Abstract
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 continuously printing radially about a circular and/or rotating build table using multiple printheads. The apparatus and methods also include optionally using multiple build tables. The auxiliary systems relate to build material supply printhead cleaning diagnostics, and monitoring operation of the apparatus.
Claims26
An apparatus for fabricating a three-dimensional object from a representation of the object stored in memory, the apparatus comprising:
- a rotary annular build drum for receiving successive layers of a build material therein;
- and
- an array of at least one printhead disposed above the annular build drum, wherein the at least one printhead is configured for selectively dispensing droplets of a liquid binder onto the build material.
An apparatus for fabricating a three-dimensional object from a representation of the object stored in memory, the apparatus comprising:

- and
- an array of at least one printhead disposed above the annular build and movable relative to the annular build drum wherein the at least one printhead is configured for selectively dispensing droplets of a liquid binder onto the build material.
