The parallelised write process, photo-chemical polymerization interactions and associated diffusion phenomena were modelled via digital simulations written in MATLAB, based on Point Spread Functions (PSF) calculated using the PSF Generator software with the Gibson-Lanni model. The PSF represents the 3D light intensity distribution of the laser beam in the objective focal plane. Our software models the DOE generated light spot array as a 3D matrix of PSFs (Fig. ).
