Flashforge Flexible Natural is a premium TPU (Thermoplastic Polyurethane) filament with a 1.75 mm diameter, designed for applications requiring flexibility and durability. This material offers high elasticity, impact resistance, and oil resistance, making it ideal for functional prototypes, seals, phone cases, and protective components. The natural color provides a clean, translucent finish. For optimal results, print with a nozzle temperature between 200°C and 230°C and a heated bed temperature of 30–60°C. Adjust your extruder settings carefully to prevent clogging, as TPU is softer than standard filaments. A direct drive extruder is recommended to ensure smooth feeding. TPU is hygroscopic, so store it in a dry place to maintain print quality. While its versatility and strength are significant advantages, slower print speeds may be necessary for precision. Suitable for hobbyists and professionals alike, this filament delivers reliable, flexible parts for a wide range of projects.
