Ive done about 10 units so far, they worked out well.. not sure if the SLM is for me or not.. is too granular for my liking.. I think I will try the print/cast once I figure out what alloy I want to use. The fits were about 95% dead on. One margin was lifted but luckily I could cut it back for a porc margin that the dr ordered anyway. Other than that great fits..
biggest problem was bubbling of the opaque down to the metal. i cut the bubbles off, filled them in with opaque and fired it with porcelain and they fired out fine, didnt blow up.. but that makes me nervous.
