I knew ...

.
... it was only a matter of time:

The engine was printed by GPI Prototype and Manufacturing Services using a technique called Direct Metal Laser Sintering (DMLS). In this 3D printing process, a powder of the chromium-cobalt alloy is spread in a thin layer by the printing machine. A computer-controlled laser then fuses the powder into a cross section of the engine component. The machine spreads a second layer of powder and the process repeats until the component is complete.

And if University of California students have access to the technology, it won't be long before every engineering school in the country has it. And then it will make it's way into your garage.
