GA-ASI Leads $5.5M Program to Standardize 3D Printing Alloys

GA-ASI Spearheads $5.5M Initiative for 3D Printing Alloy Qualification \nIn a significant move, America Makes has selected General Atomics Aeronautical Systems, Inc. (GA-ASI) to lead a $5.5 million program aimed at developing material allowables for a scandium-aluminum alloy across three classes of laser powder bed fusion (LPBF) 3D printers. Funded by the Office of the Under Secretary of War’s Manufacturing Technology Office (OSD ManTech), this initiative, known as Generation Of Technical-data for High-strength Aluminum Alloy Material (GOTHAAM), was announced earlier this year.\n \\[The funding, while modest by defense standards, targets a critical issue: the qualification of metal alloys for additive manufacturing. Traditionally, qualifying a metal alloy for 3D printing has been tightly linked to specific machines, process parameters, and production sites. Any change in these variables often necessitates additional testing or requalification, which can be both time-consuming and costly.]\\\n \\[John Martin, Additive Manufacturing Research Director at America Makes, emphasized the importance of this project, stating that qualifying advanced AM materials to deliver robust, corrosion-resistant components for critical defense applications directly strengthens the defense industrial base.]\\\n \\[### What This Means for ASEAN Factories \\For factories in Thailand, Vietnam, Indonesia, and Malaysia, this development could have far-reaching implications. The ability to qualify a single alloy across multiple 3D printer models and manufacturers would significantly reduce the complexity and cost of adopting additive manufacturing. This standardization could enable more seamless integration of 3D printing into existing production lines, leading to increased efficiency and flexibility. For example, a factory in Thailand that currently uses an EOS M290 could potentially switch to a Nikon SLM 280 without the need for extensive requalification, saving both time and resources.]\\\n \\[### Cross-Platform Qualification \\The technical objective of GOTHAAM is to generate qualification data for a 7075-T73-equivalent alloy, specifically Scalmalloy, that can be established across small, medium, and large-format LPBF systems. The project includes six 3D printer models from three different OEMs: EOS, Nikon, and GE/Colibrium Additive. The team assembled by GA-ASI includes 17 partners spanning the entire additive supply chain, from raw material suppliers to software providers.]\\\n \\[One key partner is Dyndrite, which will apply its SASSQUATCH methodology to harmonize LPBF processes across different 3D printers. This approach aims to give engineers programmatic control over variables such as laser assignment, toolpath zoning, and gas flow, which are typically controlled through machine-specific software and settings.]\\\n \\[### Testing the Limits of Qualification \\While the premise of cross-platform qualification has not yet been proven at scale, it addresses one of the significant bottlenecks in additive manufacturing. Differences between machines, process conditions, and manufacturing environments can affect process repeatability, making qualification and validation more challenging when production is transferred or scaled.]\\\n \\[GOTHAAM is part of a broader effort by America Makes to address these challenges. Other related programs include AIM-4AM, which uses AI and physics-based modeling to reduce the volume of physical testing needed for material allowables, and Delta Qual 2.0, which focuses on qualifying ranges of AM process parameters. Together, these initiatives aim to create a future qualification framework with fewer physical tests, validated process windows, and material data that can travel across different machine classes.]\\\n \\[### Concrete Takeaway for Factory Buyers \\For factory buyers in ASEAN, the success of GOTHAAM and related programs could mean a more streamlined and cost-effective adoption of 3D printing. By reducing the need for extensive requalification, these efforts could make it easier for factories to integrate 3D printing into their operations, leading to greater innovation and competitiveness. As the technology matures, staying informed about these developments will be crucial for any factory looking to leverage the full potential of additive manufacturing.]\\\n
