Abstract in different language:	The aim of this article is to introduce to the reader problems which is connected with processing of WC-Co composite material by the technology known as SLM (Selective Laser Melting Technology). The biggest problem associated with the material processing process is the porosity of the prototype builds. The work deals with what the final porosity of the product is affected by parameters of printing process and by raw material properties used for it. The presented results were obtained by performing metallographic analysis of builds made of various types of WC-Co powder mixtures under different processing parameters of them. Metallographic analysis was performed using light and electron microscopy techniques. These analyses were further supplemented by the evaluation of mechanical properties of prototypes by the test of hardness, compressive strength and dynamic resistance of the product by the impact test.
