Large-Scale Additive Metals Manufacturing using Non-Gravity Aligned GMAW (LSAMM – NGA)


  • This project is based on extending GMAW LSAMM to non-gravity aligned orientations using a combination of pre-planning strategies and real time sensor control.
  • Two main parts to accomplish this:
    • Development of innovate framework for CAD to Path capable of slicing and planning sections of a part in non-gravity aligned directions. 
    • Development of a real-time control system capable of monitoring the build and correcting for deviations as they occur
