3D System spec sheet for the SLA350 states that 5000 hours with min 160mw at
VAT is the guarantee life it looks as though our last 500 hours are going to
remain at approx 135mw .

3D did a laser tweak at 4700 hours and raised it up to 227mw but the next
nine builds were

227 215 221 187 212 215 218 206 203

before dropping down to 138mw.

has any other SLA350 solid state users experienced similar disappointment
and asked for compensation ?
