0.02mm, which making filament outflow smoother, came out homogeneous. The low shrinkage, stable printing dimensions make the fusion between the layers was very good to obtain an even better bridging result. You don't worry the diameter changes a lot then the feed rate is disrupted with thicker and thinner layers at all ????? ????? ??????? ???????? The 3D Printing PLA filament was neat on the roll and leaves the spool easily without any crossed turns. Resulting in less thread pulling and twisting, no clogging, super under-extruding. It produces the cleanest, least stringing prints of any of the filaments you have used whilst resisting warping and also providing the glossiest finish. Without a single jam and adhesion issue which meeting your demands for printing freely ?????-???? ??????-????? Designed and Manufactured with Clog-Free patent to guarantee a smooth and stable printing experience with our PLA refills. Completely dried for 24 hours before packaging and vacuum sealed with desiccants in nylon re-bag, enable much smoother and more stable printing. Larger spool inner diameter design makes feeding smoother ????? ?????????????? Made from starch raw materials derived from renewable plant resources, PLA filament boasts lower melting temperature, even does not need a heated bed. No odor, no pollution and non-toxic during the printing. Anycubic PLA Filament Compatible perfectly with most FDM 3D Printers and 3D Pens that use 1.75MM filament on the market, such as Prusa, Makerbot, MK3, Ender 3, CR 10, Kobra, Mega, Chiron, Monoprice FlashForge and more ????????? ????????????? 1. Install the spool on the spool holder of a 3D printer, and preheat the nozzle of the 3D printer. 2. Cut the filament tip diagonally, and guide it through the extruder and feeding tube. 3. Manually push the filament through the feeding tube to the nozzle, until the filament melt through the nozzle. Note: When installing and changing filament, we highly suggest to preheat the nozzle firstly to reduce the nozzle block risk Payment We accept PayPal and credit cards via PayPal.
