Abstract:

The article describes testing and comparison of strength of 3D printed belt pulley teeth. Toothed belt pulleys are commonly used in wide range of applications, especially powering mechanical equipment in vehicles, or synchronizing rotating assemblies in machines. Often tooth and pulley designs are unique. Commonly used manufacturing method, especially during prototyping phase is 3D printing. Due to complex internal structure of FDM parts, strength of entire part is heavily dependent of 3D printing and slicing parameters. This paper explores this topic by comparing two advanced slicing methods, three material combinations and verifying their results by testing strength of belt pulley tooth samples.
