The brief overview of the principles of the atomizers, highlighting major shortcomings. an alternative method of production of specialized metal powder have been proposed for addition of laser technology - plasma treatment. The technique of the experiment the plasma treatment of the brand PMS-1 metal powder. According to the results of the research conclusions were drawn about the possibility of applying plasma processing to optimize the shape of the powder particles. Keywords Laser additive manufacturing, atomization, specialty metal powder, spherical particle shape, plasma treatment, spheroidization
