ABS+ FilamentCCTREE ABS+ Filament is an enhanced version of Ordinary ABS. Cracking and warping have been significantly improved when printing large-sized items. It has high strength, better toughness, excellent impact strength, wear resistance, and heat resistance Stable Dimensional ToleranceMinimum tolerance and low warping to ensure consistent feeding and stable prints, good layer bonding, less stringing, no bubbles, no cracking, easy handling, resulting in an outstanding surface finish, and are highly precise. Diameter 1.75mm, dimensional accuracy + / - 0.03 mm High CompatibilityStrong and durable ABS+ filament is engineering thermoplastic. Suitable for printing parts with higher heat resistance requirements, such as industrial machinery parts, model machinery, electronic appliances, and instrumentation. CCTREE ABS+ Filament Compatible with Most of Enclosed FDM 3D Printers Recommended Print ParametersNozzle: 240C - 250C; Bed: 90C - 100C; Speed: 30mm/s - 50mm
