“…More efficient method is proposed by introducing a liquid cooling medium to change the form of heat exchange. Initially, the workpiece is deposited on a substrate with the lower half immersed in water [25], which can improve the quality of thin-walled parts with few layers. However, the cooling effect became gradually worse as the number of layers increased.…”

Wire arc additive manufacturing (WAAM) process is widely used in large steel components. However, WAAM severe heat accumulation reduced the accuracy of the products, its microstructure and mechanical properties also deteriorate. Compared with common steel, it is more difficult to get complicated stainless steel components with WAAM due to its weak heat dispersion. To efficiently mitigate the heat accumulation, this paper presented a water-medium active cooling additive manufacturing system to complete a 304 stainless steel thin-walled structure. As a result, taller and narrower thin-walled parts could be gotten with 7% increase in average height and 13% decrease in average width. Simultaneously, the surface waviness is reduced, grains are refined and fracture properties of thin-walled parts are improved.
