It doesn’t seem too long ago that 3D-printers were astounding us by churning out cheeky little trinkets or small replacement parts. But the technology has quickly grown to cater for everything from rapid prototypingto slick-looking commercial products, and a quick snack for astronauts tobizarre models of unborn babies. Jim Smith of Grass Roots Engineering has been designing and building his own home-based, large-scale 3D printer since 2008, and the latest modification recently spent over 40 days producing 28 colorful ABS plastic sections that were bolted together to create a 16.7 ft-long kayak.
