The MachinE Tool ALliance for Skills (METALS) intended first to map out and identify skills needs in the European machine tool sector, studying which technology areas would become more prominent and where more competences would be needed. Second, it aimed at preparing online learning materials in line with the emerging technologies identified.To this extent, in the initial phase of the project, the consortium conducted surveys, interviews with experts and desk research and concluded that additive manufacturing is a technology area that would prominently impact on the skill set of the European machine tool workforce between 2015 and 2025. On the basis of these findings, the consortium then prepared a European machine tool skills panorama concretely presenting skills needs in key areas of the advanced manufacturing process (such as design, operation and maintenance) within this time span This panorama paved the ground for the development of a curriculum on additive manufacturing at EQF level 5, whose final version included 27 learning units (26 in the English version) divided along three main knowledge areas: work process-oriented area, additive manufacturing-specific area and entrepreneurship-oriented area. Based on this curriculum, METALS partners prepared e-learning materials meant to address the current and future skills gaps in the European machine tool industry, particularly in relation to additive manufacturing technologies. These learning materials were prepared with significant focus on clearly defined learning outcomes and made freely available in English, Italian, German and Spanish in the project e-learning platform (https://metals.mobil-lernen.com/en/elearning). The array of project results has been endorsed by a variety of leading actors in this community, including additive manufacturing machine producers and universities.
