A tube material is formed by continuously extruding a thermoplastic resin material in the shape of a cylinder that has a thickness of 100 μm and a circumferential length of 800 mm. After that, in a polishing process, the tube material is rubbed with a lapping tape of #2000 while being rotated in one direction at a fixed speed, so that circumferential stripes are formed on the outer circumferential surface of the tube material. Then, the circumferential stripes are thermally transferred by pressing the outer circumferential surface of the heated tube material against a mold surface that is finished in the shape of circumferential stripes by a thermal transfer process.

In an embodiment, a fluid flow structure includes a micro device embedded in a molding. A fluid feed hole is formed through the micro device, and a saw defined fluid channel is cut through the molding to fluidically couple the fluid feed hole with the channel.

A manufacturing method of a liquid supply component in which a liquid supply path is formed between a first constituent component and a second constituent component that are joined with molten resin. The method includes a first step of preparing these constituent components, a second step of causing the constituent components to face each other and forming an orifice portion and a reservoir portion between a mold and a surface of either of the constituent components, and a third step of pouring the molten resin between the constituent components so that it flows into the reservoir portion through the orifice portion.

A method for manufacturing a check valve unit as a liquid flow path member, in which the liquid flow path member includes, in a flow path direction of ink, a first flow path member constituting one side of a flow path, a second flow path member constituting another side of the flow path, and a check valve including a valve body configured to stop a backflow of the ink in the flow path and a check valve holding member configured to hold the valve body, the method includes a welding step for welding the first flow path member or the second flow path member, and the check valve holding member together, and also welding the first flow path member and the second flow path member together.

A method for printing on a multi-dimensional object may include creating a customized object holder for the multi-dimensional object by heating a thermoforming sheet to a thermoforming temperature, molding the heated thermoforming sheet around at least a portion of a multi-dimensional object to form a holding portion for the multi-dimensional object, creating one or more printable areas on the molded thermoforming sheet, and applying one or more datum points on the molded thermoformed sheet. The one or more datum points may be configured to provide information relating to position of the one or more printable areas to a print system.

A method of producing a molded product includes preparing a mold for insert molding, setting an insert member, forming a cavity in a condition in which the insert member is disposed by closing the mold and injecting a molten resin into the cavity. The mold for insert molding includes first and second molds, and the first mold has a guide surface provided at a part corresponding to a trunk portion of the molded product within a wall surface defining a groove portion which constitutes a part of the cavity. The insert member is set at the groove portion of the first mold while the projecting portion being guided by the guide surface.

An extrusion head for a three-dimensional printer is disclosed including a feed tube, a heater, a cooler, and a bridge. The feed tube can be made of metal and has an inlet for receiving a forwardly driven filament of solid deposition material, an outlet, a downstream portion adjacent to the outlet, an upstream portion upstream from the downstream portion, and an internal passage extending from the inlet to the outlet. The heater is thermally coupled with the downstream portion of the feed tube for heating a filament to provide softened fluid deposition material. The cooler is thermally coupled with the upstream portion and spaced generally axially from the heater to define a generally axially extending gap traversed by the feed tube. The bridge traverses the gap and provides a rigid mechanical connection between the heater and the cooler.

There is provided a liquid supply member capable of suppressing deformation of a liquid supply path and decrease in sealing property of a liquid supply path, during molding, and a manufacturing method of the liquid supply member. For that purpose, in die-slide injection molding that combines two components, a protection portion that protects a part of one component easily affected by heat and pressure, is provided on the other component.

The invention relates to a method (100) for producing an image structure (12) according to an image specification (20), in particular for a letterpress process and/or intaglio printing process, characterized in that the following steps are carried out: a) providing a base (10) for receiving the image structure (12), b) producing an image structure (12) on the base (10) so that an image layer (11) is formed on the base (10) by means of the image structure (12).
