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.

Methods of printing a three-dimensional object, layer by layer are provided. Layers are formed by a bulk inner region which may be formed by depositing a transparent material, a white material, a colored material or a combination thereof, and a color outline which includes voxels formed by depositing a colored building material.

A decorative sheet includes a design layer, a primer layer and a surface protective layer formed by cross-linking and curing an ionizing radiation curable resin composition in this order on a base material. A surface of the surface protective layer is smooth. A ten point average roughness RzJIS on a rear face of the decorative sheet and a thickness T of the base material satisfies the following equation (I); and an arithmetic average roughness Ra on the rear face and a thickness T of the base material satisfies the following equation (II):
T×0.30≥RzJIS  (I)
T×0.20≥Ra≥T×0.005  (II)
Or an arithmetic average roughness Ra on a rear face of the decorative sheet is 1.0 to 10.0 μm. A decorated resin molded article is produced by integrating the decorative sheet with an outer surface of a resin molded article at the same time as injection molding.

A color 3D printer and its method of use are disclosed. The color 3D printer uses a number of chambers to dye a filament to a given color. This colored filament is then extruded, pursuant to an associated 3D model of an object, to produce varying colored physical objects, on demand, with the use of a single filament and a single print head. Further, the color 3D printer features a waste management apparatus which provides a number of ways to dispose of waste fluid.

An implement having a base structure with a core component and a shell component that surrounds the core component. The core component may include a body formed of a rigid material and decorative elements embedded within the body. The shell component may be formed of a substantially transparent material so that the decorative elements of the core are visible through the shell component.

A blow molded article obtained by blow molding of a preform made via parallel flow coinjection, having a wall formed by 3 layers in at least a region wherein the outside layer is transparent and the inner layer comprises an effect pigment visible through the transparent layer. Articles according to the invention have an improved gloss, low haze and higher resistance to delamination than previous articles. The invention relates also to preforms for making articles as described and to methods for making preforms and articles.

The invention provides a polyester resin for heat-shrinkable film which contains terephthalic acid as a main component of a dicarboxylic acid component, contains ethylene glycol as a main component of a diol component, and contains from 18 to 32% by mol of neopentyl glycol and from 8 to 16% by mol of diethylene glycol when a total amount of the whole diol component in total polyester resin components is taken as 100% by mol. The polyester resin has an intrinsic viscosity (IV) of from 0.70 to 0.86 dl/g, a carboxyl end group concentration (AV) of from 8 to 25 eq/t, and a color b value of from 1.0 to 12.0 in an L*a*b color system. The invention also provides a heat-shrinkable film prepared from the aforementioned polyester resin, as well as a heat-shrinkable label and packaged product.

The present specification relates to a decorative member comprising a base and inorganic layers comprising a first light absorption layer, a light reflection layer, and a second light absorption layer sequentially provided on the base, in which ΔE.sub.12 indicated in Equation 1 is 1 or more, and a method of manufacturing the decorative member.

A molded object, which is thermoformed by a thermoplastic wear-resistant molding membrane, has a plurality of concave-convex parts; the molded object comprises: a polycarbonate polyurethane (PU) layer; a thermoplastic polyurethane (PU) layer with ductility and elasticity, disposed on one surface of the polycarbonate PU layer; and an intermediate PU layer disposed between the polycarbonate PU layer and the thermoplastic PU layer; the polycarbonate PU layer is a surface layer of the molded object, the thermoplastic PU layer is an inner layer of the molded object; the concave-convex part comprises a plurality of upwardly protruding pressing parts, each of the pressing parts has a top wall and a peripheral wall extending downward from a periphery of the top wall; at least one character is disposed on the top wall of each of the pressing parts, and the character is formed by at least removing a material of the polycarbonate PU layer, so that the top wall forms a hollow part penetrating the polycarbonate PU layer.

The object of this invention is to provide optical articles having one or more transmittance-attenuating dyes. Each dye attenuates transmission of a certain wavelength range. Different dyes can be combined in different concentrations to tune the transmittance spectrum through a lens. The transmittance-attenuating dyes can be incorporated into different optical articles using different production methods.
