METHODOLOGY OF RAPID PROTOTYPING

 

The basic methodology for all current rapid prototyping techniques can be summarized as follows:

ü  A CAD model is constructed, and then converted to STL format. The resolution can be set to minimize stair stepping.

ü  The RP machine processes the .STL file by creating sliced layers of the model.

ü  The first layer of the physical model is created. The model is then lowered by the thickness of the next layer, and the process is repeated until completion of the model.

ü  The model and any supports are removed. The surface of the model is then finished and cleaned.
