Three-dimensional printing allows
the creation of solid structures from a digital computer file, potentially
revolutionizing the economics of manufacturing if objects can be printed
remotely in the home or office. The process involves layers of material being
deposited on top of each other in to create free-standing structures from the
bottom up. Blueprints from computer-aided design are sliced into cross-section
for print templates, allowing virtually created objects to be used as models
for “hard copies” made from plastics, metal alloys or other materials.
