    Abstract: A method includes obtaining a composition (1016) disposed on a surface of a substrate (1010), irradiating a first portion (1017a) of the composition for a first irradiation dosage, and irradiating a second portion (1017b) of the composition for a second irradiation dosage. The composition (1016) includes fluoropolymer particles and a binder material that is polymerizable upon exposure to radiation. The first portion (1017a) and the second portion (1017b) are adjacent to or overlapping with each other, and the first irradiation dosage and second irradiation dosage are different. Irradiating the first and second portions of the composition (1016) polymerizes the binder material and forms a three-dimensional article (1017) having a first portion (1017a) and a second portion (1017b) on the surface of the substrate (1010). The first portion (1017a) and second portion (1017b) of the three-dimensional article have different thicknesses in an axis normal to the surface of the substrate (1010). Three-dimensional articles are also described. The article (1017) can be. for example, a structured film.

    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.

    Abstract: A continuous method of manufacturing adhesives is provided. The method includes obtaining an actinic radiation-polymerizable adhesive precursor composition disposed on a major surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes moving the actinic radiation-transparent substrate and irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. Optionally, the method also includes irradiating a third portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate prior to moving the substrate. The first irradiation dosage and the third irradiation dosage are often not the same, thereby forming an integral adhesive having a variable thickness in an axis normal to the actinic radiation-transparent substrate.

    Abstract: A method of making an adhesive is provided, including obtaining an actinic radiation-polymerizable adhesive precursor composition disposed against a surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. The first portion and the second portion are adjacent to or overlapping with each other and the first irradiation dosage and the second irradiation dosage are not the same. The method forms an integral adhesive having a variable thickness in an axis normal to the surface of the actinic radiation-transparent substrate. Also, an adhesive article is provided, including a substrate having a major surface and an integral adhesive disposed on the major surface of the substrate. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is provided, including a display that displays a 3D model of an article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an article.

The liquid medium includes a polymerizable compound, a secondary component, and a multiphoton absorber. An article is also provided. The article includes a material defining one or more tortuous or arcuate channels, one or more internal architectural voids, one or more undercuts, one or more perforations, or combinations thereof, at least one of which exhibits a surface roughness of 1.0 micrometer Ra or less.
