Introduction to 3D Printing by Greg Emerson
It's not often that a revolution comes along to change everything, but like the Internet changed the way we communicate and share information, 3D printing will fundamentally change the way we make things.
Known also as "additive manufacturing" (because it builds objects by adding materials layer by layer in cross sections), the technology is growing rapidly in ways that promise to replace the almost 100-year-old mass-production model that defined the industrial revolution.
And instead of just padding the bank accounts of huge corporations and their shareholders (which it will do as well), the people set to benefit the most are consumers, small businesses and communities that will now be able to make and customize just about anything imaginable for local markets.
