With my older standard-def v1.1 B9 printer, Red resin worked fine and I printed nearly a jug's worth before seeing faint clouding. It was only when testing that printer with the then-new Cherry resin, I needed to crank the layer exposure times to around 14 seconds... that's about the limit for PDMS at that lumen level.

My recent results with the new v1.2 B9 Creator HD:

In addition to the insane detail, the HD projector brings a higher power lamp... this means that each layer's exposure time is only in the 1-2 second range. All the moaning about PDMS clouding is a thing of the past with the new machine. Almost 30 print sessions with a combo of Black and Cherry prints and the PDMS remains crystal clear.
