Abstract
In the current study, Direct Metal Laser Sintering and Binder Jetting technologies are employed for direct manufacturing of functionally graded materials. In the past, the additive manufacturing approach has been limited to non- functional parts and their repair. In this project, we are extending this technology to functional graded gears through design decomposition, process modeling and smart machines. This project aims at developing functionally graded material (FGM) manufacturing technologies that enable creation of light weight “Net Shape” parts for power transmissions used in multiple markets such as transportation and power generation. The technologies include design decomposition, additive manufacturing and material characterization. This transformational approach will enable sustainable manufacturing through reduction in material use, processing steps, energy consumption and carbon footprint and create products which have better performance characteristics. Additive manufacturing technology may provide an efficient alternative way to fabricate customized dental implants based on a CAD file with a functionally graded structure that may minimize stress shielding and improve the long-term performance of dental implants.
