Dear List,

We have an SLA-190 with a vat full of old SL 5170. It is still working but
the material properties are not the same anymore and a skin is formed on the
surface of the vat during a build. Is there any way that you can recondition
the resin? Or is it just to empty the vat and send it for disposal? Any
ideas would be highly appreciated. Anybody have some SL5170 that they need
to get rid off???
