Abstract Scope |
Aerosol jet printing (AJP) is a versatile additive manufacturing technology for flexible and hybrid electronics, offering precise feature dimensions and intricate structures under various functional inks. However, maintaining constant line width over time remains challenging due to variations in process parameters such as aerosol density and process disturbances. This work presents the development of a digital twin that coordinates the in-situ print quality monitoring and control of part line width based on a neural state space model (NSSM) and model predictive control (MPC). The process involves identifying critical control parameters for line width deviation, analyzing the printed part's image, quantifying line width, training NSSM over these parameters, and providing feedback on the AJP setup with the help of a controller to control line width according to quality requirements. Besides ink jet printing, the developed approach provides guidelines for a multivariate control approach for other additive manufacturing processes. |
