I think if you search this site you’ll find that others have had the gassing problem with SLM.

Yes I had the same issue. When I called the company they told me a different way to treat it than regular cast. From the degas temp to a different wash technique for the opaque.

Are you using a bonder, like ceram bond from bredent(there are other brands available)? I've been using slm for a couple of years now, never had any cracks or bubbles.
