Abstract Scope Polyethylene and boron carbide are widely favored for neutron shielding due to their roles as an effective moderator and absorber, respectively. Additive manufacturing of polyethylene/boron carbide composites offers the potential to create neutron shielding components with tailored geometries and compositions. Fused deposition modeling is a widely accessible additive manufacturing method, making it an attractive fabrication route. In this work, polyethylene filaments with a range of boron carbide loadings were produced, and selected compositions were printed into tensile coupons. The challenges and associated troubleshooting methods that arose during filament fabrication and printing of these composites are outlined.
