Bob,
can i ask what scanner was used for that crown?
So Bob , would you recomend the Roland as a first mill for a lab , instead of Origin 500 ? In order to achieve the result you have shown us , do you need special custom made milling strategies , or an average user with no milling experience can do this as well ? Thank you .
P.S. Love your anatomy library !
From Roland's web-site.....
".....Positioning accuracy +/-0.004"/12"(+/-0.1mm/300mm), under no-load conditions
Repeat accuracy +/-0.0019"(+/-0.05mm),under no-load conditions +/-0.0008"(+/-0.02mm),under no-load conditions
Origin reproducibility (when the power is switched on/off) +/-0.0019" (+/-0.05mm) +/-0.0008" (+/-0.02m) ...."
Bob, you are so in the dark about what you are stating.
Impossible to even be close to accurate to 50uM.
The run-out alone of the spindle is enough to go outside of the tolerance of Dentistry, then add in the above slop!
Hi,*
I have never worked with the Origin 500 so I really can't provide a viable comparative analysis. However, I do know the guys at Origin and like them a lot. *They can usually customize milling strategies for you depending on what your needs are, so I'd recommend asking them.
We have created our own milling strategies with the Sum3D CAM that we use for our Roland mills. We are a Sum 3D reseller. *We would definitely provide the mill strategy for the restoration shown to any new (or past) SUM 3D customer of ours. I would recommend the Roland for a first mill if your intention is to fill it with zirconia, wax and PMMA. However, if you want to mill metals you should look elsewhere. *The Roland is very easy to use and will produce restorations like the photo i posted in this thread. There is no magic to it, no genius CAM person required. *If you (or someone in your lab can do CAD) the CAM and mill part will be simple. Obviously, *to get results like the pics posted your design would require similar detail.

Bob, have you tried milling wax or PMMA with your tooth library and the smaller bur? If so, how did it come out? Good occlusal detail at a 1:1 ratio?
Crown looks great by the way

Sorry Scott, their stuff fits much better than your crap, and it does not look muddy. Your printing sucks also.
Yes, we are now milling (on a Roland) all wax in my lab. Here are some results. The E-tech printer has become a dust collector.Bob, have you tried milling wax or PMMA with your tooth library and the smaller bur? If so, how did it come out? Good occlusal detail at a 1:1 ratio?
