Some research results of the developed technology of rapid prototyping are presented. Two schemes of process realization are discussed. First scheme lies in laser sintering of the powder material layer after its compressing with rollers, second – in material sintering at powder injection into the zone of laser irradiation. As a basic material for products’ manufacturing, different powders based on Ni, Co, Ti and others were studied. Numerical experiments and their planning were used to find the optimal working conditions. It was found that to increase the productivity and processing quality, without introduction of additional energy sources, the most efficient way was to apply the additional scanning of the focused laser radiation within the limits of the focused spot.
