Abstract

A laser consolidation apparatus for manufacturing precise three dimensional structures disclosed. The apparatus comprises means for feeding a stream of material to an area on a surface to be built up, at an angle normal to the surface and means to direct a converging laser beam on the surface at an angle of 25 to 30° to the normal to the surface from a plurality of directions surrounding the material feed. Discrete mirror segments direct the laser beam on to movable plane mirrors producing reflected beams which combine to illuminate an area on the work surface.
