Polymaker PolyFlex TPU-90A Klar 2,85 mm 750 g

Polymaker PolyFlex TPU-90A Klar is a high-quality, transparent filament based on thermoplastic polyurethane, designed for users seeking flexible materials with easy print settings. With a Shore hardness of 90A, this material offers a balanced mix of flexibility and strength, making it ideal for functional prototypes and durable parts. Its clear transparency allows for the creation of aesthetically pleasing objects where light transmission is desired, such as decorative elements or housing components. PolyFlex TPU-90A Klar is easy to process and compatible with most common FDM 3D printers. Recommended print temperatures are between 220°C and 240°C, while a heated bed at 0-50°C ensures good adhesion. Print speed should be moderate (20-40 mm/s) for optimal results. Strengths of this material include its high toughness, abrasion and oil resistance, and ease of handling compared to other TPU filaments. A limitation is that extreme stretching in thin walls can lead to material fatigue. Applications include seals, protective caps, flexible joints, and technical parts requiring some elasticity.
