The paper is aimed to study the profile evolution of microlens fabrication in short duration from several mini-seconds to seconds. Droplet deposition method, similar as inkjet-like printing, could be applied for the 3D lens-making process, in which optical liquid material was used here. The transient mechanism of lens-forming behavior is fully understood by using numerical simulation of fluid thermodynamics. Deposition results can be shown that concave and convex profiles are determined by a couple of physical parameters, such as solid content percentage and evaporation rate. With the experiments, it is expected that the rapid method can be further implemented in many manufacturing of small objects in the future.

  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
