Design of microwave waveguide devices for space and ground application implemented by additive manufacturing

摘要: This paper presents the application of low cost additive manufacturing technique named fused filament fabrication (FFF) to implement waveguide devices. In addition reduced price, it also has added benefit rapid prototyping, allowing designer modify geometry swiftly. Otherwise this kind manufacture opens way experiment with shapes until now unachievable by traditional subtractive techniques. order demonstrate its feasibility, experimental results three filters low-pass, high-pass, and band-pass responses respectively, designed in Ku band usual specifications satellite communication systems have been designed, printed, metallized measured. conclusion, advantages limitations are highlighted, special attention dedicated metallization process, since is bottleneck process.
