    Abstract: Method of forming porous structures which are permeable in two or more dimensions. The method comprises forming successive layers of material on top of one another and, for each layer, selectively fusing powdered material according to a geometry having voids to be permeable in one or more dimensions, and selectively eroding material from the layer to create additional permeability.
    Type: Application

  • POROUS STRUCTURES
    Publication number: 20190054534
    Abstract: Method of forming porous structures which are permeable in two or more dimensions. The method comprises forming successive layers of material on top of one another and, for each layer, selectively fusing powdered material according to a geometry having voids to be permeable in one or more dimensions at an energy density which is sufficient to only fully fuse a portion of said material to create additional permeability.
