    Abstract: A composite material structure can be constructed using an airforming process that includes filling the inflated support mold with a fluid structural material and allowing the fluid structural material to harden within the support mold. Additional steps can include inflating the support mold with a first fluid, forming fluid escape outlets in the support mold, and removing the support mold after allowing the fluid structural material to harden. The first fluid can be air, the support mold can be a fiberglass resin, and/or the fluid structural material can be a concrete composite material. Fluid can escape through the fluid escape outlets during the filling. The finished structure can include multiple structural components formed from a homogenous concrete composite material and having curved and non-planar geometries. The concrete composite material can include aluminum alloy fibers.

    Abstract: Described herein relates to 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.

  • Publication number: 20240286349
    Abstract: 3D printers perform additive manufacturing by depositing heated material (commonly plastic) onto a surface from a printer nozzle. This plastic can come in many forms, including filament and pellets, and not all types of 3D printer heads are suitable for printing with all types of plastic. Moreover, certain materials are more suited to 3D printing at specific resolutions. Disclosed herein are embodiments of a 3D printer head with multiple types of printer heads configured on a single head. By comprising different printer heads that print with materials of varying coarseness and fineness, the single head can print using multiple different materials at multiple 3D-printing resolutions. It also possesses an anti-ooze mechanism to reduce errors while printing and deploys or retracts certain printer heads when they are not being used during a 3D print.

    Abstract: A printing apparatus includes a head that ejects liquid, a robot that includes a base portion and a distal end portion supporting the head and changes a relative position of the head with respect to the base portion, and a moving mechanism that moves a work relative to the base portion. A first printing operation in which the head ejects the liquid onto a first region in a printing region and a second printing operation in which the head ejects the liquid onto a second region in the printing region are performed. A main scan movement operation in which the moving mechanism moves the work relative to the base portion in the main scan direction is performed. The first region is adjacent to the second region in the main scan direction. The printing region includes a first overlapping region in which the first region overlaps the second region.

    Abstract: A device for additive manufacturing of a component on a work surface has a material dispensing unit for depositing a building material. The device has, moreover, an actuator assembly, to which the material dispensing unit is fastened, and which is configured to move the material dispensing unit relative to the work surface. The actuator assembly has at least one strut, along the longitudinal axis of which the material dispensing unit can be moved. At least one of the struts of the actuator assembly can be fastened for sufficient structural stability to a stand frame which is set up next to the work surface and is independent of the strut.

  • Publication number: 20240286352
    Abstract: Disclosed is a heated printer bed mounted to a kinematic coupling system that permits thermal expansion of both the bed and a support truss. One kinematic couple couples the bed to the support truss and a second kinematic couple couples the support truss to a frame of the printer. Both kinematic couples ensure that a common geometric center along each kinematic couple is maintained despite thermal expansion of the printer bed and the support truss occurring at different rates. The kinematic coupling system mitigates deformations to 3D-printed items from the effects of thermal expansion.

  • Publication number: 20240286353
    Abstract: According to some aspects, an additive fabrication device and a build platform suitable for use within an additive fabrication device are provided. The build platform may include a build surface on which material may be formed by the additive fabrication device when the build platform is installed within the additive fabrication device. According to some embodiments, the build platform may include a flexible build layer and at least one removal mechanism configured to be actuated to apply a force to the flexible build layer. Such actuation may cause the flexible build layer to deform, thereby enabling separation of material adhered to the build surface from the build platform. According to some embodiments, the build platform may comprise a restorative mechanism that acts to return the flexible build layer to a flat state so that subsequent additive fabrication may form material on a flat build surface.

  • Publication number: 20240286355
    Abstract: Techniques for improved efficiency of sintering in additive fabrication are described. According to some aspects, mechanisms for depositing and leveling source material are combined with a mechanism for heating the material. In some embodiments, one or more heating elements may be arranged to lead and/or follow a material deposition mechanism such that heat may be applied to the build region in concert with deposition of material. As a result of this technique, the heating and depositing steps may be performed closer together in time and/or heat may be applied more directly to the material than in conventional systems. As a result, greater control over material temperature may be achieved, thereby avoiding excess temperature exposure and subsequent undesirable changes to the material.

  • Publication number: 20240286356
    Abstract: 3D printers perform additive manufacturing by depositing heated material (commonly plastic) onto a surface from a printer nozzle. During a 3D print, nozzles may “ooze” excess material, leading to deformities in 3D prints. Disclosed is an anti-ooze mechanism that covers up 3D printer nozzles when they are not being used. A servo moves a nozzle shield in front of and away from a nozzle while a 3D print is happening so that no ooze drips onto a 3D print or otherwise escapes from a printer nozzle onto the printer bed. Moreover, the servo can move the nozzle shield quickly to minimize the amount of time that a nozzle spends uncovered, and the nozzle shield is also capable of “scraping off” excess material from the nozzle head.

    Abstract: A system and method is provided to construct a structure using three dimensional printing of extrudable building material to a wall surface of a structure. According to one embodiment, a printing assembly is moveably disposed above the surface, and extrudable building material is applied from a nozzle onto the surface. One or more profilometers measure at periodic intervals along a geometric cross-section of a bead of extrudable building material. One or more controllers compare the measured cross-section to a predetermined, target cross section and one or more controllers periodically change, for example, the rate of application and/or the viscosity of the extrudable building material applied along the longitudinal axis. The nozzle direction can change, and the profilometers can be rotated about the nozzle along different longitudinal axes, or directions, depending on the wall locations being formed.
