Over the past three years, the additive manufacturing market is estimated to have grown by almost 20% to about $1.2 billion. It is already being used to make prosthetic
devices, architectural components, parts for automobiles or airplanes, jewelry, textiles, sports equipment, and even specialty foods. Over time, additive manufacturing will
become cheaper and more precise and will enable construction down to a nano-scale, atom by atom. But these changes are only the beginning.
