A team of ambitious students from the University of Texas at El Paso (UTEP) has claimed the top prize at America Makes’ third annual AM in Steel competition, showcasing their ingenuity with a meticulously designed and 3D printed stainless steel multi-tool. This victory highlights the growing capabilities of additive manufacturing in producing complex, functional metal components for everyday applications, drawing attention to the innovative spirit fostered at UTEP’s W.M. Keck Center for 3D Innovation. The competition, which challenges university teams to engineer visibly 3D printed metal multi-tools, serves as a crucial platform for emerging talent in the additive manufacturing sector, particularly within the critical domain of steel applications.
The winning multi-tool, developed by the UTEP team known as Borderland Steel, is a testament to sophisticated design optimization and advanced manufacturing processes. Utilizing the Laser Powder Bed Fusion (LPBF) technology, the students transformed raw stainless steel 316L into a robust and versatile tool. This achievement not only underscores the technical prowess of the UTEP team but also signifies a broader trend in the industry where additive manufacturing is increasingly recognized for its potential to create high-performance, customized metal parts. The AM in Steel competition, a cornerstone event in the additive manufacturing calendar, has consistently pushed the boundaries of what is possible with steel-based 3D printing, and this year’s edition at RAPID + TCT 2026 in Boston, Massachusetts, proved to be no exception.
From Concept to Competition: The Design and Engineering Journey
The path to victory for Borderland Steel was marked by rigorous design iterations and a deep understanding of additive manufacturing principles. Initially, the team explored numerous design concepts, leveraging in-house PLA desktop 3D printers for rapid prototyping. This iterative process allowed them to quickly test and refine various features, ensuring that the final design would not only be functional but also aesthetically compelling and demonstrably 3D printed. The transition from plastic prototypes to a functional metal tool involved a sophisticated approach to design consolidation. The team strategically reduced the initial 20 designed parts down to approximately five by integrating multiple functionalities into single components. This was achieved through careful consideration of standardizing interfaces, a crucial step in simplifying assembly and ensuring part interchangeability, and by incorporating lattice structures.
The integration of lattice structures was a key innovation, serving a dual purpose: material reduction and optimization of load-bearing capabilities. By strategically placing these internal geometric patterns, the team was able to significantly decrease the amount of material required without compromising the structural integrity of critical load paths. This not only makes the tool lighter and more cost-effective to produce but also showcases a sophisticated understanding of advanced design techniques enabled by additive manufacturing. The team then employed the LPBF process on an EOS M290 system, a leading industrial 3D printer, to fabricate the multi-tool using stainless steel 316L. The choice of stainless steel 316L is significant, as it offers excellent corrosion resistance and mechanical properties, making it suitable for durable, everyday carry (EDC) items.
Following the initial printing, the team engaged in extensive testing and refinement. Multiple iterations of the final design were printed to meticulously improve tolerances and the smooth movement of the tool’s various components. This dedication to precision and functionality is paramount in the creation of multi-tools, where each part must operate reliably and seamlessly. The post-processing stage involved techniques such as electrical discharge machining (EDM) and sandblasting, essential steps to achieve the desired surface finish, dimensional accuracy, and overall quality of the final product. The successful execution of these complex processes culminated in a multi-tool that not only met but exceeded the competition’s stringent requirements.
The Significance of the AM in Steel Competition
America Makes, the National Additive Manufacturing Innovation Institute, plays a pivotal role in advancing additive manufacturing technologies across various industries. The AM in Steel competition, now in its third year, specifically targets the development and application of 3D printed steel components.
