3-D inks that can be erased selectively: Scientists develop method for the specific degradation of laser-written microstructures

3-D printing by direct laser writing enables production of micro-meter-sized structures for many applications, from biomedicine to microelectronics to optical metamaterials. Researchers have now developed 3-D inks that can be erased selectively. This allows specific degradation and reassembly of highly precise structures on the micrometer and nanometer scales.
