This special issue advances interdisciplinary research at the convergence of computational engineering and materials science for the additive manufacturing of objects with tailored properties. The SI focuses on methods for tailoring and creating functionally graded composite materials and structures with advanced AM techniques. The scope includes research across AM materials, processes, and characterization:

• Novel approaches for creating materials with enhanced, tailored, or graded properties via AM.
• 4D printing, multi-material 3D printing, novel feedstock development (solid, liquid, powders, etc.), in-situ synthesis and alloying techniques.
• Computational engineering, design, and simulation of bio-inspired alloys and structures, processes, and material behavior.
• Process development for graded complex geometries (lattice structures, metamaterials, TPMS, etc.).
