Boosting Efficiency with Intelligent ldentificationAnycubic filaments feature intelligent identification chips that integrate seamlessly with the ACE Pro, allowing for automatic identification of printing information and enhancing the printing experience. Accuracy & Consistency Anycubic 3D Printer PLA filament of 1.75mm diameter, minimum dimensional tolerance +/- 0.02mm, which makes filament outflow smoother, came out homogeneous. The low shrinkage and stable printing dimensions make the fusion between the layers 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. Neat Spool & Premium Quality The 3D Printing PLA filament was neat on the roll and easily left the spool without crossing turns. Resulting in less thread pulling and twisting, no clogging, and super under-extruding. It produces the cleanest, least stringing prints of any of the filaments you have
