PLA Metal Accurate & Consistent Dimension Strict tolerances ensure consistent dimension of the 1.75 mm PLA filament for smoother and more stable printing, with a dimensional accuracy of +/- 0.02 mm. Less nozzle clogging, higher printing success rate Tangle-free & Neat Spool Full mechanical winding with rigorous manual inspection ensures that the line is neatly arranged on the spools to avoid filament tangles. For more eco-friendly, our PLA comes in cardboard spools, which degrade faster than plastic spools. In addition, there are three holes for monitoring the remaining filament and timely replacement.Coupon Code: IMBF10 Description： Discount Code for ELEGOO all stores: $10 discount on purchases over $150.
