Revolutionary 3D Printing Technique Boosts Nanostructure Production 1,000x

12/18/2025

Summary

Story summary

Researchers have developed a 3D printing technique using metalenses that enhances two-photon lithography for nanostructures.
The method increases throughput by over 1,000 times while maintaining 113-nanometer features.
An array of metalenses creates more than 120,000 focal spots, enabling parallel printing across large areas.
Potential applications include drug delivery systems and nuclear fusion research.
The findings were published in Nature on December 17, 2025.
