Funny. I just sussed out this ad on gumtree that offered 3d printed copied boards finished for $350. I thought it was a scam. Ended up they can't copy your board. they already need the file. I'd be interested to know if anyone can as well. I've had mates with the latest shaping machines that have said they can 'scan' a board. They can't. there is still an element of hand measurement to get the file on computer. It never ends up the same http://www.gumtree.com.au/s-ad/byron-bay/surfing/surfboards-5-6-5-8-5-10-6-6-2-custom-made-for-you/1047772098
This may not be true... I am pretty sure you can 3d scan any thing... We have one at my work and no hand measures are needed you just need a reference point.. From that it creates a cad file which I guess you could send to the 3d printer
