Apparatus for manufacturing a component by added layer deposition and a method of manufacturing a component. The method comprises the steps of directing a beam of energy e.g. a laser beam to heat a working region of a substrate and adjusting the cross sectional shape of the beam to thereby generate a variety of predetermined cross sectional shapes of working region while the beam is being directed onto the substrate. Thus the distribution of energy delivered to the substrate is controlled during the manufacturing process. The cross sectional shape and area of the beam is repeatedly monitored and compared to a library of predetermined cross sectional shape(s) and area(s) and the beam cross sectional shape adjusted accordingly. |
