More Information
Summary:Methods and systems for diagnosing and controlling material deposition during a material extrusion 3D printing process. A current sensor can measure a current signal consumed by a material feed motor. The current signal can be analyzed in the time domain and frequency domain to detect material deposition characteristics and prescribe process parameter changes.
