One of the remarkable examples of hybrid manufacturing is the repair and refurbishment of aircraft engine components. Aircraft engines endure extreme conditions, leading to wear and tear over time. With hybrid additive manufacturing, the damaged parts can be repaired or reinforced using LMD/DED technology. The process involves the following steps:
Step 1: Inspection and Preparation: The engine component is thoroughly inspected to identify areas that require repair or reinforcement. Digital scanning and modeling are used to create a 3D representation of the damaged part.
Step 2: Additive Manufacturing: Using LMD/DED, the damaged areas of the component are precisely repaired by depositing layers of compatible metal powders or wire feedstock. The additive manufacturing process rebuilds the part, ensuring structural integrity and dimensional accuracy.
Step 3: Post-Processing: After additive manufacturing, the part undergoes traditional machining to achieve the desired surface finish, tolerances, and final shape. This step ensures the component meets the required specifications.
Step 4: Quality Control: The repaired component undergoes rigorous testing and inspection to ensure it meets safety and quality standards. This step is critical to ensure the part's reliability and performance in demanding aerospace environments.
