I wouldn't hold my breath on this.It'll be interesting if SLS printing gets to accessible consumer grade levels. I wanna shoot toxic aluminum dust with lasers and make guns in my shed
Actually, metal powders are toxic, so maybe you should hold your breath.
The machines I've seen flow Argon thru the chamber to keep vaporized powder from covering everything in the chamber. Also I think the inert gas also serves to prevent metal powder fires/explosions. And when all said and done, parts often have to be 'baked' to relieve internal stresses in between layers; ie. Hot laser melting substrate on top of Completed cold layers.
Also, the surface finish you get from boiling metal is poopoo, often needs finish machining
I'd put my bets on some kind of novel breakthrough on an existing subtractive technology. I seem to recall a guy on YouTube who made an EDM (electro discharge machining) rig out of an ender3
