Abstract: A three-dimensional object printer ejects drops of a build material from a plurality of ejectors in a first printhead to form an object on a first region of a member and ejects drops of a support material from a plurality of ejectors in a second printhead to support the object on the first region of the member. The second printhead ejects drops of the support material onto a second region of the member that is separate from the first region to form a substrate layer.

Abstract: Systems, devices, and methods for three-dimensional printing are provided. The systems, devices, and methods provide for high throughput printing by allowing for parallel extrusion within a single vertical layer of the printed object, i.e., parallel extrusion within an x-y coordinate plane.

In some embodiments, the extruder can include a printing plate that includes a plurality of apertures defined by conductive elements extending in a grid-like manner. The printer can be designed such that material is disposed to a build platform through the apertures only when the aperture is heated on all four sides, for instance by running current through the conductive elements that define the aperture.

Abstract: A three-dimensional printer (100) having a means for cooling (124) the uppermost surface of a material bed in a region immediately before a deposited layer of material (e.g. powder) at the uppermost surface is separated from a protective sheet (116). The protective sheet (116) provides a physical barrier between the deposited layer of material and a thermal print head (114) during printing. The separation of the protective sheet from the material bed may occur to create a distribution gap for a new layer of powder to be deposited (118). The cooling means may facilitate separation of the protective sheet from the deposited layer, and especially from the portion of that layer that has been heat-treated in the preceding printing pass. The cooling means may be an actively cooled surface on a separator that formed part of the print head.

Abstract: A method for performing resin infusion into a dry reinforcement on a layup mandrel comprises placing resin at a resin zone on the mandrel; bagging the reinforcement and the resin with a bagging film; heating the resin while applying compaction pressure to the bagging film to cause the resin to be infused into the reinforcement; and creating a pressure differential outside of the bagging film over the resin zone to control rate and pressure at which the resin is infused into the reinforcement. As a result, the resin pressure and infusion rate are controlled independently of the compaction pressure on the reinforcement.
