I have a B9 Creator v1.1 but updated to a v1.2.
I also modified the projector to allow better UV pass-through and less heat to degrade the sylgard. This worked magically and has allowed me to print much faster. I did this with Mike Joyce's input.
I have been a faithful B9 contributor early on but have been a bit quieter in the last few years.
I have three vats. Two are aluminum KAT VAts. Which I love. The other is a clear acrylic vat. Both need recoating.
I also have an unopened bottle of Cherry resin.
The B9 is a great machine, however, I mostly print larger things and do not need one that prints so small anymore.
I am asking $1200 plus shipping but I would be willing to negotiate with the right person.
Let me know if you are interested or if you have any more questions.
