Alumina is a widely available low-cost engineering ceramic used in different rugged and harsh environments. Most of the alumina parts are produced by conventional powder metallurgy techniques. But the fabrication of complex alumina parts in traditional processes is difficult due to the complexity of the manufacturing process. Direct ink writing is one of the additive manufacturing techniques that build an object in a layer-by-layer manner according to the computer-aided design. To prepare alumina inks, Pluronic F-127 was used to form a hydrogel. The resultant ink consisted of 65 wt.% of alumina (solid loading), and the rest 35 wt.% was Pluronic F-127 hydrogel. Rheological observations showed that the prepared ink is shear thinning in nature which enables the ink to flow smoothly from the nozzle. From the differential scanning calorimetry (DSC) studies, it is observed that all of the organic binder is removed before 500 °C. Subsequently, the alumina sample was sintered at 1300 °C for 90 min in a muffle furnace. The scanning electron microscopy (SEM) image of the fracture surface of sintered sample at 1300 °C showed the partial sintering with open porosities. The resultant structure shows that direct ink writing can be used to obtain a porous alumina microstructure.
