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.

The invention relates to the field of engineering machinery, and discloses a pumping control method and apparatus, a material distribution method and apparatus as well as a distribution device. The pumping control method includes: calculating an initialized pumping speed; controlling a distribution device to pump at the initialized pumping speed; and dynamically adjusting the pumping speed of the distribution device in real time according to a completed real-time distribution volume and real-time distribution time during the pumping of the distribution device until the real-time distribution volume is a desired distribution volume. Therefore, the accuracy of a final distribution volume is improved. The distribution method includes: controlling a distribution device to perform distribution at a to-be-distributed location in a preset distribution area; and after distribution at the to-be-distributed location is completed, determining a next to-be-distributed location in the preset distribution area and performing distribution at the next to-be-distributed location until distribution at each to-be-distributed location in the preset distribution area is completed. Therefore, automatic distribution is achieved.

A three-dimensional printing system for reinforced concrete and a nozzle therefore. The system employs an extruder for extruding unreinforced concrete and a concrete reinforcement feeder is for feeding one or more elongate reinforcement members. The nozzle has an outlet and is operatively connected to the extruder and the concrete reinforcement feeder to receive the unreinforced concrete from the extruder and to receive the one or more elongate reinforcement members from the concrete reinforcement feeder. The nozzle combines the unreinforced concrete from the extruder and the one or more elongate reinforcement members from the concrete reinforcement feeder into a reinforced concrete extrusion and imparts the reinforced concrete extrusion through the outlet.
