Binder jetting is unique among additive manufacturing processes due to its material flexibility and high throughput. Traditionally, binder jetting of metals has been utilized for shaping a stainless steel powder and infiltrating with bronze to create a fully dense metal. Although this material system is suitable for a variety of applications –pump impellers, rubber mold tooling, and others – additional material systems must be developed for full adoption into the manufacturing industry. The current approach by researchers is to explore densification of single alloy materials shaped via binder jetting; however, the low-hanging fruit in terms of high-utility, full dense materials for binder jetting are hybrid metal systems. This paper presents work toward creating a metal-metal hybrid consisting of a printed tungsten infiltrated with steel. This material combination offers toughness and wearability suitable for tooling applications. The process for net shaping this material will be presented along with mechanical property data.
