A container body comprises a base, a side wall extending from the base and a neck portion arranged to engage a closure for the container body, wherein: (i) said container body includes a cyclic olefin copolymer (COC) and polyester; or (ii) said container body includes a polymethylpentene (PMP) and polyester; wherein, in both cases (i) and (ii), the side wall of the container body has an L* of at least 90 and the neck portion has an L* of at least 84.

A method of printing a three-dimensional object, comprises: for each of a plurality of arrays of nozzles, activating a subset of nozzles of the array to dispense a respective building material from the subset, so as to form an interleaved scan pattern of dispensed materials. The method comprises hardening the interleaved scan pattern, and repeating the activating and the hardening to form a stack of hardened interleaved scan patterns.

Materials that exhibit stress-induced porosity, and methods of making and using the same, are described.

The present disclosure provides a light curing non-transparent material for 3D printing and a preparation method thereof, a 3D printed product and a 3D printer. The light curing non-transparent material for 3D printing provided by the present disclosure can be used to print non-transparent 3D printed products without adding white pigments such as white pigments powder, and therefore has the characteristic of high stability, and also ensures fluency of the 3D printing process, good quality of the 3D printed products, as well as good performances of the 3D printer that containing light curing non-transparent material for 3D printing.

An illuminated emblem assembly includes a multi-component outer lens having an exterior surface and an interior surface further comprising an externally visible area to be illuminated, an inner lens having an exterior surface and an interior surface, a printed circuit board assembly, a heat sink, a housing for the inner and outer lenses, and at least one light source, wherein the at least one light source is offset from the externally visible area to be illuminated. A method of manufacturing the illuminated emblem assembly includes injection molding the multi-component outer lens, providing the inner lens, providing the housing for the inner and outer lenses, providing the at least one light source, and assembling the inner and outer lenses and the at least one light source within the housing to obtain the illuminated emblem assembly.

Manufacturing a pre-molded stack of one or more lenses to be installable on a curved substrate such as a vehicle windshield includes placing a moldable stack of one or more lenses and adhesive layer(s) on a mold, applying heat and pressure to the moldable stack to produce a pre-molded stack of one or more lenses from the moldable stack, and removing the pre-molded stack from the mold. The pre-molded stack may have a compound curvature, which may match a curvature of the curved substrate. The mold may be formed using three-dimensional shape data derived from the curved substrate, such as by optically scanning the curved substrate.

The present invention relates to equipment covers. More particularly, the present invention relates to a method of making an equipment cover, the method comprising: moulding a cover from a substantially transparent or translucent polymer, optionally a thermoplastic polymer, to form a cover having a textured outer surface and a generally smoother inner surface; and applying a coating having reflective components to the inner surface.

Article having a body portion including one or more walls surrounding an interior space. The one or more walls have an inner surface, an outer surface, a wall thickness, a transparent portion, and one or more aesthetic regions having oblong voids provided between the inner surface and the outer surface within an outermost 70% of the wall, and the one or more aesthetic regions are provided in a predetermined pattern.

The disclosure relates to a method of concealing a non-optically transparent component of an optical article. The method comprises—providing (S7) an optical article comprising: —an optical lens comprising an eyeball side facing an eye of a person when the optical article is worn by the person and an object side opposing the eyeball side, the optical lens comprising on the object side an eyewear shape section extending from an outer contour of the optical lens to an inner contour, and—a non-optically transparent component extending at least partly over the eyewear shape section, and—concealing (S8) the non-optically transparent component by covering at least part of the eyewear shape section of the optical lens using an opaque material.
