Cement 3D printing material testing device and using method thereof

The invention relates to a cement 3D printing material testing device and a using method thereof. The cement 3D printing material testing device comprises two vertical supports arranged in a left-right spaced mode, wherein a plurality of horizontal cross beams are jointly mounted between the two vertical supports, and a lifting base is jointly mounted in front of the multiple cross beams through a lifting driving mechanism; a back plate moving in the length direction of the lifting base is mounted on the front side of the lifting base through a translation driving mechanism. A discharging assembly is mounted on the front side face of the back plate. The discharging assembly structurally comprises an upper plate and a lower plate which are arranged up and down at an interval, wherein the rear end of the upper plate is fixedly connected with the back plate, and the upper plate and the lower plate are connected through a screw rod; a detachable cylinder is supported above the lower plate through an upper plate,
