"Three Dimensional Printing (3DP) uses an inkjet head and a water fusible material similar to &amp;ldquo;Plaster of Paris&amp;rdquo;. The machine lays down a thin layer of plaster powder; the inkjet head passes over and sprays tiny drops of water wherever solidification is desired."^^<http://www.w3.org/2001/XMLSchema#string>
