1. A replacement assembly for replacing a damaged portion of a component, the replacement assembly comprising:
a replacement piece including a first plurality of layers with each layer of the first plurality of layers formed on top of a prior formed layer of the first plurality of layers, the first plurality of layers arranged to define a curved leading-edge portion and a first interface surface, the first interface surface defined by a first continuous curve, wherein each layer of the plurality of layers includes particles of a base material that are attached to one another via a sintering process such that the particles of base material are not melted, and wherein each layer of the first plurality of layers defines a thickness of between 10 microns and 100 microns; and
an attachment piece including a second plurality of layers with each layer of the second plurality of layers formed on top of a prior formed layer of the second plurality of layers, the attachment piece arranged to fit between the first interface surface and the component to fixedly attach the replacement piece to the component to replace the damaged portion of a component.
