A template manufacturing method includes preparing a structure including a first substrate and a stacked body that is provided on the first substrate, the stacked body including a first lower layer including a first material, a first upper layer provided on the first lower layer including a second material different from the first material, and a first cover layer provided on a first cover region of the first upper layer and including a third material different from the second material. The method further includes forming a first resist layer on a portion of the first cover layer and on a first portion of the first upper layer, and exposing a second portion of the upper layer. The method yet further includes removing the second portion of the first upper layer using the first cover layer and the first resist layer as a mask.

This disclosure concerns a master model for the production of a mold, comprising: (a) a first part, a second part comprising a textured surface; wherein the first part and the second part are connected.

The invention relates to a method for coding a dimensionally stable packaging container or an associated component made of a plastics-based and/or paper-based material composition, the packaging container being suitable for storing consumer goods such as food, washing agents, etc., wherein, during a shape-forming process for forming the three-dimensional packaging container or the associated component by means of a shaping tool mold, at least one outer and/or inner side undergoes, in at least one position, a shape-changing treatment acting on its first surface in order to produce at least one three-dimensional code.

The present disclosure relates to an aerosol production assembly. The aerosol production assembly may include a reservoir that contains an aerosol precursor composition and an atomizer that receives the aerosol precursor composition from the reservoir and heats the aerosol precursor composition to produce an aerosol. The aerosol production assembly may additionally include a body that directs the aerosol through an outlet. The body may include a surface including a micro-pattern that defines at least one of hydrophobic and anti-microbial properties. The surface including the micro-pattern may not include a chemical coating that provides these properties. Rather, the surface may define a three-dimensional structure that provides hydrophobic and/or anti-microbial properties. A related assembly method is also provided.

According to one embodiment, a mixture includes a fluoropolymer monomer having at least one functional group amenable to polymerization, a pore-forming material, and a polymerization initiator. According to another embodiment, a product includes a porous three-dimensional structure comprising a crosslinked fluoropolymer, where at least 20% of a volume measured within an outer periphery of the porous three-dimensional structure corresponds to the pores.

A molded resin product includes a plurality of protrusions formed in a predetermined region. A histogram indicating a height distribution of the plurality of protrusions has two peaks having a boundary height as a boundary therebetween. In a case where protrusions having height equal to or smaller than the height Hx are first protrusions and protrusions having height larger than the boundary height are second protrusions among the plurality of protrusions, an arithmetic mean curvature of the first protrusions is smaller than an arithmetic mean curvature of the second protrusions.

An iridescent vehicle badge (and methods for making it) that includes a translucent, polymeric badge having a non-planar shape and comprising an interior and an exterior surface. Further, at least one of the surfaces of the badge comprises a plurality of diffraction gratings that are integral with the badge, each having a thickness from 250 nm to 1000 nm and a varying period from 50 nm to 5 microns. In some cases, the thickness can range from 500 nm to 750 nm. The period, in some cases, can vary within a set of discrete values in one or more portions of the at least one of the surfaces of the badge, e.g., from 150 nm to 400 nm.

The object of the present invention consists of a device that allows for the easy creation of 2-dimantional and 3-dimensional plastic objects using a 3-D drawing pen. The device object of the present invention is comprised of a flexible, heat resistant, non-sticky, transparent silicon mat characterized by the presence of grooves cut in its surface, the path of which can be of any geometric or non-geometric shape. The groove works as a guide for the 3-D drawing pen user by allowing such user to stretch the melted plastic, extruded by the 3D pen, on its bed, and within its walls, so that once hard the plastic object is exactly of the shape of the groove and its path, and not an imprecise shape caused by the unstableness of the hand of the free-hand 3-D pen user.

A preparation method of a bionic adhesive material with a tip-expanded microstructural array includes the following steps: machining through-holes on a metal sheet; modifying morphology of a through-hole by electroplating, using the metal sheet in step 1 as an electroplating cathode, and arranging the electroplating cathode and an electroplating anode in parallel to prepare a hyperboloid-like through-hole array assembly, fitting a lower surface of the hyperboloid-like through-hole array assembly tightly to an upper surface of a substrate assembly to prepare a through-hole assembly of a mold; and filling the mold assembly with a polymer, curing, and demolding to obtain the adhesive material with the tip-expanded microstructural array.

The invention relates to a method for creating a surface structure on a mold, wherein first structural elements are created using a laser structuring process in a first step, and second structural elements, which are smaller than the first structural elements, are created using an anodic oxidation process in another step following the laser structuring process. The invention further relates to a mold of said type and finally to a plastic film or a plastic component having a surface structure as well as to a method for the production thereof.
