Aluminum　alloys　are　renowned　for　their　lightweight　nature,　resistance　to　oxidation,　and　impressive　mechanical　properties.　Despite　these　advantages,　their　mechanical　performance　deteriorates　significantly　in　extreme　environments.　Herein,　we　present　an　innovative　solution　by　developing　aluminum　matrix　composites　(AMCs)　that　incorporate　3D　printed　alumina　ceramic　lattices.　Our　investigation　demonstrates　a　remarkable　112.4　%　increase　in　the　strength　of　AMCs　compared　to　pure　aluminum,　with　a　concurrent　54.8　%　improvement　in　modulus　under　identical　conditions.　Additionally,　as　the　volume　fraction　of　the　ceramic　lattice　varies　from　0.21　to　0.45,　the　modulus　of　AMCs　exhibits　a　noteworthy　increase,　ranging　from　96.2　to　106.5　GPa,　surpassing　that　of　pure　aluminum　(68.8　GPa).　Notably,　even　at　temperatures　of　up　to　300　degrees　C,　the　strength　of　the　Al2O3-Al　composite　matrix　remains　stable　at　477.3　MPa.　X-ray　computed　tomography　analysis　elucidates　that　the　structural　integrity　of　these　composites　predominantly　relies　on　the　load-bearing　capacity　of　the　ceramic　lattices,　complemented　by　the　damping　effect　provided　by　the　aluminum　matrix.　This　innovative　approach　not　only　paves　the　way　for　scalable　production　of　high-strength　metal　alloys　in　the　industrial　sector　but　also　holds　promise　for　substantial　economic　opportunities　in　the　near　future.
