They exist, you just have to know what to look for! :) Libraries are increasingly getting 3d printers which you can use. I was at a space yesterday called Hatch in Boston that is totally free and volunteer run.

There are monthly subscription based spaces such as Artisan's Asylum[1] in Cambridge, MA that are full of all the equipment you could possible need for larger projects. They are also great because being surrounded by other makers is great conversation!
