Abstract
A melt-processable consumable material configured as a feedstock for use in an additive manufacturing system includes a polymeric matrix comprising one or more polyaryletherketones, wherein the polymeric matrix comprises between about 10 wt % and about 50 wt % of the total weight of the feedstock. The material includes radiation shielding particles dispersed within the polymer matrix wherein the radiation shielding particles comprise between about 50 wt % and less than 90 wt % of the total weight of the feedstock.
