    Abstract: An apparatus for fabricating a three-dimensional object from a representation of the object stored in memory. The apparatus includes an outer drum supported for rotation and an inner drum positioned within the outer drum and supported for rotation therewith. A powder receiving chamber is defined between the outer drum and the inner drum. A build platform is supported for linear movement within the powder receiving chamber from a first position adjacent a first end of the drums to a second position within the powder receiving chamber. The build platform is rotationally fixed relative to at least one of the inner or outer drums such that the build platform rotates with the drums. At least one directed energy source is positioned above the build platform and is configured to apply directed energy to at least a portion of the powder receiving chamber.
