Scanning mirrors can deflect, reflect, and pattern the laser beam. Traditional laser galvanometers rely on deflection motors and mirrors, which are bulky and costly. Micro‐electro‐mechanical systems (MEMS) micromirrors have small size and high integration, but they require long preparation cycles and sophisticated equipment and expensive materials. Polymer scanners prepared by 3D printing technology have the advantages of low cost and rapid preparation, but their reliability needs further study. In this study, a single‐axis electromagnetic scanner was proposed and tested for reliability. The mechanical structure of the scanning mirror is prepared by fused deposition modeling (FDM) using acrylonitrile butadiene styrene (ABS) as material, the radial magnetic field is provided by neodymium magnet set, and laser patterned copper foil serves as the drive coil. The prepared scanner achieved an optical scan angle of 45.2° at a resonant state of 276 Hz. The effect of temperature and humidity on the device reliability is investigated experimentally. Temperature has a significant influence on the resonance frequency and scanning angle of ABS‐based scanner. In addition, the change of relative humidity has less effect on the scanner. The five scanners tested were still working properly after 240 h (more than 2 × 108 cycles) of testing without failures and less than 1.5% frequency drift has been observed.

“…Additive manufacturing rapid prototyping technology, also known as 3D printing technology, has also been playing an important role in state-of-the-art 3D fabrication processes because of its fast prototyping capability and low manufacturing costs, with various dielectric and conductor materials available for use in 3D printing processes. Among the various additive manufacturing techniques, fused deposition modeling (FDM), digital light processing (DLP) and polymer jetting (PolyJet) are most often used for fabricating millimeter-wave and THz components such as antennas [29]- [31], waveguides [32], [33], and THz sensors [34], [35]. However, due to its capability in fabricating high-resolution 3D structures and various choices of printing materials, the DLP technique is often preferred to FDM and PolyJet fabrication.…”

220-320 GHz Hemispherical Lens Antennas Using Digital Light Processed Photopolymers

et al. 2019

This paper presents a 220-320-GHz hemispherical lens antenna fabricated using photopolymer-based additive manufacture and directly fed by the standard WR-3 rectangular waveguide without any additional waveguide extension. The microfabrication process is based on digital light processing rapid prototyping using the Monocure 3DR3582C resin-based photocurable polymer. This gives various key advantages, including ease of antenna fabrication, manufacturing speed, and cost-effectiveness due to its rapid fabrication capability. Even though the photopolymer is found to have a loss tangent of 0.034 at 320 GHz, the all-polymer lens antennas still achieve a fractional bandwidth of 37%, covering the whole 220-320-GHz WR-3 waveguide band with a measured gain of approximately 16 dBi at 0 • over the whole band. A measured return loss of better than 14 dB is achieved from 220 to 320 GHz with a half-power beamwidth of approximately 12 • , which is relatively constant over the whole WR-3 band.
