The Holiday Break

The Holiday Break

How strong is a Markforged-printed Onyx™ part with continuous fiber reinforcement (CFR)? Our Simulation software knows — do you?


Enter your best guess on how much force this 3D printed Onyx lever (reinforced with continuous carbon fibers) can withstand before it snaps.


Enter the contest by submitting your guess below. The party who submits the closest guess will win a Desktop 3D Printer.


This contest is now over and results will be posted soon.

How are we pulling this off?

Using the Instron® machine, the right side of the lever is attached to the test fixture with two thru bolts. The left side of the lever is pulled vertically by the Instron® crosshead via the chain until the part breaks and can no longer carry any load.
