A mould for injection moulding is provided which has a mould body having a plurality of boundary surfaces, the plurality of boundary surfaces having at least one moulding surface configured to delimit a mould cavity. The mould body is made by additive manufacturing. The mould body has a functional domain portion on which the plurality of boundary surfaces and the moulding surface are formed, the functional domain portion being composed of a solid, continuous material structure covering a fraction of the mould body, and an application domain portion which is the complement of the functional domain portion in the mould body, the application domain portion being composed of a three-dimensional material lattice structure having an ordered repetition of unit cells including a periodic minimal surface. The at least one geometrical parameter of the periodic minimal surface is tuned locally to form unit cells with different densities of material.

Described herein is a process for preparing a molded article including at least one structured surface, said process including applying a composition, preferably a foam material, into a mold having at least one structured inner surface and curing said composition to provide the molded structured article. The inner surfaces of the mold can be coated with a coating composition to obtain molded structured articles further including a flexible and durable coating layer. The present invention also relates to a structured molded article, preferably a shoe sole, which is obtained by the process.

An apparatus for the manufacture of an object, the apparatus having a print bed, a stencil, a heater arranged to heat the stencil, and a squeegee. The stencil comprises one or more apertures and is positionable over the print bed. The squeegee is movable to spread a printing material across the stencil and to thereby force printing material through the stencil aperture(s). One or both of the stencil and the print bed is movable to adjust the spacing between the stencil and the print bed.

Disclosed herein are a non-rigid pad for device transfer, which allows uniform contact pressure to be applied between multiple devices and a target substrate to which the devices are to be transferred, a method of manufacturing the same, and a non-rigid pad group for device transfer including the same. The non-rigid pad includes: a base plate; and multiple pillars each protruding from one surface of the base plate with one end thereof connected to the one surface of the base plate, the pillars being bent and deformed upon application of external force, wherein the non-rigid pad is disposed between a transfer film to which multiple devices to be transferred to a target substrate are adhesively attached and a pressing unit providing pressing force to transfer the multiple devices to the target substrate, the non-rigid pad being bent and deformed upon application of pressing force by the pressing unit to allow uniform contact pressure to be applied between the multiple devices and the target substrate.

This method for manufacturing a light absorber includes: a first step for irradiating a resin substrate with ion beams; a second step for etching the irradiated resin substrate with an alkaline solution to form an uneven surface on the surface thereof; a third step for forming a transfer body which covers the uneven surface of the etched resin substrate; and a fourth step for peeling off the transfer body from the resin substrate to obtain a light absorber. A metal film, a photocurable resin, and a silicone rubber are disclosed as an example of the transfer body.

A plasma etching method using a Faraday cage, which effectively produces a blazed grating pattern.

A mold cavity which is a mold die includes a die body and a plating layer provided on the surface of a mold surface. In this case, the mold surface has a leather-grain transfer surface for forming a grain pattern. The leather-grain transfer surface includes a first uneven-shape part and a second uneven-shape part formed at the surface of the first uneven-shape part and smaller in an uneven-shape width than the first uneven-shape part. The uneven-shape width falls within a range of 10 μm or more and less than 500 μm. The plating layer is an electroless-plating layer. A thickness of at least part of the plating layer falls within a range of 0.1 μm or more and less than 10 μm.

A method for manufacturing a cured product pattern of a curable composition includes the steps of, in sequence, depositing a droplet of the curable composition onto a substrate; bringing a mold having an uneven pattern formed in a surface thereof into contact with the curable composition; curing the curable composition; and releasing a cured product of the curable composition from the mold. The mold has a recess having a bottom surface and a stair structure arranged to form an opening surface that becomes wider from the bottom surface toward the surface of the mold. In the contact step, the curable composition comes into contact with the stair portion after a top of the droplet comes into contact with the bottom surface.

An imprint mold having a synthetic quartz glass substrate having a transfer fine pattern formed on a surface thereof; and a coating layer formed on at least a part of the fine pattern by at least one of materials different from the substrate.

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, then mixing the 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.
