Metal 3D printing, specifically XL Metal 3D Printing, also known as Wire Arc Additive Manufacturing (WAAM), is an emerging technology that has the potential to revolutionise the way we design and form metal structures. WAAM uses a robotic arm to deposit molten metal layer-by-layer, enabling the formation of complex geometries and customised designs that would be impossible with traditional manufacturing methods. The technology enables designers to create complex metal structures rapidly and efficiently, reducing material waste and decreasing the time and cost of construction. WAAM can create building facades, stairs, and other structural elements with complex shapes and geometries. 

The research agenda has the potential to streamline the manufacturing process, enabling designers to create functional prototypes and end-use parts with high levels of accuracy and repeatability. This is particularly useful in aerospace, automotive and architecture industries, where precision and performance are critical. WAAM technology also enables designers to amalgamate structures and integrate functional features. It can push the boundaries of what is possible in terms of form, function, aesthetics, and form with synthetically accomplished designs. 

This research agenda was initiated through the support of the IMCRC as part of the IMCRC Design Robotics project.
