| Abstract Scope |
We undertook to use LPBF 3-D printing of pure Niobium to produce 3-D resonators. The use of 3D printing enabled quick prototyping, design flexibility, and scalability, both in terms of size and in terms of multiple unit arrays. An LPBF Mlab system by Concept Laser was used to print a cavity design for 6 GHz with a high q-factor. Printing parameters, build plate, supports, and part orientation were optimized, with 100 W at 1200 mm/s, providing the best part density. The cavities were successfully produced along with witness samples for metallurgical analysis. Electrolytic polishing of the printed parts was explored and all results on printing, characterization, and polishing will be presented. |
