Engineers are researching novel feedstocks and manufacturing techniques for direct-ink writing. This is one element of a set of additive manufacturing technologies that can fabricate 3D microstructures with unique material properties.

This cellular alumina microlattice architecture exhibits high stiffness and low weight. It was fabricated using Projection Microstereolithography with a feedstock material of photopolymer loaded with alumina nanoparticles. Subsequent thermal post-processing to remove the polymer binder left only the densified alumina.

Conductive carbon and silicone are formulated into an ink and used to print the structure shown. The carbon based ink is able to conduct electrical signals while still having the capability to flow and print using the Direct Ink Write technique. Inset shows spanning of filaments over many times their diameter, while still retaining the shape of the extrusion nozzle.

A steel honeycomb structure embedded in a solid frame can be produced rapidly by LLNL's commercial powder bed metal additive manufacturing capability. Current research focuses on optimization of the manufacturing processes and understanding processing-performance relationships of the materials produced by this promising technology.

A surface enhanced raman spectroscopy (SERS) substrate built with an array of 100 nanometer diameter tapered nanopillars has been shown to increase sensitivity of SERS devices.
