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.

Methods for additive manufacturing of radiation shielding parts

Disclosed are three-dimensional parts, such as orthotics and prosthetics, having sinusoidal wave pattern infill structures first and second boundary walls. Also disclosed are printers or systems configured to manufacture such parts, as well as methods of manufacturing such parts. The sinusoidal wave pattern infill structures are formed between, and normal to, the first and second boundary walls and are configured to provide locally tunable structural properties in different regions of the part.
