Abstract This work investigated sintering procedures for high‐porosity alumina ceramic cores fabricated by digital light processing 3D‐printing. Results showed that increasing temperature reduced cristobalite while enhancing mullite formation. Flexural strength initially increased then declined with temperature, exhibiting an inverse relationship porosity. Faster heating rates (up to 4°C/min) decreased content and size, yielding peak of 23.73 MPa. Extended holding time porosity but caused first increase decrease, peaking at 29.06 Optimal performance was achieved 1450°C 4°C/min 120 min hold, producing 28.28 MPa strength, 41.40% porosity, 2.15 g/cm 3 density. The process successfully balanced high mechanical properties temperatures.
