In particular, when 3D printing is performed with cement-based binders, the binder solidifies due to the tendency of the binder to hydrate. Therefore, when printing large components, the material tends to solidify inside the mixing drum too long, hindering the extrusion. At present, most of the methods adopted for 3D printing of large components adopt that a bottom part component is firstly processed, when a material begins to solidify, printing is firstly suspended, then slurry is prepared again, and an upper layer component is continuously printed.
