Evolution of a crack during melting of CMSX-4 powder over multiple layers. (a)–(e) A fully open crack that gets closed during melting, followed by a complete reopening during solidification. The release of tension during crack reopening induces spatter particle ejection [panel (d)]. (a′)–(c′) A partially closed crack is further closed during melting and remains in that partially closed state after solidification. (a′′)–(c′′) The crack has fully disappeared and does not reappear upon melting and solidification. For each layer shown, a video of the full layer melting procedure is provided in the supporting information.
