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
Hi, as far as I can see sprues are in wrong place, for such big rings best is to have one pillar passing trough ring stem and becoming like a tree with at least 5/6 connections to downside of main face. Please browse images here to understand https://www.facebook.com/BlueCast3d/
I’ve tried it with R&R Ultravest and some others. It does the same thing each time… Makes the investment harder and more resistant to resin expansion. It also increases the temp you can go up to before the material starts to break down. Generally I am holding the high temp for 4 to 5 hours depending on what’s in the can. Naturally I’m speaking of FL Castable V2. I would try BlueCast but too many issues with shrinkage.
Hi, your spray solution seems important, i cast some pieces recently, all is globaly ok except some holes as you can see on wolf nose on the link behind… I don’t know much about consequences of waxit on investment but do you think it can fixe this little holes (porosity) pbls ? And when to spray model with ? (before deliver model to caster or it’s better to put it on cast tree, just before going to hoven ?)
Thank you much Chris !
