Meeting 2026 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2026)
Symposium 2026 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2026)
Presentation Title WAAM development Cell with Adaptive Trajectory Control
Author(s) Dylan S. Lewis, Jared Bradley
On-Site Speaker (Planned) Dylan S. Lewis
Abstract Scope Using a custom three-axis motion platform and a Lincoln SP-140T manual MIG welder, an adaptive WAAM development cell has been realized. The system integrates a multi-axis platform with PLCOpen based controls using Beckhoff’s TwinCAT and a custom Raspberry Pi based Modbus controller to automatically operate the welder. Welder control is integrated into the PLC environment, allowing seamless integration between the MIG torch and the motion platform. The current hardware facilitates an adaptive framework whereby automatic torch height control and in-situ parameter adjustments can be implemented in real time to increase the control of the WAAM process during execution. Initial work has focused on trajectory control strategies to introduce an additional capability for real time path correction during the WAAM process. Current efforts have validated motion functions with integrated welder control for simple trajectories. Future plans are focused on developing a flexible solution with complex trajectories that include on-the-fly path compensation.
