  • Patent number: 12275065
    Abstract: Atomic Layer Deposition (ALD) and Molecular Layer Deposition (MLD) provide precise and conformal coatings that are employed to modify the properties of powders for additive manufacturing (AM). We have surprisingly discovered that use of a limited number of ALD cycles can impart improved flowability. In various aspects, the coating may provide one or more advantages such as novel material properties, increased flowability, improved sintering, enhanced stability during storage, and prevention of premature sintering.
