Does size matter? If you're talking about 3D printing, it used to. Precision printing meant a fixed platen and a limited range of motion for the deposition tool. Less precise printers have been developed to create large objects from clay, concrete, and other building materials, but their extended range of motion comes with drawbacks. One way to overcome this is to print horizontally, as a new tool promises to do (see video). Add lateral movement to the object along with a five-axis arm, and 3D printing just took on a whole new dimension.
