Will any beta testers of the Fuse 1 be in attendance at the User Summit in May? I realize you may be limited on how much you can say, but I’d love the chance to chat.
I may be wrong, but I don’t think there is such an animal (a FUSE 1 beta tester).
Does ANYONE have a FUSE 1 (other than FormLabs that is)?
If there are they are probably be under NDA so you won’t get an answer here 
I would love to know more about the machine as well, but judging by the lack of news the guess that they have met major production/engineering blockers is still a valid one.
From the images I have seen surface finished looked a little rough compared to the ‘competitors’. It has not dampened my excitement for the FUSE 1 though.
