In this work, the Direct Ink Writing (DIW)technique was used to produce three-dimensional Ti
AlC ceramic components with high, uniform porosity. Suitable formulations were developed, with appropriate rheological properties for extruding thin filaments through a nozzle with a diameter of 810 μm. The main rheological properties of the inks were investigated to evaluate their behavior and flowability during the printing process. Porous Ti
AlC lattices were fabricated, in selected conditions, with uniform pore size and good interconnectivity, and sintered at 1400 °C in Ar. Total porosity ranged from ∼44 to ∼63 vol%, and the mechanical strength ranged from ∼43 to 83 MPa. The influence of the ink composition and heat-treatment conditions on the phase composition of the 3D porous structures was also evaluated.
