Researchers at Purdue University have developed a patent-pending single-photon 3D nanoprinting technology that enables the rapid and cost-effective creation of high-resolution nanostructures, outperforming traditional laser-based methods.

Led by Professor Liang Pan, the technology utilizes modified photocurable resin materials, allowing for lower laser intensities and faster printing speeds without the need for expensive femtosecond lasers.

This innovative approach significantly reduces tool costs—potentially by 10 to 100 times—using simple light sources like laser pointers.

The single-photon method can produce intricate nanostructures for applications in nanotechnology, manufacturing, and healthcare, demonstrating capabilities such as 120-nanometer resolution and parallel printing with multiple beams, as reported by The CW.

The team is seeking federal funding to enhance scanning throughput and further develop the technology, while industry partners interested in commercialization can contact Purdue’s business development manager for collaboration opportunities.
