Lost‐shell casting as a novel fabrication technique is examined, providing the durability of solid metal components with the shape flexibility of additive manufacturing. The feasibility of lost‐shell casting is established for use in microwave and RF applications. A well known, standard rectangular cavity resonator design was used to validate this novel method of fabrication. Using lost‐shell casting, a cavity resonator with a quality factor of 2200 was constructed. The results shown in this work confirm the validity of lost‐shell casting as a novel method of rapid fabrication for completely metalised components in RF and microwave applications.
