DESCRIPTION
The core of NASA’s EBF3 system uses a wire-feed design to deliver quality parts that are better than cast and similar to wrought materials while minimizing excess material. Multiple wires can be used to introduce multiple materials during part manufacturing, creating new alloys or layered parts. The system costs significantly less to build than others and includes other cutting-edge improvements, enabling companies previously hesitant to enter the market to compete and win in the expanding rapid prototyping and additive manufacturing market.
