Implementations of an artificial nail measurement system and method (“artificial nail measurement”) are provided. In some implementations, the artificial nail measurement may comprise a mold casting kit. In some implementations, the artificial nail measurement may further comprise a mold extraction kit.

In some implementations, a method for the artificial nail measurement comprises a user receiving and using a mold casting kit to form a mold of the user's fingernails, shipping the mold to a nail technician to form a cast or replica of the user's fingernails, and the nail technician using the cast to measure the user's fingernails to select from pre-made artificial nails that then designed and shipped to the user for use.

A method of fabricating a casting, the method including applying a substrate to a sacrificial mold, the sacrificial mold including a shaped non-planar receiving surface to receive the substrate and provide a casting of the substrate having a shaped structure corresponding to the receiving surface; and subjecting the sacrificial mold and casting to freeze drying conditions and sublimating the sacrificial mold from the casting to form a cast article including the shaped non-planar structure.

A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

A method of manufacturing a microstructure comprises printing a positive mold structure, filling the positive mold structure with a second material to form an elastically deformable negative mold structure, filling the negative mold structure with a third material to form the microstructure, and releasing the microstructure from the negative mold structure. Advantageously, the negative mold structure can be stretched to facilitate the release of the microstructure. For example, the microstructure comprises a chamber with capped micropillars for the generation and/or analysis of muscle tissue.

A mold for casting a micro-scale dry adhesive structure includes an upper surface including a first cavity having a first depth, a negative pattern for an array of micro-scale structures defined in a surface of the first cavity, and at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures, the at least one second cavity defining a negative pattern for a standoff of the micro-scale dry adhesive structure.

Provided are a transdermal absorption sheet capable of achieving control of the dissolution rate and suppression of diffusion of a drug, and a method of producing the same. A transdermal absorption sheet includes a sheet portion, and a plurality of needle-like protruding portions formed by a plurality of frustum portions arranged on the sheet portion and needle portions arranged on the frustum portions, in which at least one of the needle-like protruding portions has a cavity portion extending from the sheet portion to the frustum portion.

A method of manufacturing marine riser buoyancy elements includes providing a master mold and mold inserts such that a range of buoyancy elements may be manufactured from one master mold and providing the mold inserts such that an annular space between the riser main conduit and the buoyancy elements, or a groove width between the buoyancy elements may be varied during manufacture.

A vehicle display device decorative part and a vehicle display device include a first area provided in the vehicle display device that displays information regarding a vehicle, and having a first pattern formed of a plurality of first grooves, and a second area provided to be included in the first area, and having a second pattern formed of a plurality of second grooves. As a result, the vehicle display device decorative part and the vehicle display device exhibits an effect to realize new and fresh visual effects due to a synergistic effect by a combination of the first pattern formed in the first area and the second pattern formed in the second area included in the first area.

A method employs a first polymeric material to deposit first and second pattern layers laterally shifted from each other such that laterally shifted pattern layers form between them an empty volume with a variable cross-section that varies along with the first and second pattern layers. A second polymeric material is cast in the empty volume between the first and second pattern layers to cast a complex-shaped 3D object identical in shape to the empty volume between the first and second pattern layers. Radiation is applied to cure the first and second polymeric materials. The first polymeric material is a water breakable material composition including acrylamide, methacrylamide, acrylate, acrylic acids, and acrylic acid salts, hydroxy(meth)acrylate, carboxy(meth)acrylate, acrylonitrile, carbohydrate monomers, methacrylate and polyfunctional acrylics.

A macromolecule forming mold, which is integrally formed by a polymer body. Multiple communicated runners are formed inside the polymer body; a material injection port is penetrated in the surface of the polymer body, and the material injection port is communicated with the runners, so that a thermosetting castable fills the runners by means of the material injection port and is cured and molded, and the polymer body is damaged to take out a thermosetting elastomer. A thermosetting elastomer and a manufacturing method therefor. The thermosetting elastomer has the characteristics such as excellent physical properties and lightweight properties.
