1. A laser sintering system for fabricating three dimensional objects based upon design data and from a sinterable powder, the laser sintering system comprising:

  • a build chamber;

    a part bed defining an area where the sinterable powder is laser sintered, wherein the part bed is adjacent a surface the sinterable powder is deposited upon;

    a hopper for supplying the sinterable powder to the build chamber of the laser sintering system;

    a powder distribution device for distributing the sinterable powder in a layer on the part bed; and

    a chute extending from the hopper toward the surface the sinterable powder is deposited upon, wherein the chute defines a slot, is between the powder distribution device and the part bed, and is movable by movement of the powder distribution device.
