Scaling Up Metals Additive Manufacturing — new paper
By Rebecca Gurk on Tuesday, March 7th, 2017
Additive manufacturing (AM) processes empower manufacturers to build parts that were previously impossible to create using traditional subtractive machining methods. While laser powder bed fusion (L-PBF) is well-developed and offers high levels of accuracy, it is better-suited to small components. As an alternative, laser directed energy deposition (L-DED) combines a laser and a material feed system to build large-scale freeform parts. EWI has aligned with RPM Innovations as a development partner to continue to advance L-DED technology, and has purchased a RPMI 557 system which is now available to EWI’s customers for commercial project work. In addition to supporting customer needs, EWI will be using this system to conduct alloy development work, investigate ways to improve multi-material functionality, and develop methods of increasing overall build efficiency.
