A Time, Cost and Accuracy Comparison of Soft Tooling for Investment Casting Produced Using Stereolithography Techniques
MetadataShow full item record
Investment casting is increasingly widely used in the production ofmetal prototypes in conjunction with rapid prototyping (RP) technologies. Some types ofRP models can be used directly as sacrificial patterns in the casting process, but this can prove costly and time consuming where a number of castings are required. Soft tooling such as resin tooling and silicon rubber tooling are used to produce a number of wax patterns for subsequent casting, using an RP model as the master. Stereolithography faced tools are starting to be used as in some circumstances they can offer time savings over other soft tooling methods. This paper aims to compare the costs and times taken to produce wax patterns for use in investment casting using the different soft tooling techniques and QuickCastTM build style for use as a casting pattern.
