In a few years, new 3-D printers could make it possible to print out solid objects just like you print out your homework assignments today.
Imagine downloading three-dimensional plans from the Internet, pressing print on your home printer, and having a new fork or toothbrush in just a few hours. The technology could even be used to make action figures from your favorite video game characters.
These 3-D printers have been around for about 10 years, but they could cost up to $100,000. A that price, only colleges and engineering companies could afford them. Now, some companies are working on versions that will be cheap enough to be used at your neighborhood copy shop, or even in your home.
