A dissimilar material joined three-dimensional laminated and shaped object is shaped using a three-dimensional laminating and shaping apparatus. The three-dimensional laminating and shaping apparatus includes a material supplier that supplies materials of a three-dimensional laminated and shaped object to a shaping surface, an irradiator that irradiates the materials with a light beam, and a controller that controls the material supplier. The three-dimensional laminated and shaped object is a joined member obtained by joining dissimilar materials. The controller controls the material supplier to form a graded composition of the materials in a boundary region between the dissimilar materials of the three-dimensional laminated and shaped object.

A method of manufacturing a TiAl alloy impeller includes a blank preparation step in which a blank of the TiAl alloy impeller is prepared, wherein the blank has a shaft portion and a plurality of blades, and a thickness of an outer edge of each of the blades of the blank is set so as to be larger than a thickness of an outer edge of a blade of the TiAl alloy impeller, and an additional work step in which an additional work is performed on each of the blades of the blank. In the additional work step, the additional work is performed on a first surface of a portion that includes at least the outer edge of each of the blades or the first surface and a second surface of the portion thereof.

The invention relates to a cable guide apparatus, wherein the cable guide apparatus comprises: a guide apparatus, a slide which is movably guided in the guide apparatus, a deflection roller which is connected to the slide, a first tension weight, a cable pull apparatus which connects the first tension weight to the slide guided in the guide apparatus, wherein the connection cable has a free end and a fixed end connected to a connection apparatus and extends over the deflection roller, a second tension weight and a second guide apparatus in which the tension weights are each movably guided, such that the connection cable extending over the deflection roller is preloaded in a first displacement region of the free end by a force generated by the weight force of the first tension weight and is preloaded in a second displacement region of the free end by a force generated by a total of the weight forces of the tension weights.

A calibration method serves for calibrating a manufacturing device for additively producing a three-dimensional object by applying layer by layer and selectively solidifying a building material. The manufacturing device comprises at least two scanning units, each of which is capable of directing a beam to different target points in the working plane, which are located within a scanning region assigned to the respective scanning unit, wherein the scanning regions region of the at least two scanning units overlap in an overlap area. At least a first of the at least two scanning units is assigned a first monitoring unit whose monitoring region extends to a target point of the first scanning unit and its proximity, wherein a change of a position of the monitoring region is carried out as a function of a change of a position of the target point.

A method is disclosed for producing a friction brake body, in particular a brake disc, which has a main part with a frictional contact region. A wear protection layer is produced on the frictional contact region by way of laser cladding using a laser beam oriented towards the frictional contact region. The wear protection layer is produced by at least one pulverulent additive during the laser cladding. At least two pulverulent additives are added simultaneously such that the dwell time thereof in the laser beam differs.

A method including depositing a first material on a first member by an additive manufacturing process in a pattern intended to aid in an assembly of the first member and at least a second member and inserting the first member at least partially into the second member, with the first material being guide for insertion.

The present disclosure is directed towards a method of manufacturing a permanent magnet such that the magnet defines a channel for allowing circulation of a coolant through the permanent magnet, or defines a channel for allowing circulation of the coolant through an interface between the permanent magnet and a substrate. Magnets made by this method may be useful for manufacturing and/or operating a machine, such as a motor, engine, or sensor.
