Makino and Fraunhofer ILT Advance Additive Manufacturing with EHLA3D

The collaboration between Makino and the Fraunhofer Institute for Laser Technology ILT has yielded a significant advancement in additive manufacturing: EHLA3D. This process, resulting from the integration of high-speed laser cladding technology with advanced five-axis CNC machinery, is transforming the production, coating, and repair of complex geometries using high-strength materials. EHLA3D not only substantially reduces production times but also significantly extends component lifespans across a diverse range of industries, while simultaneously promoting sustainable practices within the circular economy.

Laser technology continues to be a cornerstone of the manufacturing sector, particularly in additive manufacturing. Recognizing this, the Fraunhofer ILT, a leader in laser technology research, partnered with Makino, a globally renowned Japanese machine tool manufacturer. They aimed to alter the extremely high-speed laser cladding EHLA for use on a five-axis CNC platform. This would involve the development of new kinematics that would allow rapid and dynamic movements of the machining head, facilitating the flexible processing of a wide range of geometrical shapes and materials.

Initially focused on AM, the project soon expanded to include repair applications. “Repairs are extremely exciting,” said Min-Uh Ko, Group Leader for Additive Manufacturing and Repair LMD at Fraunhofer ILT. “Many expensive components must be replaced even for minor defects. A flexible system like the one from Makino, with its rotary and tilting table, offers excellent repair options. This approach reduces costs associated with new production, eliminates transportation and delivery delays, and minimizes downtimes. Moreover, repair is a fundamental aspect of the future circular economy.”
