What 3D Printing Can & Can't Do

Good story.

The closing paragraph summed it up...

The most critical skill needed for 3D printing, however, is just good knowledge of manufacturing design, experts agreed. "With 3D printing, you can print virtually any geometry that you can design," said Cobb of Stratsys. "But you have to have good design skills. And not everyone has that."

Seems like there's plenty of scope for halfwits to still have a go and fail.
