A particulate for an additive manufacturing technique includes a particulate body formed from a particulate material and a coating disposed over particulate body. The coating includes a carbonaceous material that has a reflectivity that is lower than a reflectivity of the particulate material to reduce an energy input requirement of the particulate such that less energy is necessary to fuse the particulate into a layer of an article fabricated using the additive manufacturing technique. A method of making particulate is also disclosed.
