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.

A dispensing system for an additive manufacturing includes a powder reservoir that contains powder to form an object, and an array of nozzles positioned at a base of the powder reservoir over a top surface of a platen where the object is to be formed. The powder flows from the powder reservoir through the nozzles to the top surface. A respective powder wheel in each nozzle controls a flow rate of the powder. Each wheel has multiple troughs on surface of the wheel. When a motor rotates the wheel, the troughs transport the powder through the nozzle. The rotation speed of the wheel controls the flow rate. For solid parts of the object, the wheel rotates and allows the powder to be deposited on the top surface. For empty parts of the object, the wheel remains stationary to prevent the powder from flowing to the surface.
