Toughness Enhanced PETG FilamentGood toughness that not easy to break, high purity environmental raw material leading smooth extrusion continuously fluent flow and no clogging. Strong adhesion and low shrinkage of 3D Printer Filament allows smooth first printing layer. High Precision. Excellent Clarity & Light Transmission. High Gloss. Excellent Impact Strength. Complete Functional PETGPETG not only has the advantages of high toughness and good mechanical properties (like ABS), but also has the characteristics of ease of print and minimum warp (like PLA). Suitable for printing functional parts that needs higher toughness. Clog-free & Bubble-Free & Less-tangleFull mechanical winding and strict manual examination to avoid any tangling issues.No overlap or tangle, no clogging and no cracking, printing models that have smooth and stable surface finish. High CompatibilityCompatible with most of FDM 3D Printers. Recommend PETG filament extrusion / Nozzle temperature 250
