Abstract: The present disclosure provides a method of making an additive manufactured article. The method includes: a) attaching a multilayer structure (300, 500) to a build platform (210); b) selectively curing a photocurable composition (219) that is in contact with a porous layer (330, 530) of the multilayer structure, thereby forming an object attached to the porous layer; and c) separating the object from the build platform. The multilayer structure includes an adhesive layer (310, 510), an impermeable layer (320, 520) attached to the adhesive layer, and a porous layer (330, 530) attached to the impermeable layer. The adhesive layer of the multilayer structure is attached to the build platform. The present disclosure also provides an object made by the method, and the multilayer article used in the method. Use of the multilayer article assists in improving adhesion between the build platform and the object.

Abstract: Described herein is a curable composition comprising an amorphous fluoropolymer having an iodine, bromine and/or nitrile cure site; a peroxide cure system comprising a peroxide and a Type II coagent; and a photoinitiator, wherein the curable composition is substantially free of a binder material. Also described herein, are methods of curing the curable composition using actinic radiation and articles thereof.

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.
