4. A corrective action method for a composite-based additive manufacturing (CBAM) process comprising:
using camera monitors at one or more of the platen, conveyor or stacker locations within a CBAM system to make an automatic determination whether a page traveling through the CBAM system is within tolerance;
if the determination is that the page is not within tolerance, performing corrective action comprising:
(1) Determining if automated correction is possible, and if not, pausing a print job and notifying an operator while waiting for the operator to indicate if an issue is resolved;
(2) If automated correction is possible, performing the automated correction, performing tests to determine if the issue is corrected, clearing the affected sheet from the CBAM system, and restarting printing.
