Typical functional materials that are compatible with extrusion-based 3D printing require complex formulation to tune rheological properties. Here, we describe the synthesis and characterization of an alternative material platform comprising single-component solids that undergo fast and reversible shear thinning without solvent or other additives. These materials are suitable for room temperature extrusion under shear from the liquid phase and quickly solidify at room temperature upon exiting the print nozzle. The optional incorporation of other additives enables further control over the mechanical properties of printed structures.
