How metal can now be 3D printed (additive manufacturing?) like you can with by dripping plastic layer by layer and it dries up over time?

Here’s a video from GE demonstrating one method. Sintering is one already method of processing metals that don’t machine or melt well enough. The short version is you have a powder and heat it so that it fuses together. The 3D print is using a laser to melt just the slice, then laying down more powder.
