6K Additive has been chosen by the RTX Know-how Analysis Heart (RTRC) and the College of Arizona to take part within the Environmental Additive Analysis for Tomorrow’s Habitat (EARTH) undertaking, beneath the America Makes and Nationwide Heart for Protection Manufacturing and Machining (NCDMM). This initiative focuses on creating sustainable manufacturing strategies for aerospace and protection parts by additive manufacturing.


Advancing Sustainable Manufacturing
The EARTH Undertaking, with a complete funding of $1.2 million from the Workplace of the Beneath Secretary of Protection, seeks to revolutionize the manufacturing of aerospace and protection merchandise. 6K Additive will play a key position by using superior mode-guided course of improvement strategies, cutting-edge laser optics, and extra environment friendly powder feedstock to optimize Ti-6Al-4V—a generally used titanium alloy. The undertaking goals to reinforce deposition charges, enhance feedstock reuse, and improve recyclability, all whereas conducting techno-economic and lifecycle analyses to exhibit the sustainability advantages.
The formidable objectives of the EARTH undertaking embody doubling deposition charges for steel additive manufacturing and lowering feedstock manufacturing vitality by 75% or extra, with out compromising half high quality. Finally, 6K Additive anticipates reaching a 50% total discount in vitality consumption for producing additive parts.
Strategic Collaboration for Protection Manufacturing
Brian Fisher, principal investigator for the Powder and Course of Optimization for Sustainable Additive Manufacturing (POSAM) undertaking at RTX, emphasised the significance of sustainable additive manufacturing processes in creating next-generation aerospace and protection merchandise. Fisher famous, “As a part of this plan, our objective is to introduce lots of of additively manufactured elements to the market over the subsequent a number of years. We chosen 6K Additive due to their technique of changing revert and used powder into high-value, premium powder, which helps us to measure high quality and carbon footprint in the identical undertaking. These advances not solely make additive manufacturing extra sustainable however will drive down prices for manufacturing at scale.”
The POSAM method, mixed with an intensive evaluation of its influence, is anticipated to speed up the adoption of additive manufacturing throughout the Division of Protection (DoD) provide chain. The undertaking goals to exhibit the POSAM method’s effectiveness in growing print charges, lowering vitality consumption, and simplifying complicated provide chains by cost-effective and sustainable processes.
Dedication to Sustainability
6K Additive has earned recognition because the world’s first producer of additive manufactured powder derived from sustainable sources. The corporate gives a spread of powders, together with nickel, titanium, copper, stainless-steel, aluminum alloys, and refractory metals equivalent to tungsten, niobium, and rhenium.
Supported by the UniMelt production-scale microwave plasma course of, 6K’s know-how exactly spheroidizes steel powders whereas sustaining management over the chemistry and porosity of the ultimate product. This course of ensures zero contamination and high-throughput manufacturing, making it a standout within the business.
In accordance with a current Life Cycle Evaluation (LCA) research, 6K’s method can obtain exceptional reductions in vitality utilization and carbon emissions. For its nickel-based alloys, the corporate studies a 90% discount in each vitality consumption and carbon footprint, whereas titanium alloys see a 75% discount. These achievements underscore 6K Additive’s dedication to driving sustainability in additive manufacturing and supporting the broader objectives of the EARTH undertaking.
