Abstract Scope |
Aerosol jet printing (AJP) is a novel additive manufacturing technology that uses a series of gas flows to deposit an aerosolized ink onto a substrate, fabricating micron-scale circuits. To scale up AJP for manufacturing, repeatability of AJP process parameters must be evaluated during long print sessions, often referred to as drift in process parameters, and across separate print sessions. In this study, two types of print sessions were conducted: multi-hour print sessions to evaluate drift and several print sessions of five replicates to evaluate repeatability across separate sessions. The consistency of prints was evaluated based on their conformity to the intended geometry and electrical conductance. Changes in the visual quality and conductance were compared to the print time or print day to determine how long the printer produced consistent products. This work will help to inform scheduling of future print sessions in which circuit consistency is necessary. |
