They don't quite support the same filament. The DaVinci printers have proprietary filament cartridges with an identification chip that you either have to disable somehow or be forced to use DaVinci brand filament. I personally don't feel that it affects the printer's capabilities one way or another, but getting a model that uses chipped print material just feels like encouraging bad behavior.

As far as I know, the Solidoodle doesn't do that. (but I've not really paid enough attention to them I must admit.)
