摘　　要：综述了近年来基于多种3-D打印工艺的微波直至太赫兹频段无源波导器件的发展研究现状,并介绍了作者所在小组研制的多个基于立体光刻3-D打印工艺的滤波器(包括基于新型高Q值单模和双模球形腔体谐振器的X频段带通滤波器以及基于裂缝波导和紧凑片上结构的W频段带通滤波器).这些滤波器射频性能的测量与仿真结果吻合良好.与相同形状的铜制器件相比,采用非金属材料的3-D打印器件的重量减轻了80%以上,并保持了优良的射频性能.Recent advances on diversified 3-D printed passive waveguide devices operating from micro- wave to terahertz frequencies have been reviewed. Developed by the authors＇group, several waveguide filters fabricated using a stereolithography （SLA）-based 3-D printing technique have been presented. They are two X-band bandpass filters based on novel high-quality-factor single-mode and dual-mode spherical cavity resonators, and two W-band bandpass filters based on a slotted rectangular waveguide and a compact on-plate structure. The presented filters demonstrate good agreement between the meas- ured and simulated RF performances. Compared with their conventional counterparts made from cop- per, these SLA-printed devices exhibit a significant weight reduction over 80% due to the use of non- metallic printing materials, without any penalty of degrading their RF performances.
