Much better detail... But it harder for the customer to see details
What is your curing process ?

Detail prints as well as emerald?
Just purchased a b9 about a month ago. We fully explained the use of the machine was to be for jewelry design and casting. We were also told that the resins will work with regular investment with out additional steps. The distributor sent us the emerald green resin. Really great detail but we are now experiencing bad castings. We cure for 9.5 minutes in the curing unit that came with the b9. We have previously cast( with good results) b9 resin samples from the b9 distributor using regular investment and our standard burnout. One of our first prints after setting the machine up (a small canoe paddle) very simple design cast great with 2.5 minutes curing and about 3 to 5 days on the shelf before investment and cast. Every thing in the process is the same. The only thing that has been variable is the shelf time of the models ( samples from the distributor, and our own paddle design) There is no way of knowing the exact curing process used for the samples that we received. Our curing process was controlled and went from 2.5 minutes on the canoe paddle ( good casting) to 9.5 minutes curing. The first cast was cured at 2.5 minutes with now time on the shelf came out bad very rough surface. Second one cured 9.5 minutes again no shelf time came out the same "bad" the 3rd was cured again for the 9.5 minutes and failed as the others. I am seeing others on the forums that are experiencing the same issues. I have attached some images of some of our fails.
Is the yellow resin a b9 product ? What investment are you using ? I have heard of a 3rd party yellow resin. If this yellow resin is the best for regular investment ie: R&R ultra vest / Kerr sating cast and not offered by b9 where do i get some ?
