Introduction to Rapid Prototyping




Manual prototyping by a skilled craftsman has been age-old practice for many centuries. Second phase of prototyping started around mid-1970s, when a soft prototype model by 3D curves and surfaces could be stressed in virtual environment, simulated and tested with exact material and other prorperties.




Third and the latest trend of prototyping, i.e., Rapid Prototyping (RP) by layer-by-layer material deposition, started during early 1980s with the enormous growth in Computer Aided Design and Manufacturing (CAD/CAM) technologies when almost unambiguous solid models with knitted information of edges and surfaces could define a product and also manufacture it by CNC machining.
