From the video: the biggest advantage of using a 6 axis robotic arm is that the nozzle can be pointed in any orientation. This allows you to design and print along 3d curves which make stronger parts. Traditional 3d printers stack 2d planes on top of each other, which make for strong layers but weak layer-to-layer connections. This is OK for some parts but not all. Another downside is things like holes - vertical holes can be pretty accurate and strong, but horizontal holes are not (since the curve is made by different layers). I wonder if this could be simplified to have a traditional 3 axis gantry style 3d printer with a nozzle which could rotate on one or two axes? It wouldn't have the full range of motion that a robotic arm does, but it might be "good enough"? A Bowden drive could help reduce the mass of the extruder making it a little more feasible.
