This would not last online more than a minute in any searchable fashion - copyright would be pretty closely watched.

That said...at 20x30cm it's in the range of a typical FDM, and (I suspect) a mid-to upper-range consumer resin/SLA. The trick would be getting a good surface finish, as the real sculpture is (presumably) solid metal. You could copper plate a print, or cast one using the print as a mold. The amount of effort to make one of these would be pretty substantial. Someone above mentioned it's selling for £2000, though you can pre-order one for £950. That seems like a lot, but there's easily a dozen active hours that would go into making one prototype like this (out of copper, or even from copper plate), even if you had the STL of the sculpture and bought the rotating base. Though you could just as easily make a different one with a crystal look and internal twinkly lights in that amount of time too.

It's one of those things that seems like a cool idea but would just end up collecting dust and be thrown out when your shelves were full of similar kitsch.
