from experimental design to analytic simulation.
The combined employ of the additive manufacturing approach with shape memory polymers (SMPs) is one of the possible strategies towards 4D-printing, in particular when aiming at the realization of highly effective shape shifting objects. SMPs are in fact active systems, capable of being temporarily fixed in a deformed configuration and to revert to the pristine shape upon application of a thermal stimulus. In addition, this response may be finely tuned by a proper combination of the thermo-mechanical history and of the material macromolecular architecture.

Material programming denotes a design method in which functions such as movement are encoded in the physical material and fabrication logic, in place of electronics and digital control. Plants respond to their surroundings because of their functionally graded internal structures — similarly, when materials are structured at the meso-scale, they can be programmed to change shape in response to the environment.

We designed and created the Tokyo 2020 Olympic and Paralympic 3D Printing Podium using recycled materials. Also, we are supporting its re-use program as acoustic metamaterials. In this presentation, we introduce our design and fabrication processes, and new ideas of re-cycle and re-use including metamaterial concepts.
