MX3D is a revolutionary digital fabrication process. Developed by Joris Laarman Lab, MX3D uses industrial robots and an advanced welding machine to print metal structures in mid-air. It originated from the Lab’s desire to 3D print large-scale functional objects—until MX3D the size of 3D-printed parts had been limited to the size of the printer. This new technology advances the technical and aesthetic possibilities of digital fabrication. Parametric modeling software generates self-supporting, attenuated forms. The Dragon Bench is the first series created using the MX3D metal printer. In 2018, the MX3D Bridge—the world’s first fully functional footbridge 3D-printed in stainless steel—will be installed over a canal in Amsterdam.
