A method for manufacturing a soft stamp includes providing a substrate having a first electrode and a second electrode, the second electrode being formed at a distance less than 100 nm from the first electrode so that a nanogap Ng is formed between the first and second electrodes; pouring a curable substance over the first and second electrodes and into the nanogap Ng; curing the curable substance to form a soft stamp; and removing the soft stamp from the first and second electrodes. The soft stamp has a nano-feature having a size less than 100 nm.

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.

The present disclosure relates to a method of designing a spherical microstructure mold (604-614) module to be incorporated into a calendering roller (600) for generating a microstructure (108) on a planar surface (104), comprising calculating a first curvature (204) on a cross-sectional planar surface (202) for a first microstructure point of the spherical microstructure mold module, calculating a second curvature (210) of a spherical surface (102) of the spherical microstructure mold module, measuring a radius (214) of the spherical surface (102), the radius (214) being from the center of the spherical surface (102) to the first microstructure point, and determining a location of the microstructure (108) on the planar surface (104), the location being derived from the first curvature (204), the second curvature (210), and the radius (214).

Provided are a method for producing a tire vulcanization mold and a maintenance method. A positioning member protrudes at a position corresponding to a position on a master mold surface. A positioning hole is formed by a tip end of the positioning member in a rubber mold to which the surface of the master mold is transferred. The tip end is embedded in the positioning hole so that a rear end protrudes from the surface of the rubber mold. The rear end is embedded in a plaster mold to which the surface of the rubber mold is transferred. A case is detachably fixed to the tip end protruding from the surface of the plaster mold. The case is cast into a mold to which the surface of the plaster mold is transferred and fixed. A valve body is inserted into the case from which the positioning member is removed.

Provided is a roll mold that has a plurality of linear grooves arranged side by side on its outer peripheral surface and in which an optical step between adjacent linear grooves is sufficiently small. A roll mold comprising, on an outer peripheral surface thereof, n linear grooves extending in a roll axial direction or a direction inclined with respect to the roll axial direction and arranged side by side, where n is 800 or more, wherein the n linear grooves are arranged in a manner that a gradual decrease and a gradual increase in groove depth are repeated, and the number of points at which a transition from the decrease to the increase in groove depth occurs is m or less, where m is selected from 2 to 8.

The disclosed computer-implemented method may include creating a computer-generated model for a haptic feedback system including a plurality of actuators arranged in a first layer of the haptic feedback system, and a plurality of channels routed in a second layer of the haptic feedback system, the second layer being below the first layer, printing a three-dimensional wax mold structure of the computer-generated model, and forming the haptic feedback system in a single step using the three-dimensional wax mold structure. Various other methods, systems, and computer-readable media are also disclosed.

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 method of producing a substrate with a fine uneven pattern is a method of producing a substrate having a fine uneven pattern on a surface thereof, the method including a step (a) of preparing a laminate provided with a substrate and a first resin layer provided on the substrate and having a first fine uneven pattern formed on a surface thereof; and a step (b) of forming a second fine uneven pattern corresponding to the first fine uneven pattern on the surface of the substrate by etching the surface of the first fine uneven pattern using the first resin layer as a mask, in which the first resin layer is formed of a resin composition (P) including a fluorine-containing cyclic olefin polymer (A) or a cured product of the resin composition (P).

An implant shredder includes a base and a cutting member. The base includes a first chamber and a second chamber intercommunicating with the first chamber. The first chamber includes an inlet. The second chamber includes an outlet. The cutting member is received in the second chamber. The cutting member is driven by a driving member to rotate. The cutting member includes a plurality of cutting edges located on a circumference of a same radius. The plurality of cutting edges is rotatably disposed adjacent to a location intercommunicating with the first chamber. An implant forming method includes creating data of an outline of an implant; producing a shaping mold based on the data; and cutting a to-be-processed object with the implant shredder, mixing the cut to-be-proceed object with a biological tissue glue to obtain a raw material, and filling the raw material into the shaping mold to form the implant.
