Fiberlogy FiberFlex 40D Black
Fiberlogy FiberFlex 40D Black is a print-friendly flexible filament with a Shore hardness of D40.
Fiberlogy FiberFlex 40D Black (black) is a flexible filament that allows you to easily create rubbery prints. With a hardness of D40 on the Shore scale (comparable to, for example, skateboard wheels), you can print at a speed of up to 45mm/s using a direct drive extruder (for a bowden setup, 15-30 mm/s). The filament is easy to feed and the layers adhere extremely well. Due to its user-friendliness, FiberFlex 40D can be used for both amateur and professional applications. FiberFlex 40D filament can withstand lower temperatures, is wear-resistant, and has high impact resistance. You will discover that printing with flexible filament doesn't have to be difficult at all.
Fiberlogy is known for its premium quality filament that meets the highest quality standards and goes beyond other manufacturers. By maintaining a diameter tolerance for flexible filament of 0.05 mm and a roundness tolerance of 0.02 mm, FiberFlex 40D distinguishes itself from the rest of Fiberlogy's products, allowing you to get the best out of your 3D printer.
