Abstract
A system of optical monitoring and diagnostics of selective laser melting process with alternative beam power density distributions is developed. The experimental work with input parameters variation showed the correlation between obtained power density distribution and geometrical parameters of single tracks. Technological gaps of stable track formation for different distributions have been detected, and high-speed process photography have been realized.
