A desktop 3-D printer builds plastic objects layer by layer

The PrintrBot is designed to introduce 3-D printing to a wider audience. At $550 or $700, depending on the model, the printer is affordable enough to use for home production of many kinds of objects, from cell-phone cases to art pieces. And it's easier to assemble than previous 3-D printers. The inspiration came to creator Brook Drumm when he found it painfully slow to put together an earlier machine with many parts. Kickstarter users then pledged over $830,000 for Drumm to produce kits (see "TR10: Crowdfunding").
Owners can use free software to design objects (or download designs) and then have them printed out in plastic. The plastic, the same type used to make Lego bricks, can be purchased online in the form of spools that feed into the printer. Printing can take minutes to a few hours, depending on the object's size and level of detail.
