Abstract Scope |
Repairing damaged components is a critical application for additive manufacturing, particularly for directed energy deposition (DED), where new layers of materials are deposited in the damaged areas to restore its original shape. Reconstructing the damaged volume is essential to provide the geometry for printing. In this investigation, voxel-based damage reconstruction methodology was introduced. The models of nominal and damaged parts were transformed into voxel representation, after which boolean operation was performed to extract the damage. This approach was evaluated in terms of accuracy of the reconstructed damage. Case studies were then conducted to exhibit the application of this approach for repair. For this, the nominal and damaged models were obtained by 3D scanning, and they were utilized for processing. The acquired damage was sliced into layers to generate repair toolpath. Subsequently, materials were deposited back on the worn area by DED experiments, illustrating the functionality of the proposed methodology. |
