  • Publication number: 20200016837
    Abstract: A system and corresponding method to move a rod of build material in a three-dimensional (3D) printing system uses a pusher. The rod of build material has distal and proximal ends relative to an extrusion head. The distal and proximal ends having distal and proximal end surfaces, respectively. The pusher engages with the rod and applies an axial force to at least a portion of the distal end surface of the rod for at least a portion of a path the rod travels toward the extrusion head. The axial force actuates the rod of build material without alteration, such as by shaving, fracturing, or otherwise deforming the rod of build material.

  • Publication number: 20190322046
    Abstract: A system and corresponding method to move build material in a three-dimensional (3D) printing system uses a gripper. The gripper is arranged to apply at least two opposing lateral forces to the build material. The at least two opposing lateral forces are applied to the build material, in conjunction with linear motion of the gripper, for at least a portion of a path the build material travels toward an extrusion head.

  • Publication number: 20180304353
    Abstract: Assemblies and support structures facilitate fabricating objects through additive manufacturing. A support structure include a column having a vertical channel extending along a surface of the column, the vertical channel being formed to couple to a motion system of a build plate. A plurality of arms extend laterally from an upper portion of the column, each of the plurality of arms having a respective rail channel aligned in a common plane. The rail channels secure respective rails of a motion system of a print head, and the plurality of arms secure the respective rails at a fixed position relative to the motion system of the build plate. A plurality of feet extending laterally from a lower portion of the column.

  • Publication number: 20180297288
    Abstract: Systems, methods, and apparatus are introduced for controlling an output flow of a build material from an extrusion assembly used for printing a three-dimensional (3D) object. Control of the output flow is based on an input control value that may be a function of a hydraulic capacitance and a hydraulic resistance, representing hydraulic capacitance values and hydraulic resistance values, respectively, associated with the build material, the extrusion assembly, or a combination thereof at one or more locations of the extrusion assembly relative to a melting zone of an extrusion head of the extrusion assembly as well as a target output flow. The input control value enables the output flow to match the target output flow. The hydraulic capacitance and resistance values account for interaction of the build material and a mechanical mechanism of the extrusion assembly driving extrusion of the build material.
