Free-space direct nanoscale 3D printing of metals and alloys enabled by two-photon decomposition and ultrafast optical trapping

Nature Materials, Published online: 21 August 2024; doi:10.1038/s41563-024-01984-z

A polymer-free 3D printing technique of metals and alloys, using two-photon decomposition and optical force trapping, is presented. It achieves dense and smooth nanostructures with a resolution beyond optical limits.Nature Materials, Published online: 21 August 2024; doi:10.1038/s41563-024-01984-zA polymer-free 3D printing technique of metals and alloys, using two-photon decomposition and optical force trapping, is presented.
