Ok this is carried over from another thread, to recap.. this is first milled titanium coping i received back:
great result huh! and i cherry picked the die to have a lovely smooth margin to make it as easy as possible for their mills.
their DMLS copings were just as bad. They are now milling NP but i really dont see the point in wasting any more time.
In answer to previous questions:
yep this was scanned and designed by me.
and yep that is the die it was scanned from. It was made with fuji rock optiscan so no powder or anything was used. The scanner was calibrated only a couple of days ago (gets done once per week now)
I have made no modification to it.
The best bit is the email i got back from their HQ after sending these photos:
"I would like to inform you, that the pictures that you sent yesterday, are enough to exclude a defect in the material.
We assume that in the edit of preparation margin it was a mistake.
Please check your restauration again!
Thank you for your understanding.
Best regards!"
Here is the margin in software from the same area shown above:
This is as clear is it gets for this scanner, You see anything wrong with that?
NOw this is the same kinda response i get from this company with every fit issue (and there are ALOT of them). Blame the user.
Now they have the same file, they can see them selves how clear the margins are, What a joke!.
Maybe someone can post some images of some unadjusted milled NP/Titanium copings they are getting from another supplier to restore my faith that all this cad/cam milling actually does work!.
Now i had exactly the same kinda of fit with a DMLS coping i tried with them, fit on die was horrid. Now the interesting thing is they made another coping for me and printed an SLA die from the same data and guess what, the coping fit the SLA die spot on.
So what does this tell us, its the junk scann data, duh!
No one there will admit that there is an issue with the scanner.
EDIT1: Just checked the technical manuals for this companies scanners. There is NO published data for accuracy and when i asked via email, the rep did not have that information.
EVERY other major scanner manufacturer appears to publish accuracy data. What is this company trying to hide??
