Publication number: 20220024206Abstract: Aerosol jet printing is a popular digital fabrication method for flexible and hybrid electronics, but it lacks sophisticated process control architectures that would enable more widespread adoption in manufacturing environments. An optical measurement system can be used to track the aerosol density upstream of the printhead. For example, the measured optical extinction combined with the aerosol flow rate, is directly related to deposition rate and accurately predicts functional properties, for example electrical resistance. This real-time system offers a compelling solution for process drift and batch-to-batch variability, a valuable tool for more fundamental studies of the process science, and a viable technology to support real-time control of aerosol jet printing.Type: ApplicationFiled: July 22, 2020Publication date: January 27, 2022Inventors: Ethan Benjamin Secor, Adam Wade Cook, Bryan James Kaehr, Rebecca Rosa Tafoya
