???Strong PETG Filament???PETG is a thermoplastic material that is essentially odorless when printed, has printability close to PLA+, has outstanding toughness and high impact strength, is weather resistant, and is your filament of choice for printing tough items and providing a glossy finish. ???High Accuracy & Consistency???Advanced CCD diameter measurement and adaptive control system in manufacturing ensure that these PETG filaments have a diameter of 1.75 mm with a dimensional accuracy of +/-0.02 mm and a net weight of 1 kg spool (2.2 lbs). ???Neatly arranged & Easy to Use??? Full mechanical winding and strict manual examination, which guarantee the PETG filaments tidy and easy to be fed; Larger spool inner diameter design makes feeding smoother. ???No Clogging & No Bubble???The raw materials are dried before manufacturing, no clogging, super strong interlayer bonding and great fluidity, making the extrusion process smooth and stable. Completely dried for 24 hours before packing and vacuum sealed with desiccant inside the bag to protect the filament from moisture and no clogging and bubbling problems.
