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 the 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. 
Our records have been internationally recognized by our 2019 and 2022 publications in the Science Magazine (Saha et al., Science, 366(6461): 105-109, 2019 & Han et al., Science, 378(6626): 1325-1331, 2022) with multiple U.S. patents. 
By substantially lowering the cost of micro-additive manufacturing, our product enables industrial scale application of TPL and multi-material 3D nanofabrication at 20-nm resolution for the first time. Our product will generate impact in different industries such as nanotechnology, biotechnology, healthcare, renewable energy, and electronics.
