We first designed and manufactured a bended WR5 waveguide in order to assess achievable roughness and insertion loss. In a second step, an existing 240 GHz choke horn antenna design, previously manufactured using metal coated Stereo Lithography Apparatus (SLA) and Selective Laser Melting (SLM) technologies, has been prototyped using MLS. Measured performances of the MLS antenna prototype have been benchmarked with SLA and DMLS ones. Achieved performances are promising since without any post processing MLS compete up to 325 GHz with metal coated SLA technology while it enables a metallic part manufactured in a single piece.Show less >
