I have checked the cosmo post, thanks for the reply, i guess there are some limitations with this systeme... I will call ivoclar to get some more info.
I waxed a few post and cores and than scanned them into my system. Sent them off and had them milled out of Zr. The problem is the sprue attachments. It's hard to get them finished down good before sintering I guess. I had to do a lot of adjustment when I got the posts back. Looked good afterwards though.
