The interesting part is that the process is not fusing the structure and keeps it, mostly intact. Normal electroplating would fuse the surfaces with a layer of metal, rather than keeping the foam structure. The problem here would be repairing big breaks though. Plus maybe working with metals that do not readily work in electroplating bath, like aluminium.
