"Sounds like those 3D printers might come in handy.

What is Archimides best klnown for?
"According to Vitruvius, a votive crown for a temple had been made for King Hiero II, who had supplied the pure gold to be used, and Archimedes was asked to determine whether some silver had been substituted by the dishonest goldsmith.[16] Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body in order to calculate its density."
That was more than 2,200 years ago and those dishonest goldsmiths are still active and much better equipped today. Take care and never forget the "Caveat Emptor" thing.
