Unlocking the cause of pitting corrosion in 3D-printed stainless steel

Scientists from Lawrence Livermore National Laboratory (LLNL), Livermore, Calif., delved into the mysterious world of pitting corrosion in additively manufactured (3D-printed) stainless steel 316L in seawater. Stainless steel 316L is a popular choice for marine applications due to its excellent combination of mechanical strength and corrosion resistance. This holds even more true after 3D printing, but even this resilient material isn’t immune to the scourge of pitting corrosion. The LLNL team used transmission electron microscopy and x-ray photoelectron spectroscopy to do a deep-dive microscopy study to figure out what could potentially be responsible for corrosion.

Metal Powder Works and Solvus Global announce strategic alliance

Solvus Global (SG), Leominster, Mass., and Metal Powder Works (MPW), Clinton, Pa., announced a strategic alliance in the development of new materials, a groundbreaking collaboration that will move the needle on the future of powder production for the advanced manufacturing industry. A pivotal aspect of this collaboration is Solvus Global’s acquisition of a Metal Powder Works DirectPowder system, the first unit to be placed outside MPW’s Pittsburgh production facility.

Under the terms of this strategic alliance, Solvus Global and its business unit Powders on Demand will also be the first to join Metal Powder Works’ newly established Developer Network, enabling industry leading startups to combine resources to accelerate the production of new and conventionally challenging powders for the additive manufacturing (AM) industry. With the DirectPowder Unit at their disposal, Solvus Global gains a competitive edge in advanced powder production capabilities for its AM and coating systems. Moreover, being an integral part of Metal Powder Works’ Developer Network will provide Solvus Global with unprecedented access to a wide array of materials not currently available as powder, significantly reducing time and cost to access crucial resources for their innovative projects.

Powders on Demand CEO Brad Richards shares that “We’re excited to lead the way in economic production of powders starting at R&D all the way through commercial scale to enable our public and private sector customers to push the boundaries of AM and coatings.” As Solvus Global Co-Founder & CEO, Aaron Birt describes it, “For instance, there are only 16 approved AMS [Aerospace Material] specifications for powder today while there are more than 2,000 approved AMS specifications for bar stock. AM needs more than 16 alloys to be successful.”

John Barnes Metal Powder Works’ CEO and Founder commented on this exciting development, “We’ve known the people at Solvus Global for a very long time, even before MPW existed. It is crucial for us to help the AM community by making more materials available in powder form, so every business case doesn’t automatically require a change in material. Solvus Global understands the requirements of the various processes for powder, so this is a natural partnership.”

This partnership between Solvus Global and Metal Powder Works is a testament to the shared commitment to pushing the envelope in additive manufacturing and powder production. By harnessing the combined expertise and resources of these industry leaders, the AM industry will have access to limitless possibilities in materials development and manufacturing.
