FWIW it still requires machining for some surfaces. My corporation is 'all in' on a large scale for metal 3d printing... arc, hot laser, etc.. Printed components are then usually machined for attachment points, etc... It's still hugely effective.

Think of it this way:
Old school prototyping:
Make a lost wax mold or sand pattern. Cast with metal. Then clean / machine.
Recent prototyping:
Build a CNC program. Hog the part out of a solid block of metal.

But now, engineering design involves 3D CAD software, so a 3D computer model exists. And can be easily pushed to a 3D printing system. Where you can:
Print directly with the necessary metal
Print to a 'lost wax' plastic mold and then cast it.

3D printing is a significant leap in manufacturing technology. As prices of printers continues to drop and the versatility of materials continues to expand, the technology is going to create a lot of challenges and headaches for businesses and governments. It's going to become easier to copy commercial products for personal use or resale.

Guy I used to work with used to ask me why we couldn't download hardware... he was just trying to be annoying, but yeah, it's gonna be like copying software essentially soon enough.
