The Analysis of Key Influence Factors and Application Countermeasures on Quality of FDM Prototype Model

This paper presents a study on the machining quality of prototype model, and points out its important influencing factors including shaping room temperature, shrinkage ratio of material and wet condition of support material and so on. The prototype model was processed by FDM 3000 rapid prototyping machine made by Stratasys, Inc. There are some concrete problems including inappropriate placement orientation, oversize of prototype, and high efficiency of multi-parts manufacture in practice. At the same time, practical methods were given.
