Additive manufacturing (AM) offers the unique capability to fabricate complex geometries and control fundamental material properties during production. AM is particularly promising for manufacturing complex geometries from tungsten and other refractory metals, which are difficult to form using traditional processes. In this study, tungsten lattices of approximately 5x5x5 mm3 were additively manufactured using various laser energy densities. Applications for these tungsten lattices include catalyst beds for monopropellant and green propulsion, insulation, wicking structures, and heat pipes. Lattice strut thickness and pore size were characterized using optical microscopy. Compression tests were performed to determine the effect of laser energy density on lattice strength. Our presentation will discuss the results of these experiments and their implications. This work will help inform the development of tungsten lattices for propulsion systems as well as nuclear systems, where tungsten is already of major interest for fusion systems for plasma facing and high thermal load structures.
