*Notes

A 3-D printer is a machine that can produce three dimensional solid objects. The printing process is similar to the process of making a multi-layer cake: The printer produces layer after layer of the model object until the final product is formed. Some companies are using this printer to produce a prototype of products (e.g. shoes) and make changes before manufacturing the ‘real’ products. The common material used in a 3-D printer is thermoplastic (a kind of flexible plastic that becomes hard when it cools).
