How do robots possess unique and controllable mechanical behavior? Multi material 4D printing gives you the answer!

The compression torsion metamaterial structure is an intelligent structure that converts axial compression into torsion. Due to its unique and controllable mechanical behavior, it has shown great potential for applications in multiple cutting-edge fields, such as flexible robots, intelligent folding structures, medical devices, etc.Multi material 4D printing technologyIt further releases its design freedom by integrating materials with different stiffness and elasticity into the same structure, achieving multiple properties and functions.
