Re: 3D Printing of Sailboats
I could see it happening, but it will take a while longer than 10 years. I doubt anyone will go into business buying a large printer to print boats, but once you have the equipment it doesn't matter much what you make with it.
My guess is the first boats made this way will be aluminum, or actually titanium. As an outgrowth of metal sintering technology already being used in custom fabrication instead of making molds. But right now the largest machine I know of (not that I follow it closely) is only a few feet a side. But within this size pretty much anything can be made.
They would just have to up the size massively to make it possible.
