Best practice procedure for the use of rapid prototyping models for precision foundry applications

The introduction of rapid prototype models in precision foundry applications is seen as an excellent way to decrease the time to market new products, reduce the tests needed to optimise the feeding and filling systems of the components and production of low series and prototypes. Models can be obtained that are compatible with the precision foundry operations in very short times and competitive prices.

There are presently many technologies that work with different materials and provide models with different technical features. These models can substitute wax models and even though their behaviour is somehow similar to the wax, there are always important aspects that must be taken into account. (The burning out cycles, tolerances obtained, surface roughness, the ash content etc.)

The best practice procedure is a document that describes all the parameters that must be taken into account when working with rapid prototyping models in order to obtain a final good casting. Aspects such as the different burning cycles needed for each RP technology/material, cleaning and handling operations, surface improvement, waste recycling etc will be contemplated in order to avoid the most usual problems when working with rapid prototypes. Case studies are included that provide examples of potential applications.
