Abstract: A selective laser solidification apparatus including; a powder bed onto which powder layers can be deposited, at least one laser module for generating a plurality of laser beams for solidifying the powder material deposited onto the powder bed, a laser scanner for individually steering each laser beam to solidify separate areas in each powder layer, and a processing unit. A scanning zone for each laser beam is defined by the locations on the powder bed to which the laser beam can be steered by the laser scanner. The laser scanner is arranged such that each scanning zone is less than the total area of powder bed and at least two of the scanning zones overlap. The processing unit is arranged for selecting, for at least one powder layers, which laser beam to use to scan an area of the powder layer located within a region wherein the scanning zones overlap.

Abstract: A selective laser solidification apparatus including: a powder bed onto which a powder layer can be deposited, a gas flow unit for passing a flow of gas over the powder bed along a gas flow direction, a laser scanning unit for scanning a laser beam over the powder layer to selectively solidify at least part of the powder layer to form at least one object and a processing unit for selecting a scanning sequence of the laser beam based on the gas flow direction.
