Rapid Prototyping & Tooling
From the technological point of view, prototypes help in verifying the form, fit and function of the part, and as models for assembly checks, stress analysis and wind tunnel testing. Prototypes are also useful as masters for development of tooling.
To reduce product development lead-time and to impart greater flexibility in incorporating client customisations, CMERI has replaced the traditional and wasteful methods of prototype development based, to a large extent, on manual skills.

Rapid Prototyping is a new and powerful tool for rapid product development. A class of technologies has emerged during the last decade by which a CAD file of an object can be converted into a physical model through special material sintering, layering or deposition techniques. The major application of this technology is for early verification of product designs and quick production of prototypes for testing.

Multiple prototypes can now be reproduced more economically by using the RP master as pattern for creating moulded or soft tooling. It has been established that rapid prototyping technology, in conjunction with investment casting, can substantially reduce the cost of producing a prototype metal casting.
