摘要： A three-dimensional article making apparatus includes a build material dispenser for dispensing build material based upon the article defining data, and a deviation sensor for sensing a deviation during construction of the article. The apparatus may operate the build material dispensing means to adjust or recover for a sensed deviation during construction of the article. A portion of dispensed build material may be removed responsive to a sensed deviation. In addition, the deviation sensor may be operated a plurality of times during construction of the article, and a portion of dispensed build material may be removed down to a previous desired article portion. The deviation sensor may be provided by article formation deviation sensor, a build material dispenser sensor, an article defining data deviation sensor, and/or a build rate deviation sensor. The article deviation sensor may cooperate with a heated electrically conductive body used to periodically dimensionally normalize the article. Method aspects of the invention are also disclosed.

摘要： An apparatus for making a three-dimensional article based upon article defining data may be used to make a mold for the article and molding the article from the mold. Alternately, the apparatus may be used to make articles having filled or solid portions. The apparatus preferably includes a base, a processor for defining a mold skin for producing a mold for the three-dimensional article, and a build material dispenser for dispensing build material responsive to the processor to construct the mold skin extending outwardly from the base and defining at least one cavity. Solidifiable fill material is introduced into the cavity to form solid mold portions. The solid mold portions may be separated from the mold skin, and injection molding, for example, used to mold the three-dimensional article. The base preferably includes a thin plastic layer which is penetrable to permit introduction of the solidifiable fill material into the cavity.

摘要： 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. The first and second positioners may be used for selectively positioning the build material reservoir adjacent the solid build material supply to replenish build material within the build material reservoir. In addition, a build material level sensor may be provided for initiating replenishment of the build material reservoir responsive to a low level of build material. Related methods are also disclosed.
