The Rapid Tooling Technology is of a wide application foreground. It can be applicable in developing new products, in making wide varieties of elements with small batch, in reducing production cost, in enhancing productivity as well as in realizing Mass Customization. The Rapid Tooling Technology and its process have been introduced, including direct tooling, such as, Selective Laser Sintering (SLS), Three-dimensional Printing (3D-P), Direct-Metal Laser-Sintering (DMLS) and Shape Deposition Manufacturing (SDM), and indirect tooling, such as vulcanized rubber soft tooling, QuickCast, Keltool, Spray-Printing Casting, metal deposition, electroforming etc. Along with the improvement of the Rapid Tooling Technology, the quality of Rapid Tooling will be promoted continually.
