Printing a duplex stainless steel dragon

Most 3D printed objects are less than 30 cm long. So, how is the 10 m long Oregon Dragon Bench possible? Instead of using powder, the bench was built layer by layer applying a robotic welding technology called "WAAM". Made with 2209 duplex stainless steel weld wire, the Oregon Dragon Bench exemplifies how 3D printed metal structures can do more with less.
