The use of Rapid Prototyping techniques for the production of end-use parts is increasing in rapid manufacturing. The mechanical properties of stereolithography parts become the most important factor restricting its wide application. The mechanical properties of stereolithography parts can be not only influenced by the material characteristics, but also by the parameters of manufacturing. The purpose of this study is to investigate the influences of the build orientation on mechanical properties of stereolithography parts. Specimens were fabricated with different build orientations related to layout (flat or on an edge), axis and build angle. Mechanical testing including tensile, compressive and impact tests on stereolithography specimens were conducted. The results indicated that layout had a significant effect on tensile and impact properties, and the axis had no significant effect on tensile and impact properties. Also, build angles play an important factor in the compressive strength. From these results, it appears that related characteristics of layer interface have a significant influence on mechanical properties of stereolithography specimens.
