In　recent　few　years,　significant　improvement　has　been　made　in　developing　largescale　3D　printer　to　accommodate　the　need　of　industrial-scale　3D　printing.　Cementitious　materials　that　are　compatible　with　3D　printing　promote　rapid　application　of　this　innovative　technique　in　the　construction　field　with　advantages　of　cost　effective,　high　efficiency,　design　flexibility　and　environmental　friendly.　This　paper　firstly　reviews　existing　3D　printing　techniques　that　are　currently　being　used　in　commercial　3D　printers.　It　then　summarizes　three　latest　development　of　largescale　3D　printing　systems　and　identifies　their　relationships　and　limiting　factors.　Thereafter,　critical　factors　that　are　used　to　evaluate　the　workability　and　printable　performance　of　cementitious　materials　are　specified.　Easy-extrusive,　easy-flowing,　well-buildable,　and　proper　setting　time　are　significant　for　cementitious　material　to　meet　the　critical　requirements　of　a　freeform　construction　process.　Finally,　main　advantages,　potential　applications　and　the　prospects　of　future　research　of　3D　printing　in　construction　technology　are　suggested.　The　objective　of　this　work　is　to　review　current　design　methodologies　and　operational　constraints　of　largescale　3D　printing　system　and　provide　references　for　optimizing　the　performance　of　cementitious　material　and　promote　its　responsible　use　with　largescale　3D　printing　technology.
