Abstract
An additive manufacturing apparatus including a build chamber in which an object is built and a flow device. The flow device comprises a body having a Coand{hacek over (a)} surface and a passageway connectable to a pressurised gas source. The passageway has an opening located adjacent to the Coand{hacek over (a)} surface to, in use, direct a jet of gas over the Coand{hacek over (a)} surface. A space adjacent the Coand{hacek over (a)} surface is in fluid communication with the build chamber such that gas drawn into and/or propelled from the space causes gas flow through the build chamber.
