One of the early pioneers in desktop 3-D printing, Makerbot, has a robust website about 3-D printing at makerbot.com. Its Replica 2 printer costs about $2,200 and has a 16 cubic-inch build volume.
Makerbot also launched the Thingiverse website where people can download designs for their own 3-D printers. Check out the possibilities at www.thingiverse.com.
Thingiverse is the best way currently to find ready-made designs to print, although people with knowledge of computers can use software like AutoCAD, Blender or Google SketchUp, among others, to design their own objects.
