A Multi-Inlet Extrusion System for Closed-Loop Spatial Profile Control in Large-Format Additive Manufacturing

Rectangular nozzles are attractive for large-format additive manufacturing (LFAM) due to their improved deposition efficiency. However, single-inlet feeding of high-aspect-ratio nozzles inherently induces lateral pressure gradients, causing center-heavy flow and eliminating localized control during …
