Definitions

  • DED directed energy deposition
  • - depositing material for example jets of powders, in particular metal powders obtained from one or more metal materials, on a working area;
  • a movement of cyclic oscillation is imparted on the laser beam, substantially corresponding to a movement of precession, where in each cycle of such a movement of precession the focusing spot of the laser beam describes the pre-set pattern, for example chosen from among a circular pattern, an elliptical pattern, a linear pattern, and a pattern shaped like a figure 8.
  • the above list of patterns is presented purely by way of example in so far as the solution discussed herein teaches how to use any further pattern suited for imparting a dynamic movement to obtain a width of the trace equivalent to the one that would be produced by an apparent spot having a width substantially corresponding to the width of the trace so that the depth and the width of the trace obtained can be decoupled.
  • FIG. 2 is a view of an additive-manufacturing system
  • the above catenary may possibly deliver also process gases, such as argon or nitrogen, for the melting process.
  • the above catenary comprises conduits for delivering the melting powders from respective supply devices arranged remotely with respect to the machine 10.
  • the above catenary comprises electrical control cables and possible tubes for delivering coolant.
  • this shows a view at an enlarged scale of the terminal part of the conduit 12e and of the tool-holder frame 30 of the head 12.
  • the pressurized conduit 12e is secured with respect to the top part 12a, whereas the frame 30 is, instead, associated to the bottom end of the conduit 12e in a way rotatable about the longitudinal axis of the conduit 12e, which corresponds to the main vertical axis of inertia of the frame, if understood as disk or ring.
  • Actuation means maybe arranged, in this case, within the conduit 12e for rotating the frame 30.
  • the resulting“illuminated” portion transmits to the powders a power having a distribution equal to the one resulting from translation of a shaped spot or“apparent spot” of a size corresponding to the amplitude of the oscillation imparted on the laser beam.
