Happy to comment on any Carbon questions out there. I recently took delivery of our 2nd Carbon. After years of running 6 other printers we moved to Carbon. Yes the price is crazy, you never own it, they do not cut any deals and you most likely will not hit the ROI you want. What it does, it works hands down and that was the solution we were looking for. Is it $50k worth it, not so much if you are only producing models. Dentures, night guards, custom trays, surgical guides you have to feed the beast to make it worth while. You don't have to babysit it, worry about bad print or worry about any validation issues. Again not for everyone and it took me months to pull the trigger on one. I will say if you get one, get one with the large build plate. The smaller build plate (same plate just the computer chokes down the printable area) is a huge disappointment. DO NOT GET A CARBON IF YOU ARE GETTING THE SMALL BUILD PLATE it is absolutely useless. It is a joke of a build plate unless you get the large build plate. This was a major sticking point with us. Go all in or get something else. The Carbon Dentsply Lucitone material is great, no issues. Use stock card teeth or mill your own teeth, no problem. Again happy to tell the good and bad if interested.
The Keystone night guard material for Carbon is great. Perfect fit and often the case can be completed from an IOS without a model. Material is clear and we are seeing excellent results.
