摘要： The present invention relates to a method of manufacturing a ceramic article (3) from a metal or metal matrix composite preform (1) provided by 3D-printing or by 3D-weaving. The preform (1) is placed in a heating chamber (2), and a predetermined time-temperature profile is applied in order to controllably react the preform (1) with a gas introduced into the heating chamber (2). The metal, the gas and the time-temperature profile are chosen so as to induce a metal-gas reaction resulting in at least a part of the preform (1) transforming into a ceramic. Preferred embodiments of the invention comprises a first oxidation stage involving a metal-gas reaction in order to form a supporting oxide layer (5) at the surface of the metal, followed by a second stage in which the heating chamber (2) is heated to a temperature above the melting point of the metal to increase the kinetics of the chemical reaction. The invention also relates to a number of advantageous uses of a ceramic article manufactured as described.

摘要： The present invention relates to a method of manufacturing a component 1 by additive manufacturing. The method comprises providing a work surface 2 on which the component 1 is to be manufactured, and providing at least one deposition material 3 from which the component 1 is to be composed. The deposition material, typically in the form of wire, is advanced to a localized deposition area 4 where it is added to the component 1 being manufactured. The method further comprises focusing at least one light beam 5 of incoherent light emitted from at least one heating source 6 in the deposition area 4 so that the deposition material 3 is deposited for building up the component 1. At least one light focusing mirror 7 and/or lens 11 is used to focus the incoherent light in the deposition area 4. The invention further relates to the use of such a method in space, such as on a space station, on a space craft or on parabolic flights for testing.
