摘要： A method for manufacturing a metal component includes the following steps: a shell made of a titanium-based material is provided, the shell having a first surface and a second surface remote from the first surface; a covering layer made of a titanium fire-resistant material is produced by additive manufacturing on the shell such that the covering layer at least partially covers the first surface and/or the second surface; and, after the additive manufacturing step, the metal component is heat treated at a temperature of between 200° C. and 1000° C.

摘要： Manufacturing of a part by local irradiation of a material that can be sintered, melted or photopolymerized, by: providing a volume of the material for manufacturing the part and compressing the volume by applying a pressure; defining, in the volume, a plurality of different target volumes, the combined target volumes defining the part to be manufactured; for each target volume, maintaining the pressure applied to the volume and simultaneously irradiating the target volume with at least two continuous beams that converge in the target volume; releasing the obtained part from the rest of non-irradiated material. The material is partially transparent to the beams; the energy applied to the target volume by each beam is greater than Ethreshold, the sum of the energies applied to the target volume by each of the beams is greater than or equal to Etransformation threshold.
