Sounds like scintering.
You would think so, when they talk about metal powder as the “ink.” But then, it seems that no pressure is involved in the process, only heat from a powerful laser which actually does the printing, after the powder is laid down. Might it not more resemble welding in that case?

On a lighter note (pun intended), there have been articles posted in the past year or so about the economical production of titanium powder. If you are going to the expense of 3-D printing your complex, precision metal part, it would seem that you could find it advantageous to use titanium powder to make it light and strong as well.

The article I’m remembering was about a British company which proposed to use an unconventional (for titanium production) chemical process, and claimed a projected cost per pound competitive with specialty steels. Since titanium is only about 1/3 the density of steel and approximately as strong as steel, that could be a winner.

My Dad never bought another Chevy, until the last car he bought recently, an SUV just before he died.
I got to thinking about this because I saw that station on wagon today, same year, different color.
Right after the rocker arm disaster he bought a Nissan 310 (I think it was numbered). Hatchback but it had a 260Z engine—with fabric fuel injection tubes. The engine caught on fire.
He never had much luck with new cars, except VWs.

This is the process for cheap titanium that you might be thinking of.
