Abstract
The present disclosure relates to a feedstock for performing additive manufacturing through a heated extrusion print nozzle heated to a working printing temperature. The feedstock may have a glass matrix meltable at the working printing temperature and a reinforcing fiber component. The fiber reinforcing component is disposed within the glass matrix, and selected to be at least one of thermally stable or thermally oxidatively stable at the working printing temperature being used to melt the glass matrix.
