Abstract: In this work, the synthesis of high-entropy perovskite-type oxides from multimetallic polymeric precursors and their shaping by photolithographic additive manufacturing is investigated. Thermosets with well-controlled complex geometries are produced by digital light processing using the multimetallic organic-inorganic hybrid resin developed in this work and converted into ceramics by thermal debinding and sintering. The high-entropy perovskite-type oxides are produced at 1500 °C, they retain the printed geometry with high shape fidelity. The orthorhombic crystal structure is identified by the Rietveld refinement of high-resolution synchrotron X-ray data; elemental and spectroscopic characterizations suggest the composition Sr(Ti 0.22 Zr 0.22 Hf 0.23 Mn 0.15 Sn 0.18)O 2.85. The use of aqueous polyethylene glycol as a binder and porogen greatly reduces the formation of cracks and creates evenly distributed micropores, which leads to improved compressive strength of the specimens. The compressive strength of 0.94 MPa is highest for materials printed from the resins with 3 wt% PEG in the woodpile-like geometries. [ABSTRACT FROM AUTHOR]
