  • Patent number: 12208569
    Abstract: The present disclosure relates to a method for performing an additive manufacturing operation to form a structure by processing a photopolymer resist material. A laser beam is directed at a tunable mask. At least one emergent beam is collected from a plurality of emergent beams emerging from the tunable mask. The at least one emergent beam is collimated to create a collimated beam. Each emergent beam from the tunable mask has a plurality of beam lets of varying or identical intensity, and each beam let emerges from a unique subsection or region of the tunable mask. The collimated beam is focused into a laser beam which is projected as an image plane onto or within the photopolymer resist material, such that the same optical path length is created between the tunable mask and the focused image plane for all optical frequencies of the focused laser beam.
