A Z-axis that is integrated with storage, commixture and extrusion of materials, including a vertically-moving bucket, and a vertically-moving unit connected to the vertically-moving bucket. The vertically-moving unit can drive the vertically-moving bucket to move vertically. The vertically-moving bucket is used to store printing materials. A printing nozzle connected to the vertically-moving bucket is provided at the bottom of the vertically-moving bucket, which is connected with the printing nozzle through a stirring unit. The vertically-moving bucket replaces the existing vertically-moving axis, so that the printing nozzle can directly communicate with the vertically-moving bucket without pipelines to connect the printing nozzle to the vertically-moving bucket. Also, a 3D building printer that does not need to erect a relaying bucket in the sky, which solves the problem of pipeline blockage and cleaning.
