Process Improvement for Plasma Transfer Arc Additive Manufacturing

Metal additive manufacturing (MAM) is newly developed manufacturing technology that is faster and more cost-effective compared to traditional methods. Although there are various types for AM, the product quality improvement in plasma transfer arc (PTA) and wire-feed AM processes will be the subject of this project. To achieve this goal, the intern will determine the key parameters of the existing PTA2M and wire-feed machines in InnoTech and then will select appropriate measuring technologies to obtain data from these AM processes. Then, the intern will develop a model for both processes based on either first-principles or system identification strategies. In order to improve the products’ quality, he will develop a process model to estimate the unmeasurable variables and then designs a closed-loop controller. The controller will be designed based on the model and then will be implemented for the actual systems in InnoTech. TO BE CONT’D
