A solid freeform fabrication object includes a hydrogel including a polymer, water, and a coloring material inclusion substance.

A method includes injection molding a preform using a two phase injection system having a first phase in which a material is injected into the preform and a second phase in which the material is injected into the preform. The preform is disposed in a mold. The preform is blow molded into an intermediate article. The intermediate article is trimmed to form a finished container. The first phase includes injecting a material into the preform to form a single layer of the preform and the second phase includes injecting the material to form inner and outer layers and an intermediate layer between the inner and outer layers. The inner and outer layers include the material and the intermediate layer includes at least one additive. Finished containers are disclosed.

A container, that includes a transparent portion, which reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture. A first liquid component is placed into the interior portion. A second liquid component is poured into the interior portion. The lid of the container is closed to fully enclose the first and second liquid components. The components are agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container. The lid is opened to expose the mixture of uniform color. The mixture of uniform color is poured from the container into a receiving structure. The mixture of uniform color is transformed into a closed-cell polyurethane structure within the receiving structure.

A film for decorative forming includes a layered structure in which a protective layer and a colored layer are arranged sequentially in this order on a base material film, wherein, when a storage elastic modulus of the protective layer at 100° C. is written as E′a(100) and a storage elastic modulus of the colored layer at 100° C. is written as E′b(100), E′a(100) and E′b(100) satisfy conditions (1) to (3): (1) E′a(100)/E′b(100) is less than or equal to 8, (2) E′a(100) is greater than or equal to 10 MPa, (3) E′b(100) is less than or equal to 12 MPa.

In example implementations, an apparatus is provided. The apparatus includes a dispense element, a memory, and a processor. The dispense element dispense a fusing agent onto a build material. The memory stores an absorption level decay data of the fusing agent and at least one adjustment recipe. The processor is communicatively coupled to the dispense element, and the memory. The processor controls the dispense element to dispense the fusing agent based on an adjustment recipe of the at least one adjustment recipe that is selected. The adjustment recipe is selected based on an absorption level determined from the absorption level decay data and an age of the fusing agent.

A method of making an integrated depth sensor window lens, such as for an augmented reality (AR) head set, the depth sensor window lens comprising a sensor lens and an illuminator lens separated by an opaque dam. The method uses a two-shot injection molding process, a first shot comprising an optically clear polymeric material to form the sensor lens and the illuminator lens and the second shot comprising an opaque polymeric material to form the separator of the two.

To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated. The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.

Production process of a composite product (1) comprising a core (2), a first layer (3) comprising a sheet impregnated with a solid polyurethane material, and a polymer-based film (7) applied to the first layer (3), wherein the process comprises: producing a semi-finished product comprising the core (2) and the sheet impregnated by a liquid mixture precursor of the solid polyurethane material; adhering the film (7) to a first half-mould (11) by applying a depression between the film (7) and the half-mould (11); pressing two half-moulds (11, 12) against each other with the semi-finished product interposed between two shaping surfaces (13), so that the film (7) comes into contact with the liquid mixture; with the semi-finished product in the mould, thermosetting the liquid mixture to transform it into the polyurethane solid material so that the film (7) firmly adheres to the first layer (3) and thus producing the composite product (1).
