The transplanting of bone tissue, known as bone grafting, typically involves allograft, which is bone from a deceased donor, or autograft, which comes from the patient's own body. With support from the National Science Foundation, materials scientist Ramille Shah and materials engineer Adam Jakus are working to develop and improve synthetic materials available for bone grafting.

At Virginia Polytechnic Institute and State University, Christopher Williams heads the effort to further advance 3-D printing with copper, a widely used conductor in electronics. Williams is using a process called binder jetting in which an inkjet printer selectively jets glue into a bed of copper powder, layer-by-layer. The printed copper product is then taken to a furnace to fuse the particles together. With support from the National Science Foundation, Williams is addressing a major challenge in the 3-D copper printing process, which is to eliminate the porosity that develops in the part during the process.
