Abstract

In this work, the Direct Ink Writing (DIW)technique was used to produce three-dimensional Ti 2 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 2 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.
