The present invention relates to a preparation method for a microneedle patch. Specifically, the present invention provides a preparation method for a microneedle patch, and the method comprises steps: (1) milling a base into a master mold of the microneedle patch; (2) conducting surface treatment on the master mold, to obtain the treated master mold; (3) conducting reverse molding on a surface of the treated master mold, conducting deaeration, curing, and demolding, to obtain the cured daughter mold; and (4) casting the modification solution on the surface of the daughter mold, and then conducting deaeration, drying and curing, to obtain the microneedle patch. The method for preparing the microneedle patch in the present invention can greatly reduce the milling difficulty, and save the milling cost and time. The microneedle molds with different aspect ratios, areas and shapes can also be prepared as required, following with reverse molding to diverse microneedle patches. Therefore, a feasible implementation scheme is provided in present invention for the production application of the microneedles and the feasibility of the wide application is greatly enhanced.

A method for producing a bespoke grip accessory for a handheld apparatus. In one embodiment, the method comprises determining a person who will be gripping the handheld apparatus, encasing a replica of a gripping surface of the handheld apparatus in a conformable mold, obtaining an imprint of a grip profile of the person in the conformable mold encasing the replica gripping surface, hardening the mold comprising the imprint of the grip profile into a hardened mold, scanning the hardened mold to obtain a data file comprising a three-dimensional representation of the grip profile imprinted in the hardened mold, converting the data file to a format suitable for fabricating a grip accessory fitting both the gripping surface and the imprint of the grip profile, and fabricating a bespoke grip accessory based on the converted data file, wherein the fabricating comprises a process further comprising additive manufacturing.

An artificial nipple is formed of an elastomeric polymer by use of 3D printing after imaging of a mother's breast in an active state of lactation. The artificial nipple used as an attachment to a baby bottle or as the nipple component of a pacifier. Use of an artificial nipple formed in this manner mitigates a problem with nipple confusion, as may otherwise manifest in newborn offspring.

A functional polymeric cutting edge structure and methods for manufacturing cutting edge structures using polymeric materials are provided. A razor blade for use in a razor cartridge or a blade box for assembly in a razor cartridge frame may be formed using the present invention.

The present invention includes producing a preliminary mold (10-1 or 20-1) provided with two-dimensional patterns (111 or 211) having a shape of a microneedle array (30) therein; producing microneedle array molds (10 and 10-2 or 20 and 20-2) having a three-dimensional shape by expanding air inside the patterns (111 or 211) having a two-dimensional shape to deform the patterns (111 or 211) having the two-dimensional shape into molds having the three-dimensional shape; and after pouring a biodegradable resin into the microneedle array molds (10 and 10-2 or 20 and 20-2) and solidifying the biodegradable resin, completing the microneedle array (30) by removing the microneedle array molds (10 and 10-2 or 20 and 20-2), thereby providing a mold for production of a microneedle array and a production method of the microneedle array using the same capable of tightly suturing an affected area without inducing pain.

A method of deposition is disclosed. The method can include dispensing a formable material over a substrate, where the substrate includes a non-uniform surface topography, and where the substrate includes an active zone and an exclusion zone. The method can also include curing the formable material in the exclusion zone to form a circular edge between the exclusion zone and the active zone, contacting the formable material with a superstrate, and curing the formable material in the active zone to form a layer over the substrate, wherein curing is performed while the superstrate is contacting the formable material.

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 production method of a mold having a recessed pattern includes: a plate precursor preparation step of preparing a plate precursor having a pedestal on which a protruding pattern is disposed; a resin plate preparation step of preparing a thermoplastic resin plate having a recessed step portion; and a resin plate precursor production step of producing a thermoplastic resin plate precursor, the resin plate precursor production step including a positioning step of positioning the protruding pattern of the plate precursor and a center position of the recessed step portion, and a recessed pattern forming step of forming a recessed pattern having an inverted shape of the protruding pattern on the thermoplastic resin plate by pressing the protruding pattern of the heated plate precursor and the pedestal against the recessed step portion, thereafter cooling the plate precursor, and separating the plate precursor from the thermoplastic resin plate.

Disclosed is a method for producing a mold obtained by providing a monolithic optical lens element having at least a finished optical surface, the monolithic optical lens element being made of an organic material. The method includes: coating the finished optical surface with an electrically conductive material; depositing on the coated finished optical surface a layer of metal to produce a metal element having a surface which is a replication of the finished optical surface; and separating the monolithic optical lens element and the metal element, the metal element forming a mold replicating the finished optical surface of the monolithic optical lens element.

According to an embodiment of the present invention, a method for producing a duplicate of a nano-pattern texture of a surface of an object through electroforming using an imprint mold comprises selecting the object having the nano-pattern texture, disposing the selected object and pretreating a surface of the object by washing, drying and then forming a nano-thin film thereto to block transfer of impurities, metallizing a surface of the plastic mold through, e.g., vapor deposition, spraying, and wet silver mirror reaction, and performing a first electroforming of the surface of the plastic mold, and repeating to thus manufacture a plurality of metal module master molds.
