Additive Manufacturing Feedstock Part 2: Developing Strategies for Metal Powder Reuse - Webinar OnDemand

About the Webinar

Part 2 of the Additive Manufacturing (AM) Feedstock covers the concepts and considerations to develop a metal powder re-use strategy.

In industrial AM applications, the consumption of powder is a key contributor to part costs. In addition to the material that is solidified into a part, further material is disturbed and heat-affected by the laser powder bed fusion (LPBF) process. Chemical and particle size distribution changes in the heat-affected material determine whether and how it can be re-used for further builds. Two main methods of powder management are used in production today, an infinite re-use approach with sieving on the machine and regular topping up with new material; and a batch history control approach where powder is re-used multiple times without topping up until the batch is consumed or a specification limit is breached. This investigation finds that there are pros and cons to both powder re-use approaches. The batch history control approach comes with a high level of traceability but a steady degradation of powder quality, whilst an infinite re-use approach will lead to a steady powder quality without the full level of traceability of approach 1.

This OnDemand webinar will take approximately 1 hour to complete.
