BPNX1017: 3D Printing of Functional Materials

Zhen Wang

2024

3D printing enables the fabrication of 3D functional materials with complex structures associated to various functionalities. Developing 3D printing resins with different properties promises to fabricate a myriad of complex functional devices with e.g., self-sensing, actuation, and structural elements assembled in a designed 3D layout. In this project, we explore the achievable property space and the material-performance correlation of 3D printing by designing a series of photo-curable resins. We unveil how the functional groups of the resins synergistically impact the...

2024

Piezoelectric hydrophones are crucial for underwater applications such as communication and seafloor mapping. Limited by the brittleness of piezoelectric ceramics, conventional manufacturing methods restrict hydrophones’ shapes to simple geometries such as disks, cylinders, or spheres, which limits the sensitivity, directivity pattern, and working frequency bandwidth of the device.

We are developping a new class of high-performance 3D printed piezoelectric hydrophones consisting of rationally designed micro-architectures. Using a high-...

2024

The rapid development of additive manufacturing technologies has enabled the fabrication of truss metamaterials, i.e., a novel class of lightweight-yet-strong materials with engineered complex hierarchical structures. Manipulating the architecture over chemical composition dramatically expands the achievable materials design space, allowing to largely control the mechanical response of metamaterials. Despite the great advances made in this area, designing three-dimensional (3D) truss metamaterials under complex or extreme conditions with programmable response is still a...
