I'm very concerned about how fake meteorites made with 3D printers could dramatically alter meteorite values. Is this something that is already starting to happen? I don't know if 3D printers can make fakes YET. I do know that something shook me up that is in the current Astronomy magazine on page 13 (April 2013) It stated that 3D printers can create small objects out of synthetic Moon rock material.
Several weeks ago I posted my concern about 3D printers on the Off Topic Observatory but the vast mojority of responders only had high praise for these gizmos. Is there any concern at all from meteorite collectors?
I believe 3D printers use a special resin which will melt at a low temperature compared to a rock. Just apply some heat to the meteor in question the resin should melt when tested.
