It's nominally an open-format printer, but we had nothing but problems trying to run non-Straumann resins on it, and their tech support wouldn't talk to us unless we were working with their products. Worked fine with their resins, very smooth workflow with the RFID-chipped bottles and so on, but we got very few successful prints with third-party resins. Sorry about having to deal with Straumann at all, we've basically blacklisted them for providing support for equipment we use, if we're using something under their aegis we'll assume we'll have to service it ourselves (which means we just stay away where possible).
