Abstract
Additive manufacturing, the process of building components layer by layer offers great flexibility and freedom in design and manufacture. Over the advancements in past a few years, application of this technology has changed from mere prototyping to production of functional components. Though most of the functional components made are parts for the assembly. In this study an attempt has been made to produce a movable component- ball bearing in a single go which otherwise require assembly. A low cost desktop fused deposition modeling (FDM) printer has been utilized to print in multiple materials. The bearing was printed using PLA, ABS and Nylon 66. Surface characterization such as area surface roughness and Shore D hardness of the printed materials have been measured and compared. It was found that FDM has the potential to fabricate complicated movable parts in single step.
