"multiple powdered metals deposited with micron-level resolution, laser melted together in single layer during additive deposition... 1 cm tall metal part includes thousands of layers of metal powder, taking a few hours to print... address pores/ cracks in real time viewing digital 3D rendering through CT scans... finished structure complex gyroid shape (which when multi-material can only be created using this method), used in applications such as heat exchangers/ biomedical implants... future: use with other types of metal powders"
