Additive manufacturing of hard TiC-based cermets typically employs a high-energy beam as the energy source but suffers from high residual stress and microcracks. Herein, we propose an economical additive-manufacturing process for TiC-based cermets using powder extrusion printing (PEP) combined with pressureless sintering, which overcomes inadequacies such as extensive residual stress and microcracks. Complex cermet parts with high densities are successfully fabricated, thereby experimentally demonstrating the feasibility of this method. The as-...
