This invention provides a method for manufacturing parts with a built-in channel. Two kinds of materials with different melting points are used, the material with the lower melting point is a molding element with an arbitrary shape, the material with the higher melting point is powdered, and the material with the low melting point is wrapped and positioned in the powder with the high melting point. When the preparation is completed, the low-temperature material is melted down, and the channel with the random shape is formed after sintering. In the application that the metal parts need supply water, air, or oil, instead of the channel acquired by mechanical splicing or the channel molded by 3D printing technology, this method in the invention is with a wide application range, the lower cost, and the simple and controllable technology, and is suitable for mass production and with very broad market prospects.

An additive manufacturing build plate system includes a plate body defining a build surface and a rear surface opposite the build surface. A peripheral surface extends between the rear surface and the build surface. At least one gripping feature is defined in the peripheral surface, extending inwardly into the plate body between the build surface and the rear surface.

A rare earth permanent magnet includes a main phase containing: a rare earth element R of one or more types including Nd; an element L of one or more types selected from a group consisting of Co, Be, Li, Al, and Si; B; and Fe, wherein crystals which form the main phase belong to P4.sub.2/mnm; some of B atoms occupying a 4f site of the crystals are substituted with atoms of the element L; each distribution of Nd atoms and the atoms of the element L appears along a C-axis direction of the crystals in a plurality of cycles; and the rare earth permanent magnet includes an area where a cycle of the atoms of the element L matches a cycle of the Nd atoms.

One embodiment of the present invention provides a polymeric ammunition having a metal injection molded primer insert.

The present disclosure provides an additive manufacturing method for manufacturing an object. The method comprises depositing successive layers of a granular metal construction material. The method comprises selectively binding a first region of each layer to form a bound shell of the construction material defining an exterior of the object by depositing a binder into the first region surrounding a second region that remains unbound. The method comprises separating the shell and the enclosed unbound construction material from the construction material remaining outside the shell. The present disclosure also provides apparatuses implementing the manufacturing method, and objects manufactured by the manufacturing method.

The method comprises selectively binding first regions of each layer to form a bound shell of construction material defining an exterior of the object. The method comprises selectively binding second regions of each layer to form support portions contacting the shell and which function to internally support the shell against external forces. The present disclosure also relates to apparatuses implementing the manufacturing method, and objects manufactured by the manufacturing method.

There is provided a compact for a magnet which can produce a magnetic member having high coercive force. The compact for a magnet is produced by compression-molding a rare earth-iron-based alloy powder containing a plurality of particles of a rare earth-iron-based alloy containing a rare earth element and iron, wherein the rare earth-iron-based alloy satisfies configurations (a) to (c) below and has 5% by volume or more and 20% by volume or less of voids formed therein. (a) Having a structure containing 10% by mass or more and 30% by mass or less of Sm, 10% by mass or less of Mn, and the balance consisting of Fe and inevitable impurities. (b) A composition, Sm.sub.2MN.sub.xFe.sub.17-x (x=0.1 or more and 2.5 or less). (c) An average crystal grain diameter of 700 nm or less.

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.
