    Assuming every hinge there is motorized, that’s 6 servos. That looks like a nightmare to calibrate, which it will need to do a lot of if it’s shoved in some backpack for travel on a routine basis.

    And the print head looks like a bitch to take apart to service if you get a jam.

      Yeah this thing would suffer really hard from over time degradation and you would have no way to fix it probably. Its like the Iphone of 3D printers. The beauty of 3D printers is exactly that everything is exposed and can be easily modified, repaired or replaced.

      Not to mention the vibration of the head caused from a single mount point. The engineerinh to keep anything close to the 0.2mm resolution common on non mobile printers. Will be expensive.

      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.

      If you add position sensors to the servos you shouldn’t need much calibration after the first go, no?
