Latest Patents

One of Edwards' key patents is titled "Flow rate control in extrusion deposition process." This patent focuses on achieving closed-loop control of flow rate during the additive manufacturing of solid objects. By utilizing a distance measuring tool to scan the surface of a previously deposited layer, the system compares the scanned data to a desired target value. A control algorithm, which may be a proportional-integral control algorithm, calculates a corrected second flow rate for subsequent layer deposition. This method allows for precise adjustments, especially in cases where the solid object shape results in multiple isolated regions.
