Bre Petis isn't messing around at his first big Consumer Electronics Show press conference. The final of three new MakerBot Replicators the company founder unveiled (more on the other two in a second) boasts a whopping 12-by-12-by-18 print capacity. Volumetrically, that's 2,592 cubic inches--a scale that Petis calls "epic." The printer, dubbed the Replicator Z-18, is an industrial beast; its print area can produce several items simultaneously, or, if you prefer, one gigantic one. Petis actually donned a helmet produced in the Z-18 during his reveal. His enthusiasm was hard to mask. As he unveiled the Z-18, he gushed: "This has been the goal all along."
