Innovative Nanoscale 3D Printing in Photonics by Singapore University
Singapore, Saturday, 9 August 2025.
Researchers in Singapore have pioneered nanoscale 3D printing for photonic crystals, enhancing potential application in fields like applied physics, positioning Singapore as a leader in engineering advancements.
Advancements in Nanoscale 3D Printing Techniques
The Singapore University of Technology and Design (SUTD) is at the forefront of nanoscale 3D printing innovations, particularly in the creation of photonic crystals (PhCs). Utilizing a unique Glass-Nano resin, the process involves two-photon lithography (TPL) to polymerize the resin into microstructures. These structures undergo a heat treatment to form silica through the reaction of oxygen with silicon, forming sintered diamond PhCs with distinct optical properties [1].
Implications for Photonics and Engineering
This breakthrough enhances the applications of photonics in various fields, including telecommunications and data processing. By effectively manipulating light at the nanoscale, PhCs can potentially replace electrons in traditional electronics, leading to faster and more efficient technological solutions [1]. This capability indicates a significant stride in applied physics and engineering, signaling Singapore’s leadership in the development of novel technologies.
Positioning Singapore as a Leader in Photonics
The successful demonstration of this nanoscale 3D printing technology by researchers at SUTD reinforces Singapore’s position as a leader in photonics and advanced manufacturing. The precise fabrication process exemplifies the nation’s commitment to cutting-edge research and innovation. Such technological advancements not only attract global interest but also foster local talent and spark further industrial collaborations [1].
