Carried out by the Institute of Steel Construction and Mechanics of Materials at Technische Universität (Technical University) Darmstadt, the project involved using arc welding to melt a metal wire and build it up layer by layer.
Students erected a three metres long by 1.5 metres wide steel bridge running over water on the university grounds and tested an alternative method for bridge construction.
Messer supported this project with its welding gas mixture Ferroline and its experience in this area.
“In contrast to conventional manufacturing, 3D printing offers advantages in the production of complex components,” Messer explained in a press release.
“The layer-by-layer construction makes it possible to produce complex structures that are difficult or impossible to achieve with conventional production methods.”
“Often 3D printing is used for the production of single pieces or small series, because the construction of a conventional production is too expensive.”
“Examples include hip prostheses and dentures in the field of medicine as well as turbine blades and turbochargers.”
