FiberFlex 40D
Flexible 3D Printing Filament
Fast and precise? Yes, it’s possible. FiberFlex 40D proves it. This flexible filament (flex) with a Shore hardness of 40D allows 3D printing at speeds up to 45 mm/s without compromising print quality. What’s more, with FiberFlex 40D you’ll discover that flexible 3D printing doesn’t have to be difficult. Feeding it into the extruder is smooth and easy, and each layer bonds perfectly with the next. Your 3D prints will also feature excellent properties such as high impact resistance, resistance to low temperatures, chemical resistance, and abrasion resistance. This makes FiberFlex 40D suitable for both hobby and professional applications. The filament also comes in a variety of colors, making it easy to find the perfect match for any project.
