Abstract

Aerosol Jet Printing (AJP) is an emerging direct-write technology for fabricating high-resolution functional materials. Despite its advantages, the absence of robust process control remains a major barrier to widespread industrial adoption. This paper addresses the challenge of implementing closed-loop control in AJP by presenting an approach based on laser transmission measurements. Building on previous research employing camera and optical scattering-based feedback mechanisms, this work presents a control architecture that enables real-time, accurate, and non-intrusive monitoring of the aerosol stream. Expanding upon foundational studies, this method facilitates localized process control by employing a single beam splitter with dual photodetectors for measurement and reference signals. This work reviews the current state of AJP process monitoring, identifies limitations of existing control solutions, and details a scalable architecture designed to enhance precision and adaptability in future implementations.
