Video: Additive manufacturing—3-D printing beyond plastic

Tuesday, July 28, 2015 - 06:30 in Physics & Chemistry

At Virginia Polytechnic Institute and State University (VT), Christopher Williams heads the effort to further advance 3-D printing—known among engineers as additive manufacturing—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
