A fuel injector for fuel injection systems of internal combustion engines has an excitable actuator for activating a valve closing element, which forms a sealing seat together with a valve face implemented on a valve seat element. Multiple spray-discharge openings are implemented in the valve seat element downstream from the valve face. The fuel injector is distinguished in that the spray-discharge openings include at least one upstream first spray-discharge opening section and one downstream second spray-discharge opening section having a different opening width and a wall area of the second spray-discharge opening section of all spray-discharge openings on a semi-circle runs either parallel or at a right angle to the longitudinal axis of the valve seat element having the spray-discharge openings. The valve seat element is manufactured using metal injection molding methods.

There is provided a 3D printing build material container (1). The container (1) comprises a reservoir (3) and a reinforcement structure (4). The reservoir is to hold build material. The reinforcement structure is attached to the reservoir at at least one selected location. The reservoir and reinforcement structure are to permit reconfiguration of the container from a relatively flat configuration to an in-use configuration in which the reservoir is tillable with build material.

The additive fabrication processing method includes: a setting step of setting a speed command value indicating the speed of a processing head, and a metal powder supply amount command value indicating a supply amount of the metal powder corresponding to the speed command value; an acquisition step of acquiring both a speed indicating the speed of the processing head at which actually moving and an actual distance indicating a distance actually between the processing head and a surface on which spraying metal powder; and a supply amount calculation step of calculating a metal powder supply amount by correcting the metal powder supply amount command value based on the speed and the actual distance, so that a program command route and a processed surface match.

Disclosed are an apparatus and method for densifying or compacting powder material in the supply bin of an additive manufacture machine to improve the quality of the object being made. For example, a removable or portable apparatus can be applied to the surface of the supply bin once the bin has been filled. The apparatus can include a vibrational component that agitates the underlying powder to compact the material. The apparatus can then be removed during the remainder of the additive manufacturing process, which then follows in its normal course. A vacuum can also be used the remove of air or other gases that are emitted during the compaction process, for example, as voids are filled during densification.

A method for creating a metallurgic component comprises creating a thin-walled container corresponding to a shape of the metallurgic component from a metal. If powder metal is not already in the container (depending on a method of creating the container), the thin-walled container is filled with powder metal. A quick-can device is fixed to the thin-walled container, and the powder metal is consolidated inside the thin-walled container (e.g., in a hot isostatic press). During consolidation, pressure within the thin-walled container is monitored and a desired pressure differential between an inside of the thin-walled container and an outside of the thin-walled container is maintained by the quick-can device.
