Nano Scale 3D Printer

摘要

Nanoscribe is offering a 3D printer that is capable of building objects measured by the micron. The new Photonic Professional GT system uses laser lithography and two-photon polymerization to build sub-micrometer polymer structures. The build envelope of the Photonic Professional GT is limited to lOOu objects, but these can be fused together to create larger structures. 'A tremendous speed-up of the writing process is driven by an embedded ultra-high precision galvo technology, which laterally deflects the laser focus position by use of a galvanic mirror system. Thus, the fabrication of large area 3D micro-and nanostructures is now feasible in the shortest time,' notes the Nanoscribe website. 'In addition to rapid x-y-beam-scanning, a piezoelectric scanning stage provides ultra-precise x-y-z-movements of the substrate relative to the laser focus position...'
