Just exploring a non laser related idea.
I was wondering is it easy / possible to precisely 3D scan an object then easily convert that into a profile that's the opposite of that which has been scanned?
eg. an egg and cup. You scan the egg top but can then reverse that scan to create a flat plane of a preset size with a cup shape in it that perfectly fits the egg.
Following on from that, it is then easy to 3D print that imprinted flat plane from that reversed CAD?
Any tips / hints on software needed?
