A pattern is formed on a substrate with forming a layer of a curable composition (A1) containing a polymerizable compound (a1) on a surface of the substrate, then dispensing droplets of a curable composition (A2) containing a polymerizable compound (a2) dropwise discretely onto the curable composition (A1) layer, subsequently sandwiching a mixture layer of the curable composition (A1) and the curable composition (A2) between a mold and the substrate, then irradiating the mixture layer with light to cure the mixture layer, and releasing the mold from the mixture layer after the curing. The curable composition (A1) except a solvent has a viscosity at 25° C. of 40 mPa.Math.s or more and less than 500 mPa.Math.s. The curable composition (A2) except a solvent has a viscosity at 25° C. of 1 mPa.Math.s or more and less than 40 mPa.Math.s.

Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

A multi-chemistry structure includes: a plurality of interconnected polymer struts arranged in a lattice; a first layer of the lattice including a first array of first unit cells; a second layer of the lattice including a second array of second unit cells; at least one region of the lattice being formed of a first polymer; and at least one region of the lattice being formed of a second polymer different from the first polymer.

Systems and methods for shaping a film. Formable material in an imprint field on the substrate may be contacted with a shaping surface of a template. Outer boundaries of the imprint field correspond to outer boundaries of the shaping surface. Shaping the film includes forming a cured layer within the imprint field while the shaping surface is in contact with the formable material. Shaping the film may include separating the shaping surface from the cured layer. Shaping the film may include moving the template away from the imprint field to a first offset location wherein the outer boundaries of the shaping surface are offset relative to the outer boundaries of the imprint field. Shaping the film may include curing a second portion of the formable material while the template is at the first offset location so as to form the shaped film.

Systems and methods wherein one or more processing operations on an identification document occur after a radiation curable material is applied to a surface of the identification document but before the radiation curable material is fully cured. The one or more processing operations can occur before any curing of the radiation curable material takes place. Alternatively, the one or more processing operations can occur after the radiation curable material has been partially cured, and before the radiation curable material is fully or completely cured.

There is provided a 3D printing system, methods, and materials for the 3D printing of objects that include a cured hydrogel material, an uncured hydrogel material, and a support material. The cured hydrogel material may define a scaffold for organs or other biological structures. The 3D printing system selectively deposits the hydrogel material and support material, dries the hydrogel material, and selectively applies a catalyst to the hydrogel material to selectively cure the hydrogel material. Once the 3D printing has completed, the uncured hydrogel material may be drained and the support material may be melted or dissolved leaving a scaffold of cured hydrogel material that may be infused with living cells of the desired organ or biological structure.

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.

One embodiment is a method that includes generating drop pattern information. The method may comprise receiving pattern information. The pattern information may include one or both of: a substrate pattern of a representative substrate; and a template pattern of a representative template. The method may further comprise receiving offset information about a particular substrate that is representative of a measured state of the particular substrate relative to a reference state. The drop pattern information may represent a plurality of positions to place droplets of formable material on the particular substrate. The method may further comprise outputting the drop pattern information that is representative of the formable material that fills a volume between the template and the particular substrate that is in the measured state and the formable material does not spread into a border region at an edge of the particular substrate.

The present invention relates to processes for selective reshaping of nanoparticles in three dimensional articles, three dimensional articles produced by such processes, and methods of using such three dimensional articles. As a result of the aforementioned process, such three dimensional articles can have selective tuning that arises, at least in part, from the reshaped nanoparticles found in such articles. Such tuning provides the aforementioned articles with superior performance that can be advantageous in the areas including such as optical filters, multi-functional composites and sensing elements.

The present disclosure is directed to additive manufacturing cartridges having an oxygen impermeable layer and to processes for producing cured polymeric products by additive manufacturing wherein the oxygen content during additive manufacturing is limited such as by use of the cartridge and/or by use of an inert gas.
