Wireless chargers for electric vehicles and mobile devices have become attractive for researchers all over the world. This is because wireless chargers totally abolish the hassle of long charging cables. For example, a parking lot with individual wireless chargers implemented at each parking spot is sought to be more sustainable than its counterpart that has wired chargers with long thick cables scattered all over the place. This increased sustainability comes at the cost of a higher safety and health risk associated with the leakage of electromagnetic fields from wireless chargers. Thus, high efficiency electromagnetic shields and guiding structures have become of great importance. There are few recently developed ideas about how to build underground wireless chargers with fairly good shielding characteristics. In this workshop, these ideas are going to be presented in details. Additive manufacturing techniques used to build such electromagnetic structures are the main focus of this workshop. An ultraviolet 3D printer with liquid resin as the printing material is used in this workshop. The workshop is based on a hands-on approach to give the audience a practical experience with sustainable low-cost manufacturing techniques of complex electric conducting systems
