Analysis and research on RP manufacturing precision

摘要

In the rapid prototyping technology, the step effect of the data error and the approximation error of the STL format would affect the machining accuracy.In this paper, we have studied the cause of the error and the method of improving the machining precision. Manufacturing precision of rapid prototyping not only has decisive significance but also influences the stability and service life of parts, so the study on rapid prototyping manufacturing accuracy is very important.
