Fiberlogy FiberFlex 40D Beige
Fiberlogy FiberFlex 40D Beige is a print-friendly flexible filament with a Shore hardness of D40.
Fiberlogy FiberFlex 40D Beige is flexible filament that allows for easy printing of rubber-like prints. With a hardness of D40 on the Shore scale (comparable to, for example, skateboard wheels), you can print with a direct drive extruder at speeds up to 45mm/s. (For a bowden setup, 15-30 mm/s is recommended). The feed is easy and the layers adhere extremely well. Thanks 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 and allows you to get the best out of your 3D printer.
