Abstract
From a printing process control standpoint, typically the ink-jet 3D printing process is operated in an open-loop manner, i.e., no sensor measurement is used to create corrective actions during the printing process. As a result, the uncertainties during the printing process can result in undesired part geometry, such as edge shrinking, unreliable dimensions and uneven surfaces. One approach to deal with process uncertainties is through closed-loop feedback control. There are two key components to implement closed-loop feedback control, a control-oriented model and a properly designed feedback control algorithm.
