An additive manufacturing system includes a foil supply drum, a melting energy source, and a processor. The foil supply drum is configured to be rotated for dispensing a foil sheet over a substrate surface supported by a build element. The melting energy source is configured to direct at least one melting energy beam onto a non-melted region of the foil sheet located over the substrate surface. The processor is configured to execute computable readable program instructions based on a three-dimensional digital definition of the object, and control the melting energy beam to selectively melt at least some of the non-melted region into melted portions forming a material layer of the object onto the substrate surface while separating the melted portions from non-melted portions, and command rotation of the foil supply drum for dispensing the foil sheet during manufacturing of the object in correspondence with the digital definition.

The present application relates to a composite material. The present application can provide a composite material having high magnetic permeability and also having excellent mechanical properties such as flexibility. The composite material may be used in various applications, and for example, may be used as an electromagnetic-wave shielding material and the like.

A method is provided for the production of a wound nanocrystalline magnetic core in which a nanocrystalline metal strip made of (Fe.sub.1-aM.sub.a).sub.100-x-y-z--Cu.sub.xSi.sub.yB.sub.zM.sub.X.sub. is pre-wound to form a first coil. An insulating foil is provided that is coated with an adhesive on at least one side. An adhesive is applied to the nanocrystalline metal strip to laminate the insulating foil onto the metal strip and thereby to stabilise the metal strip as it is wound off the coil. The laminated nanocrystalline metal strip and the insulating foil are bifilar wound to form a bifilar, layer-insulated coil.
