96702 - Complex-Shaped Boron Carbide Parts Prepared by Additive Manufacturing Technology
Boron carbide is a refractory material with high hardness, good wear resistance, low density and excellent neutron shielding properties. However, the shaping and sintering of boron carbide parts with complex geometries remains a challenge. This research is focused on the preparation of boron carbide ceramics fabricated by fused filament fabrication. Highly filled composite filaments containing micron-sized boron carbide powder were tested on a FDM printer for manufacturing of complex-shaped B4C ceramic grids with dimensions up to 4 centimeters. The 3D-printed objects were successfully debound and sintered at temperatures up to 2300°C. The samples after sintering had good shape retention and achieved the relative densities higher than 96 %.
