The oil and gas industry already provides much of the off the shelf technology used by CWE, perhaps they will provide a shortcut to 3D printed technology as well.

"3D printing allows complex shapes to be built up in layers from particles of plastics or metal, enabling engineers to realize designs impossible to mass-manufacture before.

GE Oil and Gas, one of GE's fastest growing divisions, is investing $100 million over the next two years on technology development with a “significant portion” going on 3D printing, also known as additive manufacturing. The division has installed dozens of plastic and metal 3D printers across its businesses."
