METHOD AND SYSTEM FOR PRECISION ADDITIVE PRINTING OF THREE-DIMENSIONAL STRUCTURES (EMBODIMENTS) Russian patent published in 2023 - IPC B29C64/124 G03F7/20 

FIELD: precision additive printing of three-dimensional polymer structures.

SUBSTANCE: invention can be used for manufacturing of optical elements for microscopy, high-resolution tomography, spectroscopy, and fluorescence spectrometry. A distinctive feature of the method is the construction of the initial 3D model of the manufactured microstructure in the XYZ coordinate system, the manufacture of a calibration sample at given optical parameters of the two-photon lithography exposure process, followed by determination of the average values of the semi-axes in the sample of ellipsoidal voxels, the division of the model into layers in the parallel XY plane, determination of coordinates of the centres of the boundary voxels relating to the surface of the original model at one point in each layer, formation of the trajectory of the laser beam in such a way that they do not go beyond the coordinates of the centres of the boundary voxels. A system for fabricating three-dimensional microstructures is also disclosed.

EFFECT: technical result consists in increasing the accuracy of the shape of the working surface of the manufactured structure.
