The figure shows the evolution of the microstructure of the melt pool under the influence of the simulated transient temperature field. Nucleated grains are represented in pink-purple plots, while ...

ITHACA, N.Y. -- Just as a snowflake’s intricate structure vanishes when it melts and transforms when it refreezes, the microstructure of metals can change during the 3D printing process, resulting in ...

Additive manufacturing (AM), or 3D printing, is the process by which a solid object is built layer by layer from a digital model. This process provides advantages over traditional manufacturing ...
