FlexLinks were developed for quick turn-around proof-of-concept prototyping of compliant mechanisms by the BYU Compliant Mechanism Research Group. Combined with commercial components from the LEGO Group, custom compliant components can be used to build a wide range of compliant mechanisms.
FlexLinks can either be 3D printed or cut out of polypropylene with a mill, CNC router, or water jet.

The FlexLinks can be 3D printed, milled, cut with a water jet, or cut with a CNC router. You'll get the best results cutting them out of polypropylene.
The cross-axis flexural pivots require TWO PARTS that are placed reversely on top of each other. If cutting them out of polypropylene, use a 1/8".
The FlexLinks can be 3D printed, but depending on the material used, there are limitations to flexibility and fatigue life.

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.
