Additive manufacturing continues to redefine the boundaries of modern engineering, enabling the creation of intricate geometries and customized components with unmatched precision. A recent trial conducted by the Welding and Laser Group at the Technion – Israel Institute of Technology, one of the first research groups worldwide to utilize dynamic beam laser technology for Directed Energy Deposition (DED) with wire, has demonstrated the immense potential of this approach.
The trial showcased the fabrication of a complex 8 cm tall tube using magnesium AZ-31 alloy, a material known for its lightweight properties and excellent strength-to-weight ratio. Leveraging dynamic beam shaping technology, the team produced a component with a refined and homogeneous dendritic structure—a feat that exemplifies the precision and versatility of this advanced laser technology.
In just a short time, the component was fabricated with consistent quality throughout its structure, highlighting dynamic beam shaping's ability to optimize energy distribution, reduce defects, and enhance material properties.

Unlocking New Possibilities for DED Wire Processes
Dynamic beam shaping technology plays a pivotal role in unlocking the potential of magnesium alloys like AZ-31. Unlike static beams, dynamic beam shaping allows real-time modulation of the laser’s properties to suit the material's specific needs. This approach minimizes common issues such as porosity and cracking, which are prevalent in traditional manufacturing processes, and results in superior mechanical and structural properties.
This effort by the Technion demonstrates the potential for expanding DED wire processes. The team plans to further explore how different power distributions enabled by dynamic beam shaping can lead to additional breakthroughs in additive manufacturing. Future investigations aim to develop new applications across industries.
