FlexLinks: Fixed-Fixed Beam - Quarter Circle

Summary

FlexLinks were developed for quick turn-around proof-of-concept prototyping of compliant mechanisms by the BYU Compliant Mechanism Research Group. Combined with commercially available toys, custom compliant components can be used to build a wide range of compliant mechanisms.

How to make it

The FlexLinks can be 3D printed, milled, cut with a water jet, or cut with a CNC router.

Depending on the material used, there are limitations to flexibility and fatigue life. You'll get the best results cutting them out of a 1/4" sheet of polypropylene.

There are many other types of FlexLinks that we've designed. There are different designs with different functions and lengths that you can experiment with.

This design was developed by the Compliant Mechanisms Research Group (CMR) from Brigham Young University (BYU). Follow us at @byucmr on Instagram or visit the BYU Compliant Mechanisms Research (CMR) website to learn more about compliant mechanisms.
