I sent a few cases to them yesterday. They came back designed, which is what I asked for, but the designs are completely useless. Waxed crowns dont fit the die, which I dont understand, why would they remove something from the die? Ive been designing for 8 years and Ive never had anything fit like that off the mill. The wax crowns were so high in occlusion that it wouldve been faster to do them myself, and in fact I might have to. Im afraid to mill out the zirconia..
One problem is they only send the final .stl file, not the whole design file so you have to explain to them what changes to make.. completely defeating the point of having someone else do it. I cant imagine that labs send out crowns like this..
