With a total of 2 patents, his work focuses on enhancing the efficiency and precision of 3D printing technologies.

Latest Patents

One of McKiel's latest patents is titled "Flow rate control in extrusion deposition process." This invention addresses the need for closed-loop control of flow rates 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 layers. This innovation allows for more accurate and consistent layer deposition, even in cases where the object shape results in multiple isolated regions.

Another significant patent is the "Method and apparatus for transposing extruded materials to fabricate an object surface." This invention describes a mechanism that transposes the paths of multiple extrusion nozzles to create a solid object. By paralleling the surface contour of the object, the paths of the extruded traces are directed in a complementary manner. This allows for the first extrusion trace to define the object surface while a second trace is deposited behind it. The ability to cross the paths of the extruded traces enables the integration of fine graphic features into the object's surface, especially when different colors or visual appearances are used.
