  • Publication number: 20160031157
    Abstract: A feedstock material can be doped with magnetic particles, and an inductive coil can be used to induce an endothermic reaction within the feedstock material, due to the presence of the magnetic particles within the feedstock material, during the creation (or printing) of an object. An inductive coil can also be used to create magnetic fields for manipulating the position and/or orientation of the magnetic particles within the feedstock material before, in situ, and after the AM process. A unique signature can be created by the interaction between a magnetic field and magnetic particles within the feedstock material. DNA can be added to the magnetic particles as a means for providing identification to a manufactured component or for identifying one or more characteristics of the component or portion of the component.

  • Publication number: 20150279525
    Abstract: Chemical or physical markers (i.e., tags) can be embedded in a host resin-based, polymer or thermoplastic matrix used as feedstock for additive manufacturing. These tags can comprise detectable levels of magnetic, electromagnetic, ferromagnetic and other metal alloy materials within the metallic feedstock materials used to create objects via additive manufacturing. Feedstock including tags can be used to manufacture firearms or other objects. The properties of such tags may be used to improve, enhance, or degrade-by-design the properties of the host material. Accordingly, the use of tags can provide traceability, authentication, and other characteristics to a firearm that enable detection and communication between the firearm and sensors.

  • Publication number: 20150165693
    Abstract: Additive manufacturing (AM) materials can be rapidly qualified with dopants that improve accuracy and precision of microstructure. When dopants are sensed by AM supervisory control and data acquisition (SCADA) systems, dopants facilitate targeted guidance. This capability can be used as a 3D stencil when the dopants are relayed as coordinates in 3D space. Dopants can be sensed to provide real time in situ process control, data and feedback about the additive manufacturing process. When an electrostatic or electromagnetic force is applied to the print area, doped materials can be modified to control the melt pool and change various properties of the doped material.
