In　this　study,　fine　lattice　structural　titanium　dioxide　ceramics　were　produced　by　DLP　3D　printing.　A　suitable　titanium　dioxide　ceramic　slurry　for　DLP　3D　printing　was　prepared.　TiO2　ceramic　green　body　was　prepared　by　using　a　home-made　DLP　3D　printer.　Fine　lattice　structural　titanium　dioxide　ceramics　with　a　porosity　from　50%　to　80%　were　prepared　by　optimizing　the　debinding　and　sintering　process.　The　precision　of　strut　can　reach　200　mu　m.　By　controlling　the　process　parameters　of　debinding　and　sintering,　ceramic　cracking　and　collapse　caused　by　resin　volatilization　were　effectively　avoided.　The　obtained　ceramics　were　found　to　be　rutile　phase　TiO2.　With　the　decrease　of　porosity,　the　compressive　strength　of　lattice　ceramics　can　be　increased　from　1.13　MPa　to　1.50　MPa.　The　porous　titanium　dioxide　ceramics　prepared　in　this　study　can　be　used　in　bone　tissue　engineering,　filters,　radiators　and　other　fields　in　the　future.
