A step-and-repeat imprinting mold is provided that is capable of restraining deformation of an end of a convex and concave pattern formed in a cured resin layer when the mold is removed. According to embodiments of the present invention, a step-and-repeat imprinting mold includes: a transparent base; a transparent resin layer formed thereon and having a pattern region formed with a convex and concave pattern; and a light shielding member provided between the transparent base and the transparent resin layer so as to overlap the pattern region in part of the pattern region.

The invention is characterized by a semifinished composite structure product with the at least two layers, of which the at least one layer, in which the continuous fibers are contained, is heated such that the matrix of thermoplastic material is heated within at least one first surface region to or above a melting temperature that can be assigned to the thermoplastic material, and the matrix of thermoplastic material is kept to a temperature below the melting temperature within a second surface region directly adjoining the first surface region. The semifinished composite structure product is heated in this way so that the moldable thermoplastic, continuous fiber-reinforced composite structure in which the continuous fibers within the first surface region are movable relative to each other and those within the second surface region are spatially fixed relative to each other.

To provide a method for manufacturing a double-sided adhesive material suitable for the size and shape of various articles using a simple process without reducing the yield of the adhesive material that is used, and to provide an article with a double-sided adhesive material that uses the double-sided adhesive material obtained by this manufacturing method. [Resolution means] Liquid photo curing adhesive 12 is applied by direct drawing onto a specific region corresponding to the size and shape of an article to be used, on the surface of a first plate 10, using a robot. A sheet shaped second plate 20 is placed on the first plate 10 where the adhesive 12 was applied, such that the adhesive 12 is interposed between both plates. Light for curing the adhesive is then irradiated from both sides of the adhesive 12 so that the light will pass through both the first plate 10 and the second plate 20 and reach the adhesive 12.

A system and method for 3D microfabrication projects light capable of initiating photopolymerization toward a spatial light modulator that modulates light responsive to digital masks corresponding to layers of the structure. Projection optics focus the modulated light onto an optical plane within a photopolymerizable material supported on a stage. A computer controller causes the spatial light modulator to project a sequence of images corresponding to the digital masks while coordinating movement of the stage to move a position of the optical plane within the photopolymerizable material to sequentially project each image of the sequence to generate the structure by progressively photopolymerizing the photopolymerizable material.

A mold unit and base units are formed on a substrate. A covering resin layer is formed by coating a liquid-like resin composition to cover the surfaces of the mold unit and the base unit. When interval between one end of the base unit and the mold unit adjacent thereto is 1, the interval of the plurality of base units is 2, a distance between the center of the ejection opening and the other end of the base unit is L, the height of the unevenness between the surface of the base unit and the surface of the mold unit is H, and the covering resin layer has a thickness H2, when the base unit is established to 230 m, the base unit and the covering resin layer are formed so that the relations 130 m and H=0 m or H2/H3 are satisfied.

An apparatus for spin casting lenses includes a rotatable tube, the rotatable tube defining a longitudinal cavity, wherein the longitudinal cavity is configured to receive molds. According to one exemplary embodiment, the rotatable tube is made of metal and includes a plurality of apertures configured to permit the transmission of actinic radiation.

A curved, three-dimensional, ordered micro-truss structure including a series of first struts extending along a first direction, a series of second struts extending along a second direction, and a series of third struts extending along a third direction. The first, second, and third struts interpenetrate one another at a series of nodes. The series of first struts, second struts, third struts, and nodes form a series of ordered unit cells within the micro-truss structure. The series of ordered unit cells define a curved surface.

A method is disclosed for manufacturing a structured polymeric material. In the method, a body is provided comprising a substantially homogenous precursor polymeric material. An interference pattern of electromagnetic radiation is set up within the body to form a partially cross-linked polymeric material, the interference pattern comprising maxima and minima of intensity of the electromagnetic radiation, the interference pattern thereby causing spatially differential cross linking of the precursor polymeric material to form crosslinked regions having relatively high cross linking density and non-crosslinked regions having relatively low cross linking density, the crosslinked regions and non-crosslinked regions corresponding to the maxima and minima of intensity of the electromagnetic radiation, respectively. The partially cross-linked polymeric material is then contacted with a solvent to cause expansion and crazing of at least some of the non-crosslinked regions to form a structured polymeric material containing pores.
