Methods for making a microstructured tool having interspersed topographies are disclosed, and the production of articles therefrom. The article has a major surface including first microstructural features and second microstructural features arranged in a pattern visible at least when viewed normal to the first major surface. The first and second microstructural features are different relative to each other, and are selected from the group consisting of cones, diffraction gratings, lenticulars, segments of a sphere, pyramids, cylinders, fresnels, and prisms.

A method for 3D printing an object with at least one wall (2) having a first surface and a second, opposite surface, wherein the first surface is intended to serve as an optical functional surface, wherein the wall is formed by printing one track (16) on top of another track (17). An orientation of the object during printing is selected such that the wall has a tangent (or tangent surface) non-parallel to the z-axis, such that the first surface faces away from the x-y plane and the second surface faces the x-y plane. According to the invention, the 3D object is thus oriented during printing such that the first surface, intended to be used as an optical functional surface, faces away from the x-y plane, i.e. typically away from the support or platform on which the 3D object is printed upon. By ensuring this orientation during printing, the first surface becomes smoother than the second, opposite surface of the wall.

A rotating reflector is a resin rotating reflector including: a rotating part; and a blade provided around the rotating part and functioning as a reflecting surface, wherein the rotating part has a hole in which a rotary shaft is inserted.

A biaxially oriented polyester reflection film according to an embodiment of the present invention includes: a core layer having a plurality of voids, and containing homo-polyester, copolymer polyester, a resin incompatible with polyester, and inorganic particles; and a skin layer formed at least one surface of the core layer, and containing homo-polyester, copolymer polyester, and inorganic particles, wherein the biaxially oriented polyester reflection film is formed to have a plurality of light focusing structures, each of which has a concave center portion, and which are arranged in a grid pattern.

The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.
