Fiberlogy FiberFlex 40D Purple
Fiberlogy FiberFlex 40D Purple is a print-friendly flexible filament with a Shore hardness of D40.
Fiberlogy FiberFlex 40D Purple is flexible filament that allows you to easily create rubber-like 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 with a direct drive extruder (for a bowden setup 15-30mm/s). The feeding is simple and the layers adhere incredibly 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 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 0.05mm and a roundness tolerance of 0.02mm, FiberFlex 40D distinguishes itself from the rest of Fiberlogy's products, allowing you to get the best out of your 3D printer.
