Fiberlogy FiberFlex 40D Pink
Fiberlogy FiberFlex 40D Pink is a print-friendly flexible filament with a Shore hardness of D40.
Fiberlogy FiberFlex 40D Pink (pink) is a flexible filament that allows you to easily create rubber-like prints. With a Shore hardness of D40 on the Shore scale (comparable to, for example, skateboard wheels), you can print at speeds up to 45mm/s with a direct drive extruder (15-30 mm/s for a bowden setup). The filament is easy to feed and the layers adhere very well to each other. 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 strength. You will discover that printing with flexible filament doesn't have to be difficult.
Fiberlogy is known for its premium quality filament that meets the highest quality standards and goes beyond other manufacturers. By maintaining a diameter tolerance of 0.05 mm and a roundness tolerance of 0.02 mm for flexible filament, FiberFlex 40D distinguishes itself from the rest and allows you to get the best out of your 3D printer.
