Ask HN: Looking for 3D printing startups in the UK

I'm giving a talk on my expereince developing Formlabs' Fuse 1 SLS printer at a conference in Birmingham next week. I have a couple of days (Sept 29 - Oct 1) after the conference and I'm looking for any interesting hardware or 3D printing companies that might not have a lot of attention yet who could want to meet up for a chat. London would be best, but happy to go somewhere else in the UK for a good reason. If you or someone you know fit that description let me know - my email is eduardo at formlabs.
