How can EHLA 3D improve near-net shape deposition over LMD while increasing build rates?

Challenge and Motivation

• Extreme High-Speed LMD (EHLA) is established in coating applications.
• Novel high-speed tripod kinematic system available at Fraunhofer ILT (for feed rates up to 100 m/min)
• Proof-of-concept for defect-free EHLA 3D build up with iron-base and Nickel-base materials successful.

Objective

• Evaluation of EHLA 3D for future application in turbomachinery and as a basis for follow-up projects such as tip repair studies.
• Demonstration of potential benefits of the technology over conventional LMD.
