wait a second, we are talking here...printing 3D the actual ventilator machine and then try to replace the high precisions instruments, it's not the right principle! If you renew and restart from the beggining you might hv a chance to cross trought the last generation of ventilators, but if you stuck on the basic of these one...you are not finding high precision to be massive product. Either you build a new concept..or you try Chemestry, basis.

can you print this...1st in plastic, and 2nd the robot frame in large scale?
