通过粉末喷射进行3D打印的粉末供给系统和方法
摘要：
一种用于通过喷射至少第一粉末进行3D打印的设备的切换系统(1)，包括主体(10)，该主体限定：-被构造为接收气体的至少一个第一上游气体导管(G1)；-被构造为接收第一粉末的至少一个上游粉末导管(A)；-用于排出第一粉末的至少一个第一下游排出导管(Ra)；以及-被构造为给喷嘴进料的下游工作导管(T)，该喷嘴被设计用于沉积至少第一粉末。该系统还包括分配器(2)，该分配器能在静止位置与至少第一供应位置之间相对于主体移动，优选围绕轴线(D)旋转地移动，在静止位置，第一上游粉末导管经由分配器流体地连接至第一下游排出导管，而在第一供应位置，第一上游粉末导管经由分配器流体地连接至下游工作导管。
摘要（英）：

Disclosed is a switching system for a facility for 3D printing by spraying at least a first powder, including a body defining: at least one first upstream gas conduit configured to receive a gas; at least one first upstream powder conduit configured to receive the first powder; at least one first downstream discharge conduit for discharging the first powder; and a downstream work conduit configured in order to supply a nozzle designed for depositing at least the first powder. The system further includes a distributor that is movable with respect to the body, preferably in rotation about an axis, between a rest position, in which the first upstream powder conduit is fluidly connected, via the distributor, to the first downstream discharge conduit, and at least a first supply position, in which the first upstream powder conduit is fluidly connected, via the distributor, to the downstream work conduit.
