Effect of 3D-printed sand molds on thesoundness of pure copper castings in
the vicinity of as-cast surfaces

Journal of Manufacturing Processes 77 (2022) 329–

Although the use of three-dimensional (3D)printed sand molds enables both the formation ofnear-net shapes and the manufacture of ultra-highmix and ultra-low-volume pure copper castings,
detailed clarification is required regarding thecorrespondence between the use of such molds andthe generation of casting defects. In this study, theeffects of 3D-printed molds on the soundness of purecopper castings in the vicinity of as-cast surfaces
were investigated.
Experimental results showed that the adequate
deoxidization of the melt and the rapid formation ofa solidified shell after pouring are effective inenabling the utilization of 3D-printed molds and that㸫㸫
