A DLP projector apparatus (10) for projecting a monochromatic display comprising a plurality of monochromatic light sources (111-113). The DLP projector (10) being adapted to radiate from each micromirror of its DMD chip (100) an image comprising a plurality of radiated locations which are shifted with respect to each other. The DLP projector apparatus (10) comprising a controller unit that is adapted to control the radiation from the plurality of light sources (111-113) to the image according to a radiation scheme in an object production file. The DLP projector apparatus (10) is also provided with an imaging table (240) that is adapted to be moved in a plane perpendicular to an imaging beam of the DLP projector apparatus (10). The movements of the table are coordinated and synchronized with the imaging scheme of the DLP projector apparatus (10). The imaging scheme and the movements of the table are controlled according to a radiation scheme in an object production file.
