The TVE controller is an embedded industrial closed loop control system designed for FDM 3D printing applications. It is responsible for managing the extrusion axis temperature and position while tracking feedstock volumetric flow throughout the print. TVE provides in-line monitoring of defect points within the print by tracking any voids or deviations in material deposition to within 50 micron. It then injects on-the-fly modifications to the incoming machine code to prevent similar deviations from reoccurring.
The precise position of these defect points are tracked throughout the print to provide a comprehensive report of manufacturing accuracy. This report along with the original part file can be combined to generate a digital 3D map of defect points for simulated FEA analysis and QC.
