That certainly is the way of some of the locked down printers, but the Pegasus uses ordinary pour-from-the-bottle goop, but it has to be theirs. Some nonsense about voiding warranty, terminating support, but that's senseless. I've not spent the bucks for the broad spectrum resin option and don't know the back-door secrets involved. My Pegasus remains in the box it arrived in from the Kickstarter years ago. A shame really.
