Quoted from Pablomck:yes, that's what most people think. printing something this size won't fit on most FDM printers. I happen to have a more expensive Type A, that can accommodate it, so that was my original plan. However, here are the problems. I want to print at a higher density and resolution for strength and finish. When you print something that large it cools before you loop around (a problem), send problem even with a raft it won't stick consistently, so it's no fun when it takes a day or more to print something this big and then you print messes up and you have to start all over again. Another issue is supports. If you have one head, which most do, then you are printing supports. On a piece this big a real PITA to cut away. So the options are $30K printer that can do two materials (so you can wash support material away) or SLS. either way there are some economy's with doing more at the same time. no change of material and you can print as many that will fit at once, thus saving time. That doesn't even figure the time in high end scanning and throwing away cause just too many holes to close, and then starting from scratch with CAD (many hours of getting the splines just right). So with current services prices this gun is prices as cheap as I can get it., with really no mark up (go check out the prices yourself). Hopefully this will continue to come down in price, so if you don't need it now, wait it out.
I know the services are expensive which is why I figured that you were going that route based on price...
but a friend of mine bought a dual head printer for much less than $30k... the ultimaker 2+ has dual heads, can do 8.78 x 8.78 x 8.07 in, 300mm/s and 0.02mm layers and is less than $3k
