    Abstract: The present disclosure provides a printable composition. The printable composition includes a polymer, a polymerizable component, a temporary solvent, a photoinitiator, and optionally an inhibitor. The present disclosure also provides an article including an integral blend of a thermoset polymer and a second polymer different from the thermoset polymer. Further, the present disclosure provides a method of making an article. The method includes (i) providing a printable composition; (ii) selectively curing the printable composition to form a gelled article; and (iii) removing at least a portion of the temporary solvent from the gelled article. The method may optionally include (iv) curing unpolymerized polymerizable component remaining before or after step (iii). Also, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a plurality of layers of an article, the article including: an integral blend of 8 to 50 wt. %, inclusive, of a thermoset polymer and 30 to 90 wt. %, inclusive, of a second polymer different from the thermoset polymer, wherein the weight percent is based on the total weight of the 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.

    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: The present disclosure provides a multiphoton imaging method. The method includes a) immersing a semi-submersible microscope objective in a liquid medium that is at least one of scattering or absorbing; b) directing laser light through the semi-submersible microscope objective and into the liquid medium in an image-wise manner under conditions such that multiphoton absorption by the multiphoton absorber occurs, and at least partial polymerization of the polymerizable compound occurs resulting in an article; and c) removing uncured polymerizable compound to clean the 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.
