Tough and fatigue resistant
FPU 50 is an impact, abrasion, and fatigue resistant semi-rigid material that is a good choice for parts that must withstand repetitive stresses such as living hinges or friction fits. FPU 50 is mechanically comparable to polypropylene.

Example Applications
These applications combine a need for toughness and fatigue resistance, in addition to isotropy, great surface finish, and accuracy.
Snap fit bands
Snap fits require toughness and fatigue resistance to maintain their connection over time, in addition to isotropy, smooth finish, and ability to print fine features.
Mounts
Mounts, like this camera mount, require toughness and fatigue resistance to maintain their mechanical linkage, in addition to isotropy, smooth finish, and ability to print fine features.
