Print volume upscaling using multiple projectors in tomographic volumetric 3d printing

The present disclosure relates to a method for producing a three-dimensional object comprising: computing a plurality of subsinograms, wherein the subsinograms are derived from at least one sinogram describing the three-dimensional object to be formed from different orientation angles; providing a build volume comprising a photosensitive component capable of initiating a photochemical reaction upon irradiation by light of an activation wavelength; irradiating the build volume, by each of a plurality of projection units, with a projection of a series of patterns of light corresponding to one of the subsinograms, at the corresponding orientation angles, wherein the irradiating light comprises the activation wavelength, and wherein each projection unit irradiates the build volume with a series of patterns of light that is derived from a different subsinogram, such that the build volume is irradiated by a resulting series of patterns of light corresponding to the sinogram at the corresponding orientation angles.
