Additive manufacturing technology has received much attention with impressive demonstrations ranging from musical instruments, to vehicles, to housing components or even entire buildings. Different structural materials including metal, polymer, ceramics, biological tissues and even concrete, have been incorporated in various 3D printing technologies. Printing dimension ranging from nanometers to meters has been reported. This presentation will highlight several research projects in the area of 3D printed components and potential systems for GHz to THz operation. Two printing techniques, polymer jetting based on photosensitive polymer and fused deposition modeling using thermal plastics will be discussed. A number of demonstrated examples including electromagnetic crystals, waveguides, antennas, phased array, gradient index lenses and holographic devices will be presented. Interesting applications of these 3D printed structures such as a new type of lens array for electronic beam scanning will also be described. Some of the important future research directions and challenges including potential novel designs enabled by 3D printing technology, development of additive manufacturing compatible materials with desired electromagnetic properties, and simultaneous printing of high quality conductor with other non-conductor materials will be discussed as well.
