Apparatus for removing excess material and method of operating the same

An apparatus for removing excess material from a cavity of a component, comprising:

• a housing that defines a working space in which the excess material is removable from the cavity, wherein the housing seals the working space against a surrounding environment;
• a platform disposed within the housing and configured to retain the component;
• and
• a drive mechanism configured to rotate the platform independently around two orthogonal spatial directions (X, Y) inside of and relative to the housing, wherein the drive mechanism comprises a motor disposed outside the housing;
• a drive train that connects the motor to the platform;
• and a seal that provides a seal between the housing and the drive train where the drive train passes through the housing.

An apparatus for removing excess material from a cavity of a component, comprising:

• a housing that defines a working space in which the excess material is removable from the cavity and that is at least in fluid communication with an additive manufacturing space when an additive manufacturing process occurs, wherein the housing seals the working space against a surrounding environment;
• a platform disposed within the housing and configured to retain the component;
• and
• a drive mechanism configured to rotate the platform independently around two orthogonal spatial directions (X, Y), wherein the drive mechanism comprises a motor disposed outside the housing and a drive train that connects the motor to the platform, and wherein any electrical components for the drive mechanism are arranged out of the working space.
