ALEXANDRIA, Va., June 4 -- United States Patent no. 12,318,840, issued on June 3, was assigned to Xerox Corp. (Norwalk, Conn.).

"Surrogate modeling of molten droplet coalescence in additive manufacturing" was invented by Soren Taverniers (Palo Alto, Calif.), Morad Behandish (San Mateo, Calif.) and Svyatoslav Korneev (San Jose, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques for modeling a droplet-based additive manufacturing process are disclosed. An example method includes obtaining training data, setting one or more hyperparameter values in a data-driven surrogate model architecture, and training, by a processing device, the surrogate model architecture on the training data to generate a t...
