Abstract

In this work, the binder jetting 3D printing of boron carbide was combined with a subsequent liquid silicon infiltration procedure to produce reaction-bonded boron carbide (RBBC)-based structures. After printing, the samples were isostatically pressed to obtain more homogeneous and denser microstructures while maintaining their complex shapes. The RBBC bodies were successfully fabricated, and the influence of the binder content on the amount of residual silicon was studied. By increasing the binder content from 10 to 22.5 vol.%, the Si content decreased from similar to 28 to similar to 12 vol.%. The mechanical properties dependent on the Si content were additionally investigated. The measured average values for the bending strength (similar to 355 MPa), Young's modulus (similar to 348 GPa), and hardness (similar to 20 GPa) are comparable to those reported in the literature for RBBC-based materials.
