Remote monitoring and control of a three-dimensional object in a fabrication apparatus

A three-dimensional object fabrication apparatus comprising:

• a housing enclosing a work area;
• an interface in the housing to receive digital data defining a geometry for a three-dimensional object to be fabricated;
• a fabrication mechanism to form a portion of the object by addition of a material, substantially consistent with the digital data for a corresponding portion of the geometry;
• and
• a subtractive head to remove material to the increase the consistency between the portion of the object and the digital data for the corresponding portion of the geometry.

A three-dimensional object fabrication apparatus comprising:

• a housing enclosing a work area;
• an interface in the housing to receive digital data defining a geometry for a three-dimensional object to be fabricated;
• a fabrication mechanism to form a portion of the object by addition of material, substantially consistent with the digital data for a corresponding portion of the geometry;
• a rotary table to hold the object during fabrication;
• and
• an axis to traverse from a perimeter of the rotary table to at least a center of rotation to allow access to alter the shape of the object.

A three-dimensional object fabrication apparatus comprising:

• a housing enclosing a work area;
• an interface in the housing to receive digital data defining a geometry for a three-dimensional object to be fabricated;
• a fabrication mechanism to form a portion of the object by addition of material in layers, substantially consistent with the digital data for a corresponding portion of the geometry;
• wherein the side surface of a single layer is actively shaped substantially following the corresponding portion of the geometry.
