Quality improvement problem has been considered for a laser sintered surface layer. Purposely built experimental setup was decribed together with a four-factor experiment design on laser sintering PMS-1 copper powder. A mathematical model describing the effect of laser sintering process parameters on the surface roughness has been proposed. Practical recommendation for improving the quality of the surface layer is given.
