there is no reason why they can't make a printer that works with their proprietary resins and everyone elses resins. this whole "locking" the printer to be specific to a certain resin is crap. seeing how well and consistent the Asiga printers have been, I wished I'd have shopped more. I still havent gotten the "training" that uncle henry is supposed to provide, and that we paid for, with the printer. luckily I know my way around a printer and have been using it successfully for awhile now.
As great as the EOne is, the support behind it, especially from EnvisionTec themselves is lackluster. having to call and get put on a "wait list" for a return call for something as simple as a file to be able to print with the new resin you just bought is frustrating. or when you buy a resin that says its compatible with your printer, spend $300+ on the resin, call to get the right RFID card for the printer to register it, to find out when you're trying to get the file for the nesting software that the resin you bought and already loaded into the printer does not work with the printer and they don't have a "buildstyle" for the EOne and you're SOL.
I've learned a lot of expensive lessons this year while working on updating our lab to a more efficient, modern workflow. the printer being one of them.
