# Closed-Loop Metal Powder Solutions Continuum Powders Introduced Its Greyhound Melt-to-Powder Tech By Adam Harrie | Written with AI assistance | Published 2026-08-28 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/Continuum-Powders References: [3dprint](https://3dprint.com/330659/can-metal-recycling-help-scale-additive-manufacturing-continuum-and-am-research-white-paper-takes-a-look/) & [continuumpowders](https://www.continuumpowders.com/melt-to-powder-the-science-behind-continuum-powders-sustainable-metal-production/)  Continuum Powders highlighted its Greyhound Melt-to-Powder (M2P) technology for converting metal feedstock and scrap into spherical powder for [metal additive manufacturing](https://www.trendhunter.com/trends/Additive-manufacturing-scaling), supporting closed-loop reuse of high-value alloys. The approach was featured in a new white paper from Continuum and Additive Manufacturing Research, Metal AM at Scale: The Closed-Loop Materials Era, which examined recycling’s role in scaling AM supply chains. The white paper and a companion webinar explored cost efficiency, supply autonomy and technical pathways for recycled powder, including Continuum’s work with Siemens Energy and research on binder-jetted MAR-M 247LC superalloy. The discussion also covered mechanical testing and qualification steps needed for critical applications. For manufacturers, local recycling can reduce material cost exposure, improve supply resilience and strengthen access to strategic alloys. As metal AM moves toward [higher-volume production](https://www.trendhunter.com/trends/Scalable-Metal-3D-Printing), [closed-loop powder supply](https://www.trendhunter.com/trends/3D-printed-recycled-construction-materials) could become an increasingly important lever for scale.
