Stereolithographic 3D Printing of Post Filters with Non-Conventional Geometry

Additive Manufacturing (AM) technology is becoming very popular for many applications, including the manufacturing of electromagnetic components. Several scientific papers have been written on this topic, but most of them are focused on the manufacturing of classical structures. In this paper instead, it is shown how the versatility of AM can be used to design new components with non-conventional geometry. This is shown through the design of filters with resonant posts having non-conventional shape and position exploited to obtain higher performances. The manufacturing of such structures would have been very hard with classical manufacturing technologies. The feasibility with AM stereolithographic (SLA) technology is demonstrated through measured prototypes.
