  • Patent number: 5784279
    Abstract: A three-dimensional article making apparatus includes a first positioner for positioning a build material jetting head along a first direction, a second positioner for positioning the first positioner along a second direction so that the jetting head is effectively positionable along the second direction as well, and a build material reservoir being mounted on the first positioner so that a flexible connecting tube need only flex to accommodate positioning of jetting head along the first direction but not along the second direction. The jetting head may be a piezoelectric jet which operates by forming a negative meniscus at an orifice of jet between droplets. Accordingly, the build material reservoir may be mounted vertically relative to the piezoelectric jet to form the negative meniscus by negative head pressure. The apparatus preferably includes a solid build material supply mounted on an apparatus frame for storing build material in solid form.
