| Abstract Scope |
This presentation covers a model-based approach for toolpath control of Direct Ink Write (DIW) Additive Manufacturing (AM). The model uses the continuity and momentum equations to describe the transient flow of viscous fluid during DIW. The transient flow behavior is found using the Characteristic Method (CM) solver and tested on a flow-controlled Positive Displacement Pump (PDP) DIW system. The two tests performed are system response to the step input and rectangular infill toolpath. Simulations of the PDP LMEX for open-loop and a corrected open-loop control are studied. |
