I was just watching some demo videos on 3d printers using 27 micron stainless steel and if you have the cad file you will be able to print your parts in 3d. They will be selling units under $1000 soon. looks like plastic and rubber parts will be easy if you can get the cad file. So if you can't find just make it at home.

What is soon?

Our 3D plastic printer was about 30K, and is on the low end. All the plastic ones in the DIY section are pretty coarse. Now the powdered titanium ones are kick ass! We priced them out at ~150 to 300K!

You build the file, upload and they print it.
Not only that, others can buy your design, and you get a cut of the sale!

For designing and prototyping, OK. For real use parts made of originally specified materials, not so much.

I looked into these as the looked like a great way to work on a few projects. Unfortunately, the consumables and raw materials cost don't make them very cost effective. If you just need one, and you only plan to make them, the over all cost makes them quite expensive. Traditional manufacturing methods are cost effective, you just need to do it in a quantity that makes sense.
