Machinery : Additive Manufacturing : 3D Printer
MX3D is the company that revealed the potential of robotic wire arc additive manufacturing (WAAM) to the industry. We have made 3D metal printing more flexible, faster and cheaper. By launching the first dedicated robotic WAAM software in 2019, we enabled companies, engineers and designers to print end-to-end large-scale 3D metal objects in-house. Now, MX3D is ready to transform industries further by introducing its turnkey M1 Metal AM System.

3D Printing A Bridge With A Twin
The world’s first 3D-printed steel bridge showcases technology that could reduce the amount of material used in structures. It has a network of sensors that continuously feed data into a ‘digital twin’; that will monitor how the bridge behaves over time and help refine the design of similar structures in future. Hugh Ferguson reports and looks at how a similar approach to monitoring is being adopted across civil engineering projects.
The origins of this bridge lie within a small creative design studio in Amsterdam, Joris Laarman Lab, headed by designer and artist Joris Laarman. In about 2014, excited by opportunities presented by emerging technologies, the team decided to develop designs in 3D-printed stainless steel. This presented an immediate challenge: no-one had before produced large steel objects using 3D printing or additive manufacturing. The process requires molten metal to be deposited in multiple layers. At the time, there were already tools for metal inert gas (MIG) welding. In this arc welding process, a continuous solid wire – usually 1.2 millimetre in diameter – is electrically heated and fed from a welding gun. There were also robots on which the tools could be mounted. However, no-one had used robots with MIG welding. Robots were generally used for repetitive ‘pick and place’ tasks, rather than complex welding control.
Robotic 3D manufacturing providing greater flexibility
Robots are extending their reach. These multiaxis articulators are taking 3D manufacturing and fabrication to new heights, new part designs, greater complexity and production efficiencies. Integrated with systems to extend their reach even further, their flexibility is unmatched. Robots are virtually defying gravity in additive manufacturing (AM), tackle complex geometries in cutting, and collaborate with humans to improve efficiencies in composite layup. This is the future of 3D.
3D printing is already a multibillion-dollar industry, with much of the activity focused on building prototypes or small parts made from plastics and polymers. For metal parts, one additive process garnering lots of attention is robotic wire arc additive manufacturing (WAAM).
