Professor Chen Shih-Chi and his team at the Department of Mechanical and Automation Engineering have been presented the influential 2018 R&D 100 Awards, famously hailed ‘The Oscar of Invention’ for developing the Digital Holography-based 3D Nano-Builder. Pushing the envelope of single-point scanning in traditional 3D printing, the Nano-Builder employs revolutionary random-access scanning that allows tens of laser foci to simultaneously write structures at high speed. The nano-prototyping is most suited for applications in research and development, such as printing photonic, robotic, metamaterials, micro-scaffolds and drug delivery devices. As the focal point can be moved to anywhere in space, complex overhanging structures can be printed without supporting structures. Moreover, the modular design of the Nano-Builder enables its turning into a two-photon excitation microscope, whose femtosecond lasers can stimulate cells, such as that in mouse brains or zebrafish, with precision and accelerate discoveries in medicine and science.

With a robust innovation culture, CUHK encourages inter-disciplinary interactions and industrial partnerships with the aim of promoting knowledge transfer and creating positive economic and social impacts. A full range of resources and support, including consultancy service, training and networking opportunities with potential investors and mentors have been provided to Professor Chen’s team to facilitate commercialisation of his invention.

About R&D 100 Awards

The annual R&D 100 Awards identify and celebrate top technology products of the year worldwide. Many awarded technology breakthroughs have later become household names, such as the instant color process film, Polaroid, (1963), lithium batteries (1971), LCD, (1980) and the artificial retina (2009), among many others.
