Compositeas has achieved several notable R&D developments using 3D printing with carbon fiber. These include a suspension arm made of carbon fiber and polyamide, aircraft wing pieces (TIP) or a coupling between train wagons. The ground covered indicates that the potential of this technology is enormous and that its implementation in large-scale productions is a matter of time. Among other advances, it makes unnecessary the use of printing molds, allows to create complex designs that would be impossible with the usual manufacturing processes and reduces the use of material to the strictly necessary. This opens the way to jobs that can be done in small factories, involving the customer in the design and the whole process, doing it more participatory.
