			=====Description=====

			Most traditional manufacturing processes for single components is based on the removal ''(or subtraction)'' of materials for standrd bvar stockj for example ''(e.g. by drilling, milling or turning on a lathe for example)''. [https://en.wikipedia.org/wiki/3D_printing '''3D Printing'''] is the general term now used for '''Additive Manufacturing ''(AM)''''' which, by contrast, creates objects by a process of fusing together layers of material to build up a 3D product.


			=====Features and Applications=====

			A variety of '''Additive Manufacturing''' techniques have been developed ''(e.g. [https://en.wikipedia.org/wiki/Stereolithography '''Stereolithography'''], [https://en.wikipedia.org/wiki/Direct_metal_laser_sintering '''Direct Metal Laser Sintering ''(DMLS)''''' and even [https://en.wikipedia.org/wiki/Construction_3D_printing '''Construction 3D Printing''' which prints buildings with concrete!)'' but the method most commonly available for schools and hobbyists is based on building up a model from layers of a plastics filament and fusing them together ''(i.e. [https://en.wikipedia.org/wiki/Fused_deposition_modeling '''Fused Deposition Modeling''')'' in which a coil of plastics ‘wire’ is fed through a computer controlled heated nozzle.

			Although school use of 3D printing may be limited to plastics and similar materials, models created in wax can then be used in a '''[[Lost Wax Casting]]''' process to create protoypes in metals such as Aluminium and various Zinc based alloys ''(e.g. Kayem or Mazac)''.
			</span>
			----

			'''[[Injection Moulding]]''' can be less expensive when manufacturing large quantities of plastics products, but Additive Manufacturing is generally more flexible and less expensive when producing relatively small quantities or single protoypes - hence the alternative name of '''Rapid Prototyping'''.
