DEEP's objective has been to create a training model that can bring together professionals from different professional categories, overcoming the current logic that disability is an issue limited to specific sectors. This training model had the following specific objectives: -to develop skills in the field of 3D prototyping; -to bring the social-health world closer to the potential of using 3d prints in the world of disability; -to enable makers to acquire and increase in social-health professionals, the relational and pro-social skills that are fundamental to working with people with disabilities; -to arrive at the description of units of learning outcomes that can be evaluated and, therefore, used in description and evaluation of professional profiles. The direct target group of DEEP was composed of: health professionals, occupational therapists and makers. Only with a change in the logic of taking care of the disabled person, which is no longer only merely "welfare," is it possible to move in the right and authentic direction of social inclusion. Inclusion is effective only with the direct participation of marginalized and discriminated people (Griffo, 2007).
In the current social context of the world's aging population, the number of people with disabilities is set to increase. According to the Survey on Health and Social Inclusion in Europe (Eurostat 2016), there are 70 million people with disabilities over the age of 15. The EU and all its member states are parties to the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD). Within this social framework, a change in logic is essential, one that is no longer merely "welfare", but rather one that is focused on the development of autonomy, social inclusion, and the prevention of forms of marginalization. The DEEP project started from the assumption that in order to cope with such social changes and the resulting challenges, it is crucial to intervene in the training paths of professionals who establish professional relationships with people with disabilities. The technologies currently available can help the rehabilitation, autonomy, school, work and social integration of people with all types of disabilities, ages and pathologies. In the world of 3d printing, the potential emerges especially when people with disabilities themselves are co-designers of their aids.
