THE NEXT BIG THING?

A Dutch firm's 3-D device can make molded plastic objects the size of a small room.
The KamerMaker (Dutch for "room maker") is being tested on smaller objects but eventually should be able to turn recycled waste plastic into furniture, small boats or anything else approaching 600 cubic feet. Its creators, working at Amsterdam-based DUS Architecture, hope such large 3-D printers will let disaster-stricken communities put out temporary housing made from recycled plastic.
