What are the options for replacement lasers and subsequent service.
We have a SLA 250-30. Our original laser didn't drop below 30mw for several
months and was at 19mw when it died after 6000hrs. 3D Systems wants to replace
it with a 25-29mw unit saying they only guarantee 20mw on replacements. Note -
we like to run 5149 for part functionality reasons therefore we have been
advised against the"40"mw unit.
