Abstract: An assembly and a method for applying particulate building material in a 3D printer, reduces forces acting on already applied layers of the particulate building material and partially already hardened regions of the particulate building material with the application of a further layer of the particulate building material. The assembly includes, in front of a smoothing means, when viewed in a moving direction of the smoothing means, a means for discharging excess particulate building material from an accumulation in front of the smoothing means. The method includes smoothing the particulate building material applied to a surface of the building field by an applicator, with said building material collecting in an accumulation in front of the smoothing means, by controlling the height of the accumulation such that particulate building material is partially removed from the accumulation.

Abstract: The invention relates to a system and process for robot-assisted three-dimensional fabrication of continuous fiber-reinforced thermoset composites (CFRTCs). The system includes a robot and a printhead assembly having a continuous fiber feeding module, a resin coating module, and an in-situ resin curing module. The system and process use resistive Joule heating to locally cure the continuous fiber material on demand during the fabrication of the CFRTCs.

Abstract: An additive manufacturing system and an input material that overcomes that need to heat and extrude solidifying materials to create a three-dimensional structure. The system arranges subunits of the input material into repeating, interlinked subunits that can be arranged to manufacture a three-dimensional structure that is flexible but also has sufficient structural integrity to retain a desired shape during the additive manufacturing process or post-manufacturing usage. During the additive manufacturing process, the flexible input material can be manipulated and reformed to match the shape and structure of a target three-dimensional structure, upon which the manufactured three-dimensional structure is based. As elongated units of the input material are received by the additive manufacturing machine, the machine assembles the input material into the interlinked, repeating subunits, thereby removing the need to heat and extrude an input material to create a structure.

Abstract: A method (V) for producing a three-dimensional object (2) by applying and selectively solidifying a powdery construction material (13) layer by layer includes the steps:



a) applying (Z) a layer of the construction material (13) onto a construction field in a working plane (10) by means of a recoating device (14) moving in a moving direction (B) over the working plane,
b) selectively solidifying (Y) the applied layer of the construction material (13) at positions, which correspond to a cross-section of the object (2) to be produced, and
c) repeating (X) the steps a) and b) until the object is completed.




The construction material is stored during step a) in a recoating unit (40a-e) arranged at the recoating device (14) within a space between two recoating elements (42a, 42b) mutually spaced apart from each other in the moving direction of the recoating device. At least one recoating element (42b) arranged rearward with respect to the moving direction (B) of the recoating device (14) includes a roller (43a, 43b), by means of which the construction material is applied to the working plane.

Abstract: In one example in accordance with the present disclosure, a system is described. The system includes a fracture channel controller to determine fracture channels for a three-dimensional (3D) printed object. Portions of the 3D printed object along fracture channels are to be solidified to a lesser degree as compared to non-channel portions of the 3D printed object. The system also includes an additive manufacturing controller to control an additive manufacturing device. The additive manufacturing controller controls the additive manufacturing device to 1) solidify portions of a layer of powdered build material to form a slice of the 3D printed object and 2) selectively solidify fracture channels in the slice, wherein the fracture channels are solidified to a lesser degree as compared to non-channel portions.

Abstract: A method for manufacturing a part made from composite material of a thermoplastic or thermosetting matrix reinforced with fibers includes producing a structure of fibers, that is optionally pre-impregnated. The method further includes aligning and juxtaposing fibers, while stretching them between return elements, and keeping them separated from each other, so as to obtain a first layer. The method includes superimposing, on said first layer, a second layer obtained in an identical manner to the first, in which the fibers are parallel to those of the first layer and kept apart from it. The method includes repeating the superimposing operation until the desired thickness is obtained and stiffening the material making up the matrix (M) by a method that suits its nature.

The polymer here is an elastomer selected from the following group: thermoset polyurethane elastomers (PUR), thermoplastic copolyamides (TPA), thermoplastic copolyesters (TPC), thermoplastic olefin-based elastomers (TPO), styrene block copolymers (TPS), thermoplastic urethane-based elastomers (TPU), crosslinked thermoplastic olefin-based elastomers (TPV), thermoplastic polyvinyl chloride-based elastomers (PVC), thermoplastic silicone-based elastomers and a combination of at least two of these elastomers.

Abstract: The present disclosure generally relates to additive manufacturing systems and methods involving a mechanism for feeding in a desired amount of fresh recoater blade. This can be accomplished by, for example, spooling the fresh blade material from a spool. This helps prevent work stoppage when a portion of a recoater blade becomes damaged. As such, the present disclosure also relates to a system and method for detecting whether a recoater blade is damaged, and if there is damage, then causing a fresh blade portion to be fed in.

Abstract: Methods for manufacturing three-dimensional objects using an additive manufacturing technique, methods for forming dye-infused feed material for an additive manufacturing technique, and vehicles including additive manufactured components are provided. An exemplary method for manufacturing a three-dimensional object using an additive manufacturing technique includes solubilizing a dye into a medium in the form of a supercritical fluid and contacting a feed material with the medium to infuse the dye into the feed material to form dye-infused feed material. The method further includes locally melting the dye-infused feed material in selected regions of a layer corresponding to a cross-section of a three-dimensional object being formed and solidifying the dye-infused feed material into a solid layer of dye-infused material. Further, the method includes repeating the local melting and solidifying steps to form the three-dimensional object made up of a plurality of solid layers of dye-infused material.
