About this item ?????? ??????? ??? ????????:It has the advantages of no clogging, no bubbles, no tangles, no warpage, no drawing, easy to use, and the threads are neatly arranged, which effectively reduces the risk of knotting. ??????????????? ????????: ANYCUBIC PLA filament is made of starch raw materials extracted from renewable plant resources (such as corn, cassava, etc.), which is a new type of environmentally material ?.???? ????????: dimensional accuracy +/- 0.02mm to ensure even and smooth wire output. Anycubic filament has wide compatibility due to its small diameter error, and is suitable for almost all 1.75mm FDM 3D printers ??????? ?????????: When installing and replacing consumables, it is necessary to heat the print head (heated above 200°C), otherwise the 3D printer will be easily damaged. Recommended printing temperature is 190-230℃ nozzle/extrusion temperature ?????? ?????????: completely dry for 24 hours before packaging, and vacuum seal with desiccant in a re-sealable nylon bag. Compared with ABS filament, PLA is less likely to deform (this makes printing easier)
