Leading the development of manufacturing metals parts with metal powders has been the aerospace industry, which expects to consume about $150 million in 3D metal powders by 2019. Aerospace has been the pioneer for metal additive manufacturing in high-value applications. The supply chain for metal powders for additive manufacturing is potentially robust, as production processes for metal powders have been utilized for decades, with hundreds of thousands of tons of powder being supplied to manufacturers across the globe each year. The future is very promising for metal powders for use in 3D printing, but, as wide investment in R&D for self-monitoring and reporting in metal 3D printers is taking place. This will lead to quicker qualification of metal parts printed via additive manufacturing in high-value applications.
