Here's a lost wax casting test of a Form 1, clear resin print. This time I tried casting a gold crown (45% gold, 6% palladium, 39.5% silver) from a Form 1 print of a CAD tooth. Investing protocol and procedures were the same as my original post, except for using a lower burnout temp of 1152 degrees F, and casting with a gold alloy instead of pressing with lithium disilicate glass.
The results were as good as when I use wax to build a crown. There does not appear to be any problem with clean burnout of the clear resin using Microstar HS investment at the two temps I've tested so far. Surface texture of the casting is good, but the surface of the printed crown is a bit rough (printed at .05mm). Because there is finishing of the metal involved anyway, this isn't really a big problem. Any areas of the print that are too rough can be very quickly smotthed with a thin coating of wax.
Please keep in mind that the resin produces a lot of black smoke during burnout and a vent hood is necessary so you don't breathe the fumes.
Hopefully this is helpful information.
