Abstract: A radiation source assembly for an apparatus for layer-by-layer formation of a three-dimensional object by the consolidation of particulate material, the radiation source assembly comprising a plurality of radiation sources, each radiation source being operable to emit a respective beam of radiation towards a build bed surface of the apparatus and one or more collimators arranged to collimate the beams of radiation to produce one or more collimated beams of radiation and to direct said collimated beams of radiation towards the particulate material on the build bed surface.
