Nanoscale 3D-printed Microstructures by Nanoscribe
Using direct laser writing (DLW), german technology company nanoscribe have integrated the means of photonic professional laser lithography systems to create three-dimensional printed forms in nanoscale. the unique ability to structure in 3D with sub-micrometer sizes opens the door for rapid prototyping applications in areas such as 3D photonics and biomimetics, micro-fluidics and mechanical micro-structures.
Note: A micrometre or micrometer (pron.: /ˈmaɪkroʊmiːtər/, symbol µm) is an SI derived unit of length equaling 1×10−6 of a metre (SI standard prefix “micro-” = 10−6); that is, one-millionth of a metre (or one-thousandth of a millimetre, 0.001 mm, or about 0.000039 inches). The symbol µm is sometimes rendered as um if the symbol µ cannot be used.
