High Toughness PETG 3D Printer Filament has the advantages of high toughness, low shrinkage and superb layer bonding. PETG has the benefits of ABS (stiff, durable strength) and easy to use like PLA, which is an ideal filament material choice for you to print. High AccuracyMinimum tolerance and low warping to ensure consistent feeding and stable prints, good layer bonding, less stringing, no bubbles, no cracking, no deformation, easy handling, resulting in an outstanding surface finish and are highly precise.
