The ability to customize your model is great for any type of doctor (surgeon, orthopedic surgeon etc.) who needs access to specific information about their patients' anatomy or medical history in order to make an informed decision during surgery. I do not like having to pay extra money per print just because you want more detailed features/information than what's included by default. It would be nice if there was some way we could get our own custom files without paying additional fees but this isn't possible at the moment so it doesn’t really matter much since all of my prints come from existing files anyway. We are able to use these models as reference tools while performing surgeries which has helped us immensely when preparing complex cases such as those involving congenital heart defects where multiple procedures may need to occur over time.
