阅读说明：本技术 用于输送用于打印三维(3d)对象的材料的系统和方法 (System and method for delivering material for printing three-dimensional (3D) objects ) 是由 亚伦·罗尼·沙菲尔 于 2018-11-04 设计创作，主要内容包括：一种用于将多个层的粉末输送到用于打印至少一个3D对象的三维(3D)打印系统的输送系统,该输送系统包括：具有圆形光敏外表面的可旋转滚筒、包括用于存储粉末的容器的料斗单元,其中料斗单元被配置为将粉末分配到可旋转滚筒的光敏外表面上。输送系统还包括包含具有导电外表面的可移动输送板的输送单元、用于将输送板移动到3D打印系统的工作室的引擎、被配置为给可旋转滚筒充电的一个或更多个充电电极、被配置为给输送板充电的充电单元。可移动输送单元还被配置为：将分配的多个层从可旋转滚筒外表面电吸引和相继吸引到其导电外表面；以及通过将吸引的多个层电排斥到工作室中而将吸引的多个层转移到工作室。(A transport system for transporting multiple layers of powder to a three-dimensional (3D) printing system for printing at least one 3D object, the transport system comprising: a rotatable drum having a circular photosensitive outer surface, a hopper unit comprising a receptacle for storing powder, wherein the hopper unit is configured to dispense powder onto the photosensitive outer surface of the rotatable drum. The transport system also includes a transport unit including a movable transport plate having an electrically conductive outer surface, an engine for moving the transport plate to a working chamber of the 3D printing system, one or more charging electrodes configured to charge the rotatable drum, a charging unit configured to charge the transport plate. The movable transport unit is further configured to: electrically and sequentially attracting the dispensed plurality of layers from the outer surface of the rotatable drum to the electrically conductive outer surface thereof; and transferring the attracted plurality of layers to the working chamber by electrically repelling the attracted plurality of layers into the working chamber.)
