Researchers from MPI-IS and NUS have developed a light-driven 3D printing technique that moves beyond polymers. This breakthrough enables nanofabrication using metals and semiconductors, paving the way for advanced, multi-material robots and medical devicesScientists have reached a significant milestone in micro- and nanotechnology. For years, the ability to “print” complex 3D structures at a microscopic scale was largely confined to polymers. The power of optofluidic assembly: NanofabricationThe traditional gold standard for tiny 3D structures is two-photon polymerisation (2PP). By moving beyond polymers, engineers can now create tiny components with specific electrical, magnetic, or thermal properties.
