To SLA 250 user's,
We have a new SLA-250 with a Omnichrome 3074-20M laser. The problems
start when we reach 250 hours on the laser. It droped from 30 to 21 MWs.
After a remelt it was back up to 30 MWs. At about 500 hours, same problem,
solution and result. 3D Systems was made aware of the 2 remelts. Finally
at 750 hours when this started again, 3D Field Engineer did a PM. At 1100
hours I am back to 21 MWs. Also, the power varies 4 MWs during a build
cycle. I don't remember doing 3 remelts in the life time of my last laser,
which died at 7500 hours! Is any one else having any similiar problems with
their Omnichrome laser? I am told that the remelts does not effect the life
of the laser, but the lost of time doing remelts and slow build times are
starting to become bothersome. Then there is that horrorable smell that is
driving me crazy, which is really a short putt!
Thanks,
