Astra Optics Limited, founded by a team of experts in optical engineering, material science, and nanomanufacturing, is a spin-off company from the Chinese University of Hong Kong. Our ground-breaking 3D nanofabrication technology, i.e., femtosecond projection laser patterning system and hydrogel-based multi-material fabrication platform, has proven records to revolutionize the micro-additive manufacturing industry by overcoming critical bottlenecks in current state-of-the-art solutions, namely, low-throughput (~0.1 mm3/hr) and high fabrication cost ($20/mm3). The FP NanoPrinter is the only truly scalable nano-printing solution that simultaneously demonstrates record resolution (20 nm), throughput (100s mm3/hour), and substantially reduced cost ($1.5/mm3), which is three orders of magnitude faster than existing commercial methods.
