Producing replicas of artefacts is often touted as a solution to ownership disputes – both parties can have a version. Of course it then raises a question of who gets to have the originals. Or, if both are equal then why either party would mind not having the originals.

There are many copies of the Parthenon Sculptures, made from a smaller number of first generation casts, but if they are indistinguishable, then one has to wonder why the British Museum has from time to time proposed that Greece should be completely happy with casts, when they themselves are unwilling to give up the originals.

A copy has its own history from when it was made & how it was made, but this is a completely different history to that of the originals. As evidenced in many cultural property disputes around the world, provenance is critical in many different ways. A piece of rock from the moon, even if of identical composition to one on earth has an inherent importance because of where it originated and what we can learn from that.

That said, copies have their own value, in allowing people to study items from a physical artistic point of view more easily & the prevalence of 3D printing is going to make this sort of research more commonplace in future.

The British Museum allows some artefacts to be downloaded and 3D printed

3-D printer copying of sculptures: Is it legal?

Almost every physical object, from a spoon to Edgar Degas’ famous dancer sculptures, can be scanned and uploaded onto the Internet as a file, ready for download by anyone with a desktop 3-D printer. But like the digitization of music and books before it, the migration of objects of art and design online brings with it the baggage of America’s frustrating intellectual-property regime.

A cast of Michelangelo’s famous 16th-century sculpture of Moses sits on the campus of Augustana College in Sioux Falls, S.D. Jerry Fisher, who lives in the area, decided to create a 3-D printable version of the artwork using photogrammetry – analyzing 2-D photos of an object and turning them into a digital 3-D model.
