Karl,
Thanks for the info. I am glad to hear the DuPont, Lyconix upgrade is
going well for these unknown folks. I hope to find out more in the near
future.
Maybe someone will present a paper at the SLA User's Conf?
On the other hand, I am concerned that your gas lasers are only lasting
4000 hours. We must be really lucky! Maybe you should do what we do?
Cut the power in the middle of the build every other day!
I have a question for other SLA-500 user's, how many hours do your lasers
last?
Thanks,
Jim
