1. A device for producing a three-dimensional object from a solidifiable material, comprising: an image forming unit comprising a number of image forming elements arranged in a two-dimensional matrix, wherein during an object building operation, each image forming element projects a first solidification energy onto a surface of the solidifiable material, thereby projecting a first set of pixels on the surface of the solidifiable material, the first set of pixels defining an image pattern at a first position and each pixel in the first set of pixels corresponding to one of the image forming elements, and each image forming element projects a second solidification energy onto the surface of the solidifiable material, thereby projecting a second set of pixels on the surface of the solidifiable material, the second set of pixels defining the image pattern at a second position shifted relative to the first position, and each pixel in the second set of pixels corresponding to one of the image forming elements.
