Abstract. Additive technologies have long been used in various industries, including radio engineering. The use of various 3D printers can significantly speed up the process of prototyping and small-batch production. This paper proposes a process for manufacturing waveguide paths by the laser growth method, as well as highlights their post-processing and application features.

Keywords: waveguides, radio engineering, manufacturing, 3D printer
