【 摘 要 】

The use of 3D printing methods in the industry is becoming more frequent and popular. It brings specific economic effects, enables quick and precise production of machine parts and devices. The article presents a fragment of research carried out in the Welding Engineering Department of the Warsaw University of Technology on the application of MAG arc welding for 3D printing. The MAG method was used to try to produce thin walls. The aim of the presented research was to determine the effect of the cooling method on shortening the time of manufacturing the 3D model of thin walls. The models were made using G3Si1 and 316LSi electrode wires. In the first part of the research,an interpass temperature of 50 °C, 100 °C and 150 °C, achieved by free cooling was adopted. In the second part, the interpass temperature was 100 °C and was achieved by forced cooling with a copper plate, a fan and a stream of compressed air. The greatest reduction in the time of manufacturing the 3D model of a thin wall was obtained for cooling using compressed air.
