Recently, giant 3D printers in China were able to produce ten houses in just one day, and at a cost of less than $5,000 per house, proving just how time and cost efficient 3D printing can be.

So how does 3D printing work, and why is it so efficient? How can 3D Printing enter the consumer market just as it has, for example, the Dental Market? If a 3D Printer can print teeth, can it print toys?
