Marchy is a flexible product, design to be used outdoors and beat up through extensive performance in the elements, which begs the question:
How many times can it bend?
Testing Rig
This torture-testing rig is built from a modified Pastamatic filament re-spooling machine, featuring electric motors. a variable switch, gear reductions, and a plethora of custom parts. The power delivery has been routed through a central sprocket into a double cam that deflects the Marchy-mouthpiece assembly 12-15 degrees.
The double cam rotates at 64RPM under load, inflicting a total of 7680 bends per hour on the assembly. This is fast enough to demonstrate long-term fatigue, yet slow enough to not introduce excess heat into the part from deflection.
The result of 15,000 bends was a slight material deformation, which would not have any meaningful effect on Marchy and its usability. To date, Marchy has yet to be subjected to a fatigue-induced material failure.
