Light leakage from integrally molding a decorative sheet and a connector insert is prevented. A molded article includes a display portion through which light can pass. A molded article body of the molded article includes a second molded portion made of a light-transmitting resin transmitting light guided to the display portion and a first molded portion made of an opaque resin having lower light transmittance than the second molded portion. A decorative sheet is integrally molded with the molded article body and includes a decorative portion that embellishes the display portion. A light-transmitting touch sensor sheet is integrally molded with the molded article body and transmits light that passes through the display portion. The molded article body includes a shade structure that is at least partly disposed around an outer peripheral edge of the decorative sheet and suppresses light passing through the light-transmitting resin.

A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.

A method for manufacturing a skin from a plastic material. The method includes the following steps: producing a first part of the skin having a property according to a first level, producing a second part of the skin extending the first part and having the property at the first level on a first edge in contact with the first part and a second level on a second edge in contact with a third part of the skin extending the second part, and producing the third part of the skin having the property at the second level, the production steps being carried out using additive technology, such as 3D printing. Also provided is a skin obtained by such a method.

An oral care implement having a multi-component handle. The oral care implement may include a head and a handle. The handle may have a front surface, a rear surface, and opposing first and second lateral surfaces. The handle may include an elongated handle body, a grip cover, and a transparent component. The elongated handle body and the grip cover may be opaque. The elongated handle body may form a portion of the front surface of the handle and the grip cover may form a portion of the rear surface of the handle. The transparent component may form a portion of each of the first and second lateral surfaces of the handle. Thus, the transparent component may form a window through the lateral surfaces of the handle.

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 optical lens assembly has a central axis and includes at least one dual molded lens element. The dual molded lens element includes a light transmitting portion and a light absorbing portion, wherein the light transmitting portion includes an optical effective region and a lens peripheral region, and the lens peripheral region surrounds the optical effective region. The light absorbing portion surrounds the optical effective region. The light transmitting portion and the light absorbing portion are made of different plastic materials with different colors, and are integrally formed by an injection molding. The light transmitting portion or the light absorbing portion includes a plurality of annular convex structures, and the annular convex structures surround the central axis.

A printed film with mounted light emitting diodes encapsulated in a light guide includes a printed film assembly. The printed film assembly includes multiple light emitting diodes. A light guide is injection molded onto a first side of the body covering the light emitting diodes. A light transmissive polymeric material coating layer is applied by injection molding to a second side of the body opposite to the first side. An overmolded component has the printed film assembly embedded therein, with the coating layer exposed for visibility of light from the light emitting diodes when at least one of the light emitting diodes is energized.

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

An optical element for a lighting device of an automotive vehicle. The optical element includes a first portion configured to transmit electromagnetic (EM) radiation therethrough, the EM radiation including visible wavelengths and an ablation process wavelength. Also included is a second portion configured to absorb at least the ablation process wavelength, the second portion being in contact with the first portion to define an ablation process boundary which separates a surface of the first portion from an adjacent surface of the second portion. A patterned optical coating is provided on the optical element such that the optical coating material is provided on at least a part of the surface of the second portion, but not provided on the surface of the first portion.

In one embodiment there is provided a protective case for an electronic device. The case has a substantially transparent planar back surface. The substantially transparent planar back surface is made from a compostable biopolymer material configured to form a rigid back surface and wherein the substantially transparent planar back surface has a terminal outer periphery edge. An outer bumper formed into a continuous side wall extends transversely from the planar back surface. The continuous side wall has an inwardly extending edge such that the outer bumper is configured to form fit around an electronic device. The outer bumper is made from a compostable biopolymer material configured to form into the outer bumper that is softer then the rigid back surface, and wherein the outer periphery edge of the transparent planar back surface is over-molded into the outer bumper.
