Surely a scan would only be the outside of a completed model? I suppose someone could scan the sprues and sell the parts, but who would buy them - that would be dearer than buying the kit.It do raise questions. One guy buys a kit, then either builds and scans it or just scans it then sells the scan cheap to anyone with a printer - so the original manufacturer sells one kit instead of 20; 50; 100 ...... Wonder how long they are going to be able to stay in business?
And with the increasing range of materials that can be printed, the whole of the manufacturing sector could be under threat - except of course for the ones who make printers!
Huxley never saw this in his 'Brave New World'.
Personally I don't think 3D printing (or any other form of additive manufacturing) will see the end of injection moulded kits, but it will probably have a big impact on resin figures and aftermarket accessories.
