Abstract

Selective laser solidification apparatus (2) is described that comprises a powder bed (6; 200; 300) onto which a powder layer (400; 500) can be deposited and a gas flow unit (30) for passing a flow of gas over the powder bed along a predefined gas flow direction (G). A laser scanning unit (20) is provided for scanning a laser beam (22) over the powder layer (400; 500) to selectively solidify at least part of the powder layer (400;500) to form a required pattern (402; 502). The required pattern (402; 502) is formed from a plurality of stripes or stripe segments (S1-S12) that are formed by advancing the laser beam (22) along the stripe or stripe segment (S1-S12)in a stripe formation direction (L). The stripe formation direction (L) is arranged so that it always at least partially opposes the predefined gas flow direction(G).A corresponding method is also described.
