Hello lab techs, looking for an accurate printer for crown and bridge models , any suggestions?
It's not toxic either. That resin crap is a mess to deal with.Man that printed is locked in materials wise.
Guess that's ok if that's what your looking for.
The filaments were never accurate enough and not specific to dental. This is why the Renfert printer caught my eye.I could be completely off here, so someone please correct me if I'm wrong, but haven't filament printers been widely available the longest? I don't feel like this is where we are going to see the technology advance. I would expect resin printing to become easier and cheaper
Is 50 microns accurate enough for margins ?Yep, I've never seen that style printing done in a way that would work for margins. I can see the appeal of a low impact unit like that for a small lab that needs to be printing models, so I certainly don't dislike the idea. I've worked with Stratosys and Carbon and they both have pretty involved cleanup processes that it would be nice to not have to deal with
I would imagine that it is technically accurate enough. I don't know the number on what is considered to be clinically acceptable, but I also don't tend to use the standard of clinically acceptable, because I think we can do better than that minimum. My comment had less to do with the number given for accuracy and more to do with the way filament prints appear (once again, in my relatively limited experience and of course I have never seen this printer in action) The prints I have seen you can see more "separation" between layers in a sense. for example, if two layers of filament cross a margin you will have slight indention between them that you could feel. They could have figured this out on this printer but I would guess not. Will this compromise the final result? probably not but I wouldn't want to work on models like that.Is 50 microns accurate enough for margins ?
no idea, I've put out some feelers but they don't feel the need to respond to my email.I agree that Renfert makes some great products. I would like to see the prints.
Do you know how much it sells for?
I see your concerns if you are making crowns from the print. However if the accuracy is determined by the scan and mill then it should suffice for the task of checking contacts and occlusion. I'm not a fan of modeless crowns yet I've got the cad down pretty good to get an accurate result.I would imagine that it is technically accurate enough.

Again, this is pure conjecture base on former filament printers, not the one in question. I'll reserve judgement till I see one in person, but this is the type of thing I would not purchase without some hands on experience first
