Lattice　structures　have　been　proven　capable　of　a　wide　range　of　engineering　applications　due　to　their　complex　design　arrangements,　such　as　periodicity,　topology,　and　morphologies.　Yet,　developing　a　hybrid　design　is　challenging　due　to　limitations　of　node　boundaries,　material,　and　fabrication　constraints　for　improving　mechanical　performance.　To　overcome　these　challenges,　hybrid　designs　were　developed　here　using　the　vat　photopolymerization　technique　by　grading　the　bend-　and　stretch-dominant　strut　morphology　in　parallel　and　perpendicular　directions.　Firstly,　numerical　simulations　predicted　the　unit　cell　performances,　and　then　the　structural　behavior　of　periodically　arranged　3D-printed　elastomeric　lattices　was　also　investigated.　As　a　result,　hybrid　design　provided　a　better　performance　strategy　under　high　load　conditions,　including　a　significant　amount　of　mechanical　performance　(7　times)　than　the　uniform　lattice　topology.　In　addition,　a　vat　photopolymerizationbased　3D　printing　technique　was　investigated　by　introducing　a　high-loaded　silica　filler　in　the　polymer,　as　a　filler　reinforcement　exhibiting　the　advantages　of　enhanced　stiffness　(12　times)　and　reduced　buckling　to　the　lattices.　Finally,　the　performance　of　hybrid-graded　design　was　examined　via　filler-coated　surfaces,　which　could　provide　insight　into　their　ability　to　adapt　to　lightweight　devices　and　engineering　applications.
