Abstract
Methods for laser additive manufacture are disclosed in which a plurality of powder layers (and) are delivered onto a working surface (A) to form a multi-powder deposit containing at least two adjacent powders layers in contact, and then applying a first laser energy () to a first powder layer () and a second laser energy () to a second powder layer () to form a section plane of a multi-material component. The multi-powder deposit may include a flux composition that provides at least one protective feature. The shapes, intensities and trajectories of the first and second laser energies may be independently controlled such that their widths are less than or equal to widths of the first and second powder layers, their intensities are tailored to the compositions of the powder layers, and their scan paths define the final shape of the multi-material component.
