Reticulated titanium scrolls are produced by printing titanium hydride lattices composed of two orthogonal layers of ink filaments, which are then rolled into cylinders and reduced to titanium upon partial vacuum sintering. The resulting three‐dimensional titanium scrolls contain a hierarchical pore size distribution composed of macroporosity between patterned filaments and micropores within each filament. These reticulated architectures exhibit an attractive combination of stiffness, strength, and ductility when tested in uniaxial compression.
