I am a post graduate person from IIT having
specialisation in CAD and RP.
I have some issues regarding SLA / Viper system.I
would like to get the clarification from all of you on
these issues.The issues are following:
1. Laser Optics replacement: 3D systems gives the
warranty of 7500 hrs for their laser optics.After that
the whole laer optics need to be changed which costs
around $50,000.This is pretty costly affair to change
whole laser optics.Recently 3D systems claim that
there is no need to change the whole laser optics, but
it can be repaired in parts.IS THIS TRUE?
2. Laser Age: As laser gets old the speed gets
reduced.That means the speed of laser is inversaly
proportonal to the life of laser.As its get older,
speed reduces.IS THIS TRUE and what is this factor of
proportionality.By what percetage it gets reduced?
3. Resin Contamination: After 30-40 runs the whole wat
of resin needs to be replaced due to contamination.It
cause a great loss of material.IS THIS TRUE?
These issues are very crucial while deciding on the
SLA / Viper for business plan since it reflects
greatly on the costing. Hence i would like your
clarification on these issues.
I would particularly appreciate comments and
clarification from SLA / Viper users and 3D Systems'
experts on these issues.
