Aspects of the disclosure are directed to methods and/or apparatuses involving one or more of a conductive polymer, deposition of a conductive polymer and 3D (three-dimensional) printing of a continuous bead of material. As may be implemented in accordance with one or more embodiments characterized herein, a 3D structure is formed as follows. A stacked layer is formed by depositing a continuous bead of material along an uninterrupted path that defines a first layer of the 3D structure. A sidewall of the 3D structure is formed with opposing surfaces respectively defined by successive stacked layers of the 3D structure by, for each stacked layer (including the first layer), depositing the continuous bead of material along the path and with a surface thereof in contact with a surface of the continuous bead of material of an adjacent one of the stacked layers.

An elastomer molded body for a medical device includes an elastomer portion and a filler. The elastomer portion contains a crosslinked fluorine-based elastomer. The filler is formed from a plurality of particles each of which has aspect ratio of 5 or more and specific surface area of 3 m.sup.2/g or more and 10 m.sup.2/g or less. The aspect ratio is defined as a ratio of a dimension in a long axis direction thereof to a dimension in a short axis direction thereof. The filler has an uneven distribution in a surface layer part of the elastomer portion and is oriented in a direction along a surface of the elastomer molded body.

A multi-layer direct blow bottle in which a metallic layer containing a metal pigment having an average thickness of not more than 1 m dispersed in a resin is formed at a position where it is visible from the outer surface side.

A molding method for a synthetic resin molding that includes a molding body, a bent portion, and a flange. The bent portion and the flange are continuous in a longitudinal direction of the side edge. The flange includes a wide portion and a narrow portion. The molding method for the synthetic resin molding includes arranging a gate at a position corresponding to an end of one side of the flange in a longitudinal direction, performing injection molding using a colored resin material containing a luster agent kneaded in the material, and forming a protrusion along the side edge in the longitudinal direction at a back of a boundary portion between the flange and the molding body to reduce interference of flow of the molten resin from the flange toward the molding body during the injection molding.

A molding method for a synthetic resin molding reduces a disturbed flow of molten resin at a side edge of a molding body during injection molding, and allows the design surface of the molding body to have aesthetic appearance. The synthetic resin molding includes a bend arranged on a side edge of the molding body and bending toward its back surface, and a flange protruding laterally from the bend and including a notch. The molding method includes arranging a gate at a position corresponding to an end of one side of the flange in a longitudinal direction and performing injection molding using a colored resin material containing a luster agent kneaded in the material, and forming a thin portion of the bend in a longitudinal direction of the bend to form a groove on a back surface of the bend.
