1. A method for producing feedstock powder suitable for use in laser-based additive manufacturing, the method comprising:
directing a focused energy source toward a solid source material to vaporize compounds of the solid source material; and
passing the compounds through a temperature-controlled vaporization chamber to cool the compounds and form solid microparticles comprising the compounds.
