Innovative Hybrid Nanocomposites in 3D Printing for Functional Applications: A Review.

Abstract

3D printing has garnered significant attention across academia and industry due to its capability to design and fabricate complex architectures. Applications such as those requiring intricate geometries or custom designs, including footwear, healthcare, energy storage, and electronics applications, greatly benefit from exploiting 3D printing processes. Despite the recent advancement of structural 3D printing, its use in functional devices remains limited, requiring the need for the development of functional materials suitable for 3D printing in device fabrication. In this review, we briefly introduce various 3D printing techniques, including material extrusion and vat polymerization, and highlight the recent advances in 3D printing for energy and biomedical devices. A summary of future perspectives in this area is also presented. By highlighting recent developments and addressing key challenges, this review aims to inspire future directions in the development of functional devices.
