构建材料容器和收集管结构
摘要：
一种增材制造构建材料容器包括：用于保持构建材料的储存器；构建材料出口结构，允许构建材料通过位于所述储存器的顶部部分中的出口开口离开所述储存器；纵向收集单元(313a)，用以从底部收集构建材料，并将所述构建材料引导到顶部处的所述出口开口；底部通气结构，允许通气气体进入所述储存器的底部部分。所述底部通气结构可包括通气管，以允许通气气体进入所述储存器的底部部分中。同心的收集管结构可被采用，其包括嵌套在通气管(333A，354A)内的所述纵向收集管。所述同心的收集管结构可沿着所述储存器的中心轴线安装。
摘要（英）：

An additive-manufacturing build-material container comprises a reservoir to hold build material, a build-material outlet structure to allow build material to exit the reservoir through an outlet opening in a top portion of the reservoir, a longitudinal collection unit (313a) to collect build material from the bottom and guide the build material to the outlet opening at the top, and bottom-ventingstructure to admit vent gas into a bottom portion of the reservoir. The bottom-venting structure may include a vent tube to admit venting gas into the bottom portion of the reservoir. A concentric collection tube structure may be employed including the longitudinal collection tube nested within a vent tube (333A, 354A). The concentric collection tube structure may be mounted along the central axisof the reservoir.
