Research Thrust Areas

Diagram that states "Science and Engineering in AM" with different types of AMAdditive manufacturing may sound complicated, but the theory isn't. Instead of building a sandcastle by subtracting sand away from a pile until the structure appears, imagine adding sand beginning at the bottom and moving up layer by layer until a castle is built. In the actual application of additive manufacturing, the grains of sand would be placed one at a time in a specific order pre-determined by enhanced computer design.
