Even if you buy a printer you should be aware of all the services. It might be more expensive but it opens up a lot more options too. Want a SLS print instead - they have it. Want to mill it from steel and then bend it - they can do that for you. Want to make something out of solid wood, no problem. Need a lot of parts fast - they have many printers and overnight shipping (at extra charge).

Sure it costs more, but if you will only do it once that is still cheap. And some of the things they can do for you are not safe to do at home.
