Abstract: An additively manufactured (AM) object may include a body including an opening in an exterior surface thereof, the opening having a shape and a first area at the exterior surface of the body. A mask may be positioned over the opening. The mask has the shape of the opening and a second area that is larger than the first area so as to overhang the exterior surface of the body about the opening. A plurality of support ligaments couple to the mask and the exterior surface of the body at a location adjacent to the opening to support a portion of the mask. A coating can be applied to the object, and the mask removed. The final AM object includes a plurality of ligament elements extending from the exterior surface of the body and through the coating adjacent the opening, each ligament element at least partially surrounded by the coating.

Abstract: A three-dimensional metallic foam is fabricated with an active oxide material for use as an anode for lithium batteries. The porous metal foam, which can be fabricated by a freeze-casting process, is used as the anode current collector of the lithium battery. The porous metal foam can be heat-treated to form an active oxide material to form on the surface of the metal foam. The oxide material acts as the three-dimensional active material that reacts with lithium ions during charging and discharging.

Abstract: According to one or more embodiments presently described, a mixture of lead oxide and lead metal particles may be formed by a method that includes forming a molten metal lead material from a solid lead metal supply material, introducing the molten metal lead material into a reaction zone of a reactor, and contacting the molten metal lead material with an oxidizing gas in the reaction zone to oxidize a portion of the molten metal lead material and form at least solid lead oxide particles and solid lead metal particles. The molten metal lead material may be introduced to the reaction zone in a laminar flow or as atomized molten particles. The weight ratio of formed solid lead oxide particles to solid lead metal particles may be less than 99:1.

Abstract: A method includes additively manufacturing an article in an inert environment, removing the article from the inert environment and placing the article in a non-inert environment, allowing at least a portion the article to oxidize in the non-inert environment to form an oxidized layer on a surface of the article, and removing the oxidized layer (e.g., to smooth the surface of the article). The method can further include relieving stress in the article (e.g., via heating the article after additive manufacturing).
