Project description
The lifespan of a product is often limited by the availability and cost of replacement parts. Cost-effectively generating replacement components can significantly extend the operational life of these devices. Many replacement parts are internally simple but geometrically complex, making them ideal candidates for 3D printing. However, challenges arise when the materials available for 3D printing differ from those used in the original manufacturing process. This necessitates detailed analysis to ensure sufficient durability and performance, especially for parts exposed to significant loads or harsh environmental conditions. Additionally, older devices often lack the necessary 3D files for replication, requiring the regeneration of files from the original parts. Additive manufacturing, combined with 3D scanning, offers tremendous potential for producing replacement or upgraded components, even when original design files are unavailable. A specific application of this approach is the production of marine propellers, which feature intricate geometries difficult to specify numerically. These components are prone to damage from impacts with marine debris during normal operation, necessitating frequent replacement or repair. This project focuses on evaluating and implementing the steps required to produce a functionally equivalent replacement propeller based on the original. The process involves performing a 3D scan, preparing the scan data for printing, selecting and evaluating suitable materials, and developing printing approaches. The replacement propeller will undergo deformation analysis, thrust performance testing, and environmental robustness assessments to ensure it meets functional requirements.
Note: You need to register interest in projects from different supervisors (not a number of projects with the one supervisor).
You must also contact each supervisor directly to discuss both the project details and your suitability to undertake the project.
