Abstract

Additive manufacturing (AM) processes are using powders with different particle size distributions. However, a significant fraction of metallic powders produced for AM do not have the appropriate particle size distribution to be used in AM processes. Consequently, high-quality powders are out of AM specifications and cannot be used in AM processes. This directly impacts the cost and sustainability of many AM processes. There are opportunities to adapt and develop processes to take advantages of the fine microstructures of these rapidly solidified powders. This presentation provides examples of microstructure and properties of materials produced using AM by-products. The effect of the particle size and consolidation techniques on the properties of the materials is presented and discussed.
