3D Printing Service

[Bill Weiler]

I have a small part I need made. (a 11mm wheel and pully for my Nanosumo robot). Is there a 3D printing service anyone likes they would recommend? It would be great to get around .1mm resolution if possible.

fastprotos.com is advertised in Servo FWIW.

I looked at fastpros, that Bob found, but their minimum feature size is .6mm and I definitely need .5mm. I emailed Techshop's 3dprinting email address yesterday asking for a quote, but I haven't heard anything. So I emailed Techshop's info email address, and no reply. Seems I should get some kind of confirmation. But maybe it is casual - not a ongoing profitable thing for them.

Bill,

I assume you already know of shapeways yes?

http://www.shapeways.com/

Their frosted detail plastic should exceed your detail specifications.

I am mostly sure that the frosted detail plastic is made on a projet. The same printer that techshop has.

I suspect you will pay less to get this printed at shapeways than you will techshop. It would be nice if you would report back.

I ordered 3 wheels on shapeways for $23. They warn that frosted detail plastic is brittle. This could be a show stopper if they break easily. Another option I thought is to make urethane castings in RTV from them, however, I have never done that before. With .5mm features, is it even possible? Would urethane be strong?

I called Techshop and they said their expensive 3D printer is down. They don't know when it will be fixed.

For what it's worth. I am 90% sure that the frosted plastic that
shapeways sells is made on exactly the same printer that is the nice
printer at techshop. That would be a projet SLA printer.

Good stuff. It is described as "acrylic like". In that , it's quite
hard and brittle. Just like acrylic.

You may find it works well for you.
