AT&T is now selling Cube 2 3D printers in its online store

As 3D printers continue to become more popular, more and more retail outlets are beginning to carry the devices. Staples became the first major retailer to carry 3D Systems’ Cube 3D printer in retail stores, and Office Depot offers in-store demonstrations for those who want to buy the 3D printer from their Web site. Now a wireless carrier is getting in on the action.
