The paper presents an analysis of manufacturing methods of material-saving products in relation to investment castings and sintered powder technology. Surface microgeometry, shape accuracy, performance parameters, manufacturing costs and energy consumption were taken into account to make the optimal choice. The analysis was conducted by comparing test results for sintered powder products based on Distaloy AB alloy that consists of 0.55% C, 1.5% Cu, 1.75% Ni and 0.5% Mo and investment castings made of high alloy cast steel and nodular cast iron. The analysis made it possible to choose the best technology, considering also the ecological aspect.
