AB  - Cylindrical microlens arrays (CMLAs) play a key role in many optoelectronic 
      devices, and 100% fill-factor CMLAs also have the advantage of improving the 
      signal-to-noise ratio and avoiding stray-light effects. However, the existing 
      preparation technologies are complicated and costly, which are not suitable for 
      mass production. Herein, we propose a simple, efficient, and low-cost 
      manufacturing method for CMLAs with a high fill-factor via the 
      electric-field-driven (EFD) microscale 3D printing of polydimethylsiloxane 
      (PDMS). By adjusting the printing parameters, the profile and the fill-factor of 
      the CMLAs can be controlled to improve their optical performance. The optical 
      performance test results show that the printed PDMS CMLAs have good 
      image-projecting and light-diffraction properties. Using the two printing modes 
      of this EFD microscale 3D-printing technology, a cylindrical dual-microlens array 
      with a double-focusing function is simply prepared. At the same time, we print a 
      series of specially shaped microlenses, proving the flexible manufacturing 
      capabilities of this technology. The results show that the prepared CMLAs have 
      good morphology and optical properties. The proposed method may provide a viable 
      route for manufacturing large-area CMLAs with 100% fill-factor in a very simple, 
      efficient, and low-cost manner.
