Astra Optics Limited, a pioneering startup spun out from The Chinese University of Hong Kong, is redefining the possibilities in nanoscale fabrication. Building upon the team’s groundbreaking research published in Science in 2019 [1] and 2022 [2], Astra Optics launched the world’s first multi-material nanoscale 3D manufacturing platform — the Femtosecond Projection NanoPrinter. This innovation sets a new benchmark for high-precision, multi-material, and rapid prototyping applications in both scientific research and industrial production.
Our Advantages
-
Multi-Material Compatibility
Compatible with over 15 material types—including metals, polymers, and biomaterials—enabling complex 3D micro/nanostructure fabrication across diverse applications. -
Ultra-High Resolution
The FP printing platform achieves a resolution as fine as 30 nm, while the Two-Photon Polymerization (TPP) platform delivers 140 nm lateral and 175 nm axial resolution. -
High-Speed & Cost-Efficient
Our FP technology overcomes the traditional trade-off between resolution and throughput, delivering printing speeds 1,000× faster than commercial systems while reducing costs by up to 90%.
