This document is the second deliverable of task T3.4. “Set of exercises with 3D printing”. The aim of this report is to provide a progressive immersion in additive manufacturing technology. The reader will acquire the necessary knowledge about what this technology is and how it works, the main applications within the furniture and wood sector, and the benefits of its use in education. In addition, the 3D printing exercises (definitions and .stl files) developed in this work package are included. We believe that this material will bring added value to those schools and teachers who want to get started in this field.
