Criticism and Proposal of a Model for the Design and Rapid Set-Up of a Training Course Based on 3D Printing

The spread of additive manufacturing and the adoption of 3D printers have generated a sudden adaptation of teaching methodologies in education. In the manufacturing sphere, 3D printing has called for innovation in the criteria and systems required to transmit skills in Science, Technology, Engineering and Mathematics (STEM). In this innovative context, the lack of teaching guidelines and the evident presence of certain criticalities in training activities in the field of 3D printing are highlighted. In this research project, the most widespread criticalities are identified and a matryoshka model with a holistic view of the entire ecosystem of educational activities in the field of additive manufacturing is proposed. Such a model allows for an immediate identification and subsequent assignment of criticalities to each of the process steps and consequent opportunity for resolution, allowing for an ex-ante design or resetting of the course in an exemplified and flexible form.
