Yep, I hear ya but I believe that they are still perfecting the recipe

Last week, GE opened a new industrial-scale 3D-printing center in Pittsburgh, Pennsylvania. It will work closely with Vinciquerra’s team, test their findings and get GE factories quickly cooking with additive.
His team has already started testing and tabling the powdered materials used in additive manufacturing and their properties. “We want to know how they come together, how they affect each other and what machines and processes are best suited for them,” Vinciquerra says. “It’s just like a gourmet recipe. We need to know how our ingredients are going to react in a mixer or an oven. And what changes can we make to those ingredients, the mixer or the oven to produce a more palatable dish?”
