My current company - Formlabs. I get to build really good hardware (3D printers), working with ~seven different engineering disciplines. Smart people, high levels of autonomy, and very little politics. People are there to build great stuff.
If you don't mind my asking, what field are you in? I've been fascinated with 3d printing for a while(built my own printer etc) but haven't quite found the right place to apply and you are certainly selling the formlabs experience!
We do Software (embedded, desktop, web), mechanical, electrical, process, systems, optics, and manufacturing engineering. It's a pretty fun mix.
Since you asked, I personally work directly with all of the above (as a product lead). My expertise is in software, mechanical, process, and systems engineering.
