  • Methods for forming strengthened additive manufacturing materials and strengthened filaments for use
    Patent number: 11554550
    Abstract: An example method for forming a strengthened additive manufacturing material includes coating a surface of an additive manufacturing material with a solution including reinforcement particles, and causing a solvent of the solution to evaporate and the reinforcement particles adhere to the surface of the additive manufacturing material. An example strengthened filament includes a polymer filament having a surface, and reinforcement particles included on the surface of the polymer filament in a substantially uniform coating.
    Type: Grant

  • Sheet-based additive manufacturing methods
    Patent number: 11027485
    Abstract: A method of fabricating a part includes stacking sheets of fusible material to form a stack. The method also includes directing a laser beam through at least one sheet of the stack. The method also includes transferring energy from the laser beam to multiple locations on at least one interface between adjacent sheets of the stack, according to a predetermined pattern corresponding with a design of the part, to form corresponding multiple molten regions. The molten regions are conjoined together to form a fused portion of the adjacent sheets. The fused portion of the adjacent sheets defines the part.
