I was absolutely mesmerised by this process when I first saw it. The machine shown in this video is a Nissin 3D CNC Tube Bender. You can see the machine bend tube in any direction to form complex 3D forms. It is even possible to bend continuously variable curvatures.
Imagine the design optimisation that is possible with such a flexible machine. In my head I am dreaming up wild space frame dune buggies with minimal frame welding. What would you design and make with this process?
