Doesn't koenigsegg use 3D printed turbo for their latest cars? (Low production volume+design complexity)

Shapeways allows you to print directly in some metal, (for other they print a wax model then die cast it, or for stainless steel they glue it together then substitute the glue for bronze if i remember, it's quite strong!).

I tried both stainless and bronze, worked perfectly.
