The achievements of the two-photon polymerization based world’s highest resolution 3D micro-printer will be presented. The device offers a defined control on the feature sizes and resolutions ranging from nanometer to micrometer scale and accessible print area of ~ cm2. This versatility has opened new frontiers in the field of microfluidics, photonics, biomedical engineering, plasmonics, micro-optics, mechanical metamaterials, biomimetics, life sciences, and micro-robotics. All this is made possible by the advancements in the software and hardware design of the printer that enables the realization of ideas only with few clicks. The decade of trusted use of this technology has found its way in labs like Imperial College London, Harvard University, University College London, ETH Zurich, University of Oxford and to several industrial applications as well.
