A method for continuous manufacture of permanent magnets. A material sheet is formed into an open tube, having a lengthwise opening. Magnetic powder may be poured into the lengthwise opening on a continuous basis. The tube opening is then formed closed and sealed. The magnetic powder is magnetically pre-aligned by subjecting it to a first magnetic field. The tube containing the powder may be compressed into a desired shape, forming an elongated permanent magnet. After compression, the elongated magnet is magnetized by a second magnetic field in two-step process, wherein the elongated permanent magnet is subjected to a magnetic field from first magnetizing coil that is pulsed with a first electric current in a first direction, followed by a second magnetizing coil being pulsed with a second magnetizing electric current in a second direction. The elongated magnet may be formed into any arbitrary shape, such as a ring or coil.

Build material application device for additively manufacturing a three-dimensional object, the build material application device comprising: at least one blade-like build material application member; at least one support unit for supporting the blade-like build material application member, wherein the support unit comprises at least two support unit members defining a receiving section for receiving a blade-like build material application member, a first support unit member is moveably supported relative to a second support unit member between a first operating position, in which a holding force is exertable or exerted on a blade-like build material application member received in the receiving section, and a second operating position, in which no holding force is exertable or exerted on a blade-like build material application member received in the receiving section.

The devices, systems, and methods of the present disclosure are directed to powder spreading and binder distribution techniques for consistent and rapid layer-by-layer fabrication of three-dimensional objects formed through binder jetting. For example, a powder may be spread to form a layer along a volume defined by a powder box, a binder may be deposited along the layer to form a layer of a three-dimensional object, and the direction of spreading the layer and depositing the binder may be in a first direction and in a second direction, different from the first direction, thus facilitating rapid formation of the three-dimensional object with each passage of the print carriage over the volume. Powder delivery, powder spreading, thermal energy delivery, and combinations thereof, may facilitate consistently achieving quality standards as the rate of fabrication of the three-dimensional object is increased.

A system and method for designing and manufacturing free-form objects made of composite material and optimised in their weight ratio and load capacity; a system for the design and manufacture of said objects, and the objects resulting from said method. Using three-dimensional (3D) design computer programs and computer calculation programs, the design of a composite material object is obtained, with a specific shape and orientation of its component fragments, optimised to be light and at the same time to meet a required specific mechanical and/or structural performance. Subsequently, a mould of at least two parts is obtained from this design and the parameters of said design are transformed into instructions so that one or more automated manufacturing machines deposit fragments of wood or another material onto the lower part of the mould in specific orientations, calculated to minimise the weight of the object and optimise its load capacity. Then, with the addition of one or more binders, the object is pressed between the parts of said mould. Finally, the new manufactured object is obtained by removing it from the mould.

The present disclosure relates to a hierarchical wear part including a reinforced portion comprising zirconia or an alumina-zirconia alloy. The reinforced portion also includes centimetric inserts with a predefined geometry. The inserts include micrometric particles of metal carbides, nitrides, borides, or intermetallic compounds bonded by a first metal matrix. The inserts are inserted into a reinforcement structure infiltrated by a second metal matrix, the reinforcement structure having a periodic alternation of millimetric areas of high and low concentration of micrometric particles of zirconia or alumina-zirconia alloy. The second metal matrix is different from the first metal matrix.

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

A powder filling method includes introducing a tube into a can so that the lower end of the tube is near the bottom of the can. The powder in the can is introduced through the tube. The proximity of the lower end of the tube to the powder is controlled by retracting the tube as the powder fills the can.
