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.},
