Abstract
Methods of manufacturing fuel injector nozzle structures such as, e.g., nozzle plates, valve guides, combinations of nozzle plates and valve guides, etc., as well as other articles incorporating microstructured features. The methods may employ multiphoton processes to form microstructured patterns on a three-dimensional structured surface to provide nozzle structures and other articles that include finished microstructured features such as, e.g., through-holes extending from one or more cavities, where at least a portion of the three-dimensional structured surface is used to form the cavities. Forming a microstructured pattern on a three-dimensional structured surface can reduce the time needed to form nozzle structures that include microstructured features and other nozzle structure features (e.g., cavities) by avoiding the need to form the other nozzle structure features using the multiphoton processes.
