Methods and systems for repairing powder containment structures

An additive manufacturing system comprising:

• a consolidation device;
• a powder bed;
• and
• a controller comprising a processing device and a memory device, said controller configured to:
• generate a supplemental scan path based on a location of a detected defect in a structure formed using an additive manufacturing process, the structure including a first surface that faces a powder containing region and a second surface that faces a substantially powder free region;
• and
• control said consolidation device, based on the supplemental scan path, to remedy the defect.

A controller for controlling an additive manufacturing system comprising:

• a memory device;
• a user input interface;
• and
• a processing device, said processing device configured to:
• generate a supplemental scan path based on a location of a detected defect in a structure formed using an additive manufacturing process, the structure including a first surface that faces a powder containing region and a second surface that faces a substantially powder free region;
• and
• control a consolidation device, based on the supplemental scan path, to remedy said defect.
