Comparative Analysis of Different Methods of Rapid Tooling


Article Preview

The purpose of this experiment was to compare different techniques that help improve conventional tooling. The methods investigated were chosen from both the methods of Rapid Tooling: direct and indirect. Six different methods were selected including, Sand Casting, Investment Casting, Fused Deposition Modeling (FDM), Direct Composite Manufacturing (DCM), Selective Laser Sintering (SLS), and Stereolithography (SLA). Several industrial corporations were contacted to help complete all six tests. Five parameters were selected for the comparison of these samples: dimensional accuracy, tensile strength, surface roughness, time for completion, and weight. Through comparison the strengths and weaknesses of each method was determined. It was found that different methods did better in various parameters. However, Selective Laser Sintering (SLS) seemed to have the best overall performance.
