Honestly it’s a cool idea to have a portable printer though, and it could be achieved but just differently.

Like what if you just took the basic design of a normal 3d printer, but made it snap apart and back together, and then made those pieces fit into the briefcase?

You’d just need two vertical pillars, one horizontal rod. Then the print bed itself could move in either the x or y dimentions since the print head would be stationary in one direction.

Hope that makes sense but in my head this solution is way more practical even if you needed to do a calibration after each setup.
