The charm of details

We have a new device at PW, offering unprecedented opportunities - it is the Nanoscribe Photonic Professional GT2 printer that enables for manufacture of high-resolution 3D objects. The device utilises the phenomenon of two-photon absorption, in which a duo of photons takes part in polymerising an individual chemical particle. By putting in specific settings of the laser, the researchers are capable of curing the polymer only within the laser stream. The smallest shape that this method enables to be cured is a voxel, which can be treated as a counterpart of a pixel on 2D screens.
