I don’t think anyone ever replied to this one…
I haven’t used the low-shrinkage yet, but the beauty of BlueCast is not having to cure. They list specifics of washing the prints under running IPA, but I just wash as usual in my Formlabs wash station and it works fine. I dry them, then invest. I’m actually guilty of using my hair dryer to speed things up, but if I have time I let them air dry. I live in a humid climate, so air dry sometimes takes awhile.
I have not used BlueCast in other cartridges. I filter it back into the BlueCast bottle if I’m not printing within a day or two. Castable resins are VERY caustic and will cause your tray to degrade more quickly. I recommend not leaving any castable resin on the printer. I have had a tray fail on my printer…printer was okay, but cleanup was not fun!
I use a baby bottle warmer to warm the BlueCast resin before printing. Since I always filter the resin back into the bottle, I take the 1/2 liter bottle and put it in a Philips Avent bottle warmer, which has a setting that is the same as the recommended temperature for BlueCast. Then pour it into the tray.
I have not heard of anyone doing the cast-in-place stones in resin, with the thought being that the temperature for burnout is much higher than the lower temperature used for cast-in-place. I found this discussion on the B9 site. https://www.b9c.com/forum/viewtopic.php?t=1985
