Additive Manufacturing (Page 12)

Errors that occur during large-scale additive manufacturing (AM) builds can be prohibitively expensive for manufacturers. Current in-line inspection methods are inefficient, but damaged and distorted end products waste too much time, material, and money. How can in-process inspection be optimized to improve productivity and ensure quality? EWI investigated this question using the laser-blown powder DED...

Laser powder bed fusion is being used with increasing frequency in manufacturing operations. Some L-PBF materials, however, are still prone to stress and cracking. EWI has created a new “laser stirring” technique that improves results in some of the most common L-PBF alloys including SS316L, Ti-6Al-4V, and Ni718. The results are discussed in Effect of...

In early May, EWI was pleased to take part in COSI’s Big Science Celebration. Held outside the Columbus-based Center of Science and Industry (COSI), the free festival showcased cutting-edge technology and amazing phenomena to promote science literacy and careers in STEM fields to young people. At the EWI booth, our associates were able to share...
