[Gru]

I'm confused. What are you milling with "stone pucks"?

 

[Sevan P]

Models........ duh. No seriously.

quick solid model for a case done modeless. in know it sounds redundant, but humor me.

 

[grantoz]

Why not print one? Tying up a mill for a verification model doesn't seem logical. We had the same idea but we decided to have them printed from Argen. Turn around in 3days, cause argen takes two, in before the cut off on Monday model back in office on Wednesday. Crown milled while waiting. For single units I tell the docs, slight adjustment maybe needed on the contacts, occ is .3 out and they drop in.

Take a PMMA disk and duplicate it, then poor stone into it and boom.

Or even try to make a solid out of pmma.

You know pouring a stone to a PMMA dupe is not a solid model...

I've done it for exactly that purpose. Messy, hard on burs but you can do it.

To create a stone disk, not a solid model. Then you can mill the disk, but finding the right stone to do it with is the question.

I thought you said mill a PMMA crown then pour a solid around it.

We milled a couple contact models on DWX50s, poured stone into disc shape and went with Zirconia settings. Turned out ok, but slow.

Been a while, but ETI empire or ETI Digital sell gypsum disks, WHY didn't I think of this earlier. Talked with Steve from ETI at lab day west and this thread popped in my head. They cut a small opposing, solid and die out of the DWX-4 mill in 45 min, looked pretty clean.
