Indeed!
The only problem with it is that it is too slow. 2-20mm^3/s depending on the
metal and the geometry -  that's between 50grams and 500grams per hour, and
this thing probably has a hourly rate more than a high class hooker.

Was reading about one company, AeroMet, that proposed building reactor
containment vessels using this technique. Instead of layers of powder being
sintered, they would blow an stream of powder onto a surface and laser fuse
the stream at the focus point of the laser. With 20 of these
laser/metal/aerosol thingies on robot arms/gantries, they estimated they
could build a containment vessel in 8 months, complete with cooling cavities
etc etc etc.
