Additive manufacturing: 3-D printing beyond plastic

The video explores the evolution of 3D printing from plastic to metal, specifically copper. At Virginia Tech, a team led by Chris Williams is developing a cost-effective method to 3D print complex copper parts using binder jetting. This process involves jetting glue into copper powder and then sintering it in a furnace. While the technology is promising, challenges like air pockets in printed parts remain. The team aims to enhance performance by adding copper nanoparticles. The video envisions a future where additive manufacturing is used for diverse applications, from energy to aerospace.

How does the addition of powdered copper nanoparticles aim to improve the printed parts?
