One aspect of the present disclosure relates to an apparatus for manufacturing a skin care pack. According to an aspect of the present invention, the apparatus for manufacturing a skin care pack may be provided, the apparatus containing: a housing for providing a working space for forming a skin care pack; a film moving module provided to be movable in one direction within the working space, and having a base on which a film is mounted; a molding machine provided to be movable within the working space in two directions perpendicular to the one direction, and including at least one nozzle module for discharging hydrogel to the base; and a controller for controlling movement of the film moving module and the nozzle module, and controlling discharge of the hydrogel from the molding machine.

A method for producing a polymer latex, includes a step of emulsifying a polymer solution of a synthetic polyisoprene and/or a styrene-isoprene-styrene block copolymer, in water in the presence of a rosin and/or a rosin metal salt, thereby obtaining an emulsified liquid, wherein the rosin and/or the rosin metal salt to be used have/has a total content rate of abietic acid, neoabietic acid and palustric acid, and salts thereof, of 5% by weight or less.

Provided herein are methods, compositions, devices, and systems for the 3D printing of biomedical implants. In particular, methods and systems are provided for 3D printing of biomedical devices (e.g., endovascular stents) using photo-curable biomaterial inks (e.g., or methacrylated poly(diol citrate)).

A composition and method to form a composite core material for use as a panel, molded product, sheet, or reinforcing material. The composition generally includes a microsphere discontinuous portion disposed in a continuous encapsulating portion, such as an encapsulating resin. Final products made with the composition may also comprise a mesh assembly on one or both sides of a sheet or panel, and may comprise a scored panel or sheet such that a plurality of reinforcing blocks or sections are formed which allow the cured product to conform to, and reinforce, irregular shapes and surfaces.

Composite materials with adjustable spectral properties comprised of IR-reflecting micro-domains overlaying an IR-transparent elastomeric matrix, and capable of dynamically controlling IR radiation transmission are described, as well as methods of fabrication thereof. Systems with capabilities to regulate IR radiation (including heat) transmission based thereon, and methods of regulating IR radiation transmission (including thermal regulation) using the same are also provided.

A method and apparatus for forming a sealant coating on a fastener are provided. The apparatus comprises a light generator, a light housing, and a forming cup. The light generator is configured to generate light having a number of characteristics that cures the sealant coating on the fastener. The light housing surrounds the light generator. The forming cup is removably connected to the light housing. The forming cup has an internal cavity with an inner mold line complementary to an outer mold line for the sealant coating.
