Additive manufacturing of Proton-Conducting Ceramics by robocasting with integrated laser postprocessing

Year: 2024
Type: article
Abstract: A hybrid system combining robocasting and NIR laser postprocessing has been designed to fabricate layers of mixed proton-electron conducting Ba 0.5 La 0.5 Co 1-x Fe x O 3-δ ceramic.The proposed manufacturing technique allows for the control of the geometry and microstructure and shortens the fabrication time to a range of a few minutes.Using 5 W laser power and a scanning speed of 500 mm⋅s -1 , sintering of a round-shaped layer with an 8 mm radius was performed in less than 2 s.The single phase of the final product was confirmed by X-ray diffraction.Various ceramic-to-polymer weight ratios were tested, showing that various porosities of microstructures of ~30 -35 % and ~19 % can be obtained with 2:1 and 4:1 loading respectively.
