International Classification:

B08B 5/00

US Classification:

134 21, 134 37, 1341042, 134198

Abstract:

A three-dimensional printer uses inkjet-type printheads to rapidly prototype, or print, a three-dimensional model. A powder feeder includes a conveyor system and a metering system to deliver powder to a build area in measured quantities. The powder feeder also includes a vacuum system for loading powder into a feed reservoir or chamber. The vacuum system can also be used to cleanup excess powder. Other powder control features include powder gutters and magnetic powder plows. During printing, a cleaning system operates to remove powder from the printheads. In the event of a printhead or jet failure, the failure can be detected and corrective measures taken automatically. After printing, the model can be depowdered and infiltrated in an enclosure.

International Classification:

B29C041/02

US Classification:

264308000, 425375000

Abstract:

The invention relates to methods and apparatus for fabricating a three-dimensional object from a representation of the object stored in memory. The apparatus includes a stationary build table for receiving successive layers of a build material and at least one movable printhead disposed above the build table. The printhead deposits a binding material in a predetermined pattern on each successive layer of the build material to form the three-dimensional object.
