We produce master patern with the rapid prototyping and to research the process which produces the prototype with vacumm casting in study. In order to select the condition where the shrinkage which appears in each process becomes smallest it used the DOE. We could confirm error value using reverse engineering. After getting the P-value with the method due to the Full Factorial Design and the ANOVA 2-way it will be able to judge the factor which gives an effect to error. It applied the error of each process in the masterpattern and improves the Size Precision of vacuum casting prototype the method which it presented.
