In university environments, it is increasingly necessary for students to work on different types of competencies that help them to propose novel solutions. This is the context of the present work. The goal is to implement an activity to promote student involvement, while incorporating work on transversal competences and sustainable development objectives. The learning activity has been carried out in the Graphic Techniques in Biomedical Engineering subject. Students have designed, using 3D modeling tools, a game for the cognitive rehabilitation of acquired brain injury patients. Their work was accompanied by a short video showing its operation and a written report. Some works were selected by the students for 3D printing. With the activity, it has been possible to evaluate and work on specific competences of the subject, transversal competences such as design and project and effective communication, as well as SDGs related to health and sustainable production. The students have evaluated the experience and found it positive, both in terms of overall satisfaction and motivation, as well as for allowing them to apply the theoretical knowledge worked on during the subject in a practical context.
