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.

Three-dimensional printer

The invention relates to apparatus and methods for producing three-dimensional objects and auxiliary systems used in conjunction with the aforementioned apparatus and methods. The apparatus and methods involve 3D printing and servicing of the equipment used in the associated 3D printer.

Apparatus and methods for servicing 3D printers

A three-dimensional printer includes multiple printheads for printing binder and/or colorant onto a bed of build material in a build chamber. The printheads can be mounted on a gantry that is designed for reciprocal displacement across a build chamber along a slow axis. The printheads, in turn, can reciprocally move across the gantry on a fast axis to enable displacement of the printheads along both the fast and slow axes so that the printheads can deposit binder liquid and/or colorant across the surface of a bed of build material in the build chamber.
