About

Kevin Hoefer is a researcher specializing in arc-based additive manufacturing, with a particular focus on metal deposition technologies for structural components. His work sits at the intersection of advanced manufacturing processes and materials science, exploring innovative approaches to producing complex metallic parts with greater efficiency than traditional methods. Hoefer's most influential contribution is his 2017 comparative study of wire- and powder-based arc additive manufacturing of steel components, which has garnered 55 citations and established him as a credible voice in the field. This foundational work helped clarify the practical tradeoffs between competing feedstock approaches, informing industrial and academic decision-making in the space. Building on this, Hoefer has pursued titanium manufacturing as a dedicated research thread, investigating 3D Plasma Metal Deposition (3DPMD) as a viable alternative to laser powder bed fusion. His 2018 paper on titanium additive manufacturing highlighted key advantages in material utilization and geometric freedom, while his 2021 multi-material study pushed boundaries further by demonstrating functionally graded titanium-tungsten carbide components — a significant step toward tailored, application-specific material properties. His body of work reflects a consistent drive to expand the capabilities and accessibility of arc-based metal additive manufacturing.
