3D　printing　technology　was　introduced　into　the　manufacturing　of　ceramic　components.　To　obtain　a　new　light-weight　multifunctional　structure　with　novel　structure　and　excellent　performance,　and　promote　the　deep　com-bination　of　additive　manufacturing　and　optimization　design,　ZrO2(3Y)/Al2O3　hollow　lattice　structure　ceramics　with　two　kinds　of　high　precision　and　different　porosity　were　prepared　by　vat　photopolymerization　in　this　paper,　and　the　process　optimization,　microstructure　evolution,　and　performance　were　studied.　The　hollow　lattice　structure　with　good　molding　accuracy　and　porosity　of　35　%-55　%　was　prepared　by　component　design,　opti-mization　of　slurry,　degreasing,　and　sintering　process,　which　effectively　avoided　the　ceramic　cracking　and　collapse　caused　by　resin　volatilization.　When　the　Al2O3　content　was　6　wt%,　dense　ZrO2(3Y)/Al2O3　ceramics　with　grain　refinement,　excellent　microhardness,　and　fracture　toughness　were　obtained.　The　relationship　between　lattice　structure　and　compressive　strength　was　analyzed　by　simulation　and　compressive　test.　The　results　show　that　the　compressive　strength　of　the　two　hollow　lattice　structures　decreases　with　the　increase　of　porosity.　The　maximum　compressive　strength　of　35　%-face-centered　cubic　(FCC)　hollow　lattice　structure　is　326　MPa,　which　is　significantly　higher　than　that　of　body-centered　cubic　(BCC)　structure　(240　MPa)　with　the　same　porosity.　The　hollow　lattice　ceramic　structure　with　good　comprehensive　performance　and　lightweight　will　lay　a　foundation　for　the　application　of　industrial　heat　insulation,　high　temperature　catalysis,　and　purification　carrier　in　the　future.
