A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

A method for producing a thermally conductive sheet S includes a step of obtaining a thermally conductive composition by mixing a reactive liquid resin, which forms a rubbery or gelatinous matrix when crosslinked, a volatile liquid having a boiling point 10° C. or more higher than a curing temperature of the reactive liquid resin, and a thermally conductive filler; a step of forming a molded body by crosslinking and curing the reactive liquid resin at a temperature 10° C. or more lower than the boiling point of the volatile liquid; and a step of evaporating the volatile liquid by heating the molded body, in which these steps are performed sequentially.

A fiberglass reinforced aerogel composite may include coarse glass fibers, glass microfibers, aerogel particles, and a binder. The coarse glass fibers may have an average fiber diameter between about 8 μm and about 20 μm. The glass microfibers may have an average fiber diameter between about 0.5 μm and about 3 μm. The glass microfibers may be homogenously dispersed within the coarse glass fibers. The aerogel particles may be homogenously dispersed within the coarse glass fibers and the glass microfibers. The fiberglass reinforced aerogel composite may include between about 50 wt. % and about 75 wt. % of the aerogel particles. The binder bonds the coarse glass fibers, the glass microfibers, and the aerogel particles together.

The present invention relates to 3-D structures having high temperature stability and improved micro-porosity as well as processes of making and using same. The disclosed 3-D are advantageous because they have low densities and low permittivities. When compared to previous 3-D structures, the present structures maintain their low permittivities over a broader range of electromagnetic frequencies. Thus, when used in communication devices such as array antennas, can provided higher communication performance in high temperature environments.

The present disclosure relates to compositions and methods for three-dimensional printing.

The present invention provides a method for preparing a microgroove array surface with a nearly cylindrical surface based on an air molding method, and relates to the technical field of functional surface preparation. The method includes the following steps: (1) preparing a microgroove array surface, uniformly spreading a layer of a liquid polymer film to be formed on the auxiliary plate, and placing a spacer block in an empty position on the microgroove array surface; (2) placing the auxiliary plate spread with the liquid polymer film on the spacer block on the microgroove array surface, maintaining this state, and feeding the auxiliary plate into a vacuum drying oven; and (3), setting a pressure in the vacuum drying oven according to a designed pressure, heating and solidifying the liquid polymer film, and separating the microgroove array surface to obtain the microgroove array surface with the nearly cylindrical surface.

A method of making a three-dimensional object by additive manufacturing from a blended resin including (i) at least one light polymerizable first component and, (ii) at least one, or a plurality of, second solidifiable components that are different from said first component, the method including: providing a first resin and a second resin, where the resins produce three-dimensional objects having different mechanical properties from one another when all are produced under the same process conditions; mixing the first and second resins with one another to produce the blended resin, the blended resin producing a three-dimensional object having mechanical properties intermediate between that of objects produced by the first and second resins when all are produced under the same process conditions; and dispensing the blended resin to the build region of an additive manufacturing apparatus; and then optionally but preferably producing a three-dimensional object from the blended resin in the apparatus.

The invention relates to a method for the additive manufacturing of a silicone elastomer article. In particular, the invention relates to a method for the additive manufacturing of a silicone elastomer article and a support using a 3D printer.

A mechanical system that assembles or deploys pre-stressed structures. The assembly or deployment process outputs and elastically deforms material to form flexural members having a sinusoidal shape and stored potential energy. The sinusoidal shaped members are oriented and deployed with support members as they take shape. Sinusoidal shaped members are formed from a series of contiguous flexures; each flexure's properties may be engineered using a simulation technique. Each flexure is formed from a region of a sinusoidal member's length that begins and ends at antinodes. During assembly or deployment support members are positioned at antinodes maintaining the flexures' shapes and the assembly's pre-stressed state. By controlling the forces applied to and position of each flexure formed during assembly, the distribution of potential energy within the assembly and its secondary shape can be engineered. Elastic potential energy may be harvested from the material forming the flexural members.

A patient interface device for use in ophthalmic surgery, which includes a rigid body and a suction ring joined to a lower end of the body, where the suction ring includes an annular skirt made of a soft and flexible material and located at a lower end of the suction ring, and where an inner surface, and optionally an outer surface, of the skirt is coated with medication. The medication includes one or more of the following types of medication: anti-inflammatory, antibiotic, numbing, lubricating, and anti-redness. The coating method may include dip coating, sputter deposition, ultrasonic-spraying, and spin-coating. The skirt may be formed by a process that increases its material porosity and/or surface roughness, and may be surface-treated to enhance adhesion and retention of the medication.
