A method for producing a smooth aerodynamic surface of an aircraft component is depicted and described. The method includes: provision of an aircraft component with an aerodynamic surface, which has an uneven section, introduction of a liquid or viscous, uncured sealing compound into the uneven section, introduction of a solid, precured sealing body into the uneven section in such a way that the sealing body presses into the sealing compound until the sealing compound at least partially surrounds the sealing body, curing of the sealing compound.

Methods of producing an additive manufactured part with a smooth surface finish include providing a spinning device that has a platform. The part is secured to the platform, where the part is at least partially wetted with uncured resin from a resin pool. The platform is rotated, where a first portion of the uncured resin is retained on the part and a second portion of the uncured resin is removed. The part is cured after the rotating. In some embodiments, methods include creating a compensated design for a part by modifying a desired design to compensate for a first portion of an uncured surface finish material to be retained on the part, and forming the part with an additive manufacturing process according to the compensated design.

A spacer (1) is injection molded by using an injection molding die having resin flow channels that are designed such that a plurality of gates (6) are arranged along the longitudinal direction at a position corresponding to the outer peripheral surface of a side wall part (4) in which a plurality of arc-like peripheral surface parts (2) are connected through a waist part (3). After opening the mold and ejecting the spacer, the spacer is cooled with a runner (7) being connected to the gate (6), and thereafter, the runner (7) is cut off. As a result, when producing a water jacket spacer that is assembled to the inside of the water jacket and controls the flow of cooling water by injection molding, while producing with a high productivity without being affected by design constraints caused by draft angle, deformation in the post-molding cooling step is prevented.

A method of printing a three-dimensional object is provided. The method includes selectively dispensing, layer by layer, one or more materials to form the three-dimensional object; selectively dispensing, layer by layer, one or more materials to form a support construction for the three-dimensional object; selectively dispensing, layer by layer, one or more materials to form a rigid exterior construction around at least part of the support construction, the rigid exterior having substantially similar strength and elasticity to the three-dimensional object; and forming a release construction around the rigid exterior construction, the release construction being between the rigid exterior construction and the three-dimensional object.

A method of creating a three-dimensionally shaped object, the method having: a creation step for creating image data for printing an image on a thermally expandable sheet; a printing step for printing an image on the thermally expandable sheet on the basis of the image data created in the creation step; and a protuberation step for partially protuberating the thermally expandable sheet via thermal expansion by irradiating light toward the image printed on the thermally expandable sheet in the printing step. The creation step creates image data such that a grayscale of an image is set so that a fastening portion that fastens a thermally expandable sheet is either intermittently or continuously surrounded by a region where a protuberation height resulting from the thermal expansion is high.

An apparatus for molding a pouch includes: a die assembly with a die; a stripper assembly to press and fix both sides of a pouch film disposed on the die; and a punch assembly with a punch to mold an electrode assembly accommodation part in the pouch film. The stripper assembly includes: a stripper disposed at a punch assembly lower portion to press and fix the pouch film; a stripper driving piece at a punch assembly upper portion to provide force so that the stripper presses the pouch film; and a connection part to connect the stripper driving piece to the stripper to transmit the force. The connection part includes: two or more connection rods coupled to the stripper; a connection bar coupled to the stripper driving piece; and a connection piece to connect one or more of the connection rods to the connection bar to transmit the force.

A tool for use in consolidation of a fibre-reinforced component has an outer casing supported by an internal structure. The outer casing has a first contact surface, which is provided for the purpose of resting flat against the component during the consolidation of the component and predetermining a shape of the component in some section or sections. The internal structure and the outer casing are configured in such a way that, when the tool is heated from an initial temperature to a consolidation temperature required for the consolidation of the component, the tool expands in such a way perpendicularly to the first contact surface that a defined first pressure is exerted on the component by the first contact surface. The use of a component of this kind is furthermore claimed and described.

An embodiment relates to a vehicular lamp and a vehicle comprising the same, the vehicular lamp comprising: a lens portion; and a light source portion for emitting light toward the lens portion, wherein the lens portion comprises a body having least one curved surface and a film portion arranged on one side of the body so as to generate a 3D stereoscopic image using the light, and the lens portion is injected in an in-mold labelling (IML) type using a mold. Accordingly, the design-related degree of freedom can be improved, thereby providing an enhanced aesthetic appearance, and the manufacturing process can be simplified, thereby improving the productivity.
