APPARATUS FOR LASER CONSOLIDATION AND MANUFACTURING

摘要

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 norma l to the surface and means to direct a converging laser beam on the surface at an angle of 25 to 30.degree. to the normal to the surface from a plurality of directions surrounding the material feed. Discrete mirror segments direct the laser bea m on to movable plane mirrors producing reflected beams which combine to illumina te an area on the work surface.
