Large-scale additive manufacturing as direct laser melting makes it possible to produce significantly stronger structures than those produced using standard 3D printing. Copper alloys are promising in terms of their properties. The high thermal conductivity of copper has led to its application in various kinds of heat exchangers, furnace designs for arc melting of such active metals as titanium, zirconium, refractory metals. Water-cooled molds, pallets, and crystallizers are made of copper, which provide intensive heat removal from the melt. Despite their wide application, there is a small amount of data and research for direct metal melting technology when talking about copper alloys. This work is devoted to the study of the features of the formation of single tracks depending on the processing parameters, as well as the study of their geometric parameters to determine the possibility of manufacturing products from such materials. It was found that among the tracks obtained by direct laser melting there are stable regimes in which geometric parameters are preserved, the patterns of the manufacturing process are revealed. The influence of processing parameters on the geometric dimensions of the tracks is discussed. Based on the selected regimes, a three-dimensional object of primitive shape was created. It demonstrates the possibility of creating such products. Defects (pores and cracks) have been identified and the possibilities of their elimination have been determined.
