Sufficient　reinforcement　is　crucial　for　three-dimensional　(3D)　printed　concrete　structures.　In　this　study,　continuous　and　simultaneous　micro-cable　reinforcing　methods　are　investigated　to　accommodate　the　3D　flexible　and　automatic　characteristics　of　additive　manufacturing　processes,　and　to　satisfy　the　mechanical-property　requirements　for　construction　applications.　Different　manufacturing-related　micro-reinforcements　and　printing　configurations　are　designed　for　3D　printing　cable-geopolymers.　The　specimens　were　subjected　to　three　different　types　of　loading　conditions　(compressive,　shear,　and　tensile)　to　gain　a　better　understanding　of　the　composite　behavior.　The　results　revealed　interesting　behaviors:　under　compressive　loadings,　the　confinement　effect　of　the　micro-cables　is　fundamental　in　producing　additional　strength,　ductility,　and　toughness.　The　print　path　must　be　considered　for　determining　the　confinement　levels.　Micro-cables　increase　the　compressive　strength　by　50.0%　in　a　certain　print　path.　The　shear　strength　depends　primarily　on　the　geopolymer　weak　planes＇　directions　between　two　filaments　instead　of　the　embedded　cable　reinforcements.　The　tensile　response　is　primarily　governed　by　the　micro-cable　reinforcements　and　the　configurations,　which　depend　on　the　print　paths.　In　certain　configurations,　the　micro-cables　result　in　158%　and　43.8　times　increase　in　tensile　strength　and　strain,　respectively.　This　study　provides　valuable　insights　into　the　behavior　of　3D-printed　geopolymer　composites　with　micro-cable　reinforcement,　which　is　necessary　for　designing　and　manufacturing　complex　structures　using　this　novel　reinforcement　method.
