Automated In-Process Quality Control of Recycled Filament Production and FDM Printers

Cornerstone Research Group Inc.rsquo;s (CRG) demonstrated expertise in polymer AM materials development, systems engineering, and feedstock recycling for ISRU offers NASA the opportunity to obtain AM process monitoring and control systems for online quality control of feedstock production and printed parts. CRGrsquo;s proposed approach applies sensors, hardware, and software algorithms to monitor and adjust feedstock production AND printing processes in real time as well as certify feedstock and print quality. Hardware and software developed on this program by CRG will be integrated into future platforms initially targeting the ERASMUS Recycler sub-module already under development to support NASArsquo;s ISM. Integration of CRGrsquo;s in-situ automated quality control technology into a duplicate of the ERASMUS Recycler submodule will occur during this Phase II effort.
