You should call Laser Innovations at 805-529-5864. They are using the
Spectra Physics laser, which is very reliable ~12,000 hours of life. I was
also able to get better through put on the SLA500 than our SLA5000.

  Dear RP professionals:

I have run a SLA-500 from 3D Systems Inc. for over 7 years.
In spite of its relatively good performance,some problems associated with
maintenance have always bothered me.
That's why I am almost determined to replace Argon gas laser with
I,however,am very afraid that the solid-state laser can not show such
reliability and performance as Argon gas laser does.
Is there anybody who has experienced solid-state laser replacement on
SLA-500 ?
I am in a desperate need of your precious comments before replacing laser.
Any comments you could give me would be greatly apprecited.
Thanx in advance.
