- culturestate 6y agoPowdered metal parts are everywhere today, but it's not really an additive process - you pour a bunch of powder into a mold, compact it, and then bake it. PM parts are also porous and fairly weak (in some dimensions) relative to machined counterparts, so you don't typically see them in critical applications.
