SINTEF’s researchers recently welcomed a visit from our dedicated project officer, Oliver Loran, which had been announced just shortly before his arrival. The timing turned out to be ideal, as we had just completed the installation of the laser positioning system and were conducting tests as part of another project where Oliver also serves as project officer. His presence sparked several engaging discussions and contributed to a positive and collaborative atmosphere. The visit also provided a great opportunity to showcase the promising results from the ALABAMA project, reinforcing the project’s momentum and future potential.

The project team is almost finished testing the dynamic laser positioning system that will make new possibilities possible when it comes to metal microstructures for DED production.

Dr. Nicolas Macallister, a researcher at SINTEF, recently presented a scientific paper exploring the use of multi-laser formations to achieve equiaxed grain structures in Ti-6Al-4V. His work highlights how strategic laser configurations during additive manufacturing can influence solidification dynamics, promoting more uniform and isotropic grain structures. This approach has the potential to significantly enhance the mechanical properties and reliability of titanium components, particularly in aerospace and biomedical applications. The presentation sparked interest in how laser-based process control can be further optimized to tailor microstructures in advanced materials.

The video comparison highlights the potential for increased speed in the DED process.

We continue our search for optimal melt pool behaviour with pulsing laser, beam shaping of laser and different multi laser beam configurations.
