1. A digital manufacturing system for building a three-dimensional object in a layer-by-layer manner, the system comprising:

  • an enclosed, insulated build chamber configured to be purged of oxygen and to maintain one or more temperatures of at least about 350°

    C. in at least a region of deposition;

    a build platform disposed within the build chamber; and

    a deposition head comprising;

    an extrusion line configured to receive a feedstock of a metal-based alloy and to heat the metal-based alloy to a temperature between a solidus temperature and a liquidus temperature of the alloy; and

    an extrusion tip disposed within the build chamber, the deposition head being configured to selectively deposit a flow of the heated metal-based alloy from the extrusion tip onto the build platform in a predetermined pattern.
