Abstract
A process for manufacturing a multi-material part by additive manufacturing, includes the following steps: a) a step of providing a pre-treated metal powder comprising grains and an oxidized and porous layer on a surface of the grains; b) a selective laser powder-bed fusion step comprising implementation of steps i) and ii) as follows: i) a step of forming a layer from the pre-treated metal powder; ii) a step of melting by laser the layer, the melting step being carried out under a reactive atmosphere and comprising changing parameters of application of the laser so that at least a first region of the layer is converted so as to lower the electrical conductivity thereof, thus forming a dielectric, and so that at least a second region of the layer is densified without converting it, the at least a first region being formed when the parameters of application of the laser allow a first energy density to be applied to the first region and/or the laser beam to be kept for a first dwell time on the first region, the at least a second region being formed when the parameters of application of the laser allow a second energy density to be applied to the second region and/or the laser beam to be kept for a second dwell time on the second region, and the first energy density being higher than the second energy density and/or the first dwell time being longer than the second dwell time. A part obtained using the process is also provided.
