MakerBot Replicator Z18
MakerBot's new 3-D printer, dubbed the Replicator Z18, looks like something from a science fiction film. With an 18-inch-high build chamber that also contains the printer's heat, users can generate larger models and 3-D recreations. And the Replicator Z18 also lets you print multiple items at once. The new 3-D printer will be available this spring for $6,499.
