Hi AE:
I don't know of any such machine myself, but that's not to say there isn't one
someplace. I think the only good possibility is to post your request to the RPML and see
what happens. I would also get in touch with Stratasys directly. One of their field people
might know where a machine is. I don't know whom to suggest at Stratasys, however. Start
with sales and see if you can make a case that your research will be a help to them down
the road.
Another possibility is for you to get some time on a machine at another university or
at one of the research institutes in the UK. There's a long list of those on our site and
definitely some have FDM. It would be best if you could offer to swap something for the
favor in return.
I'm afraid that it's very difficult to get something for nothing, but you may get
lucky. And I'm afraid that's what it takes.
Good luck,
Ed
