Wire and Arc Additive Manufacturing : Pre printing strategy for torque arm

Wire and Arc Additive Manufacturing (WAAM) is a novel Additive manufacturing method. It is a high deposition rate process which can be suitable for producing low to medium quantities of medium to large sized components. Because it is such a novel method, there are still somechallenges to solve for the method to be useful. This project have been focusing on how to dealwith these challenges and how to manufacture a torque arm with WAAM. This includes the process on how to go from a CAD model to a printed product. Tests have been done during the project parallel with the design of the torque arm. The design have been modied according to the results from the tests. The result of the project was a more specic description how the softwares can be used to optimizethe process for a successful print. The used slicing software, Simplify3D, have some limitations and other options should be considered. Some limitations for the part design have been identied and some known challenges have been solved. The torque arm was successfully printed but with more time and refinement, the added offset could be reduced. The process was time consuming and needs to be more automated in the future. Some proposals on what should be further tested and evaluated is also stated in this report
