Abstract: A printed 3D functional part includes a 3D structure comprising a structural material, and at least one functional electronic device is at least partially embedded in the 3D structure. The functional electronic device has a base secured against an interior surface of the 3D structure. One or more conductive filaments are at least partially embedded in the 3D structure and electrically connected to the at least one functional electronic device.

Abstract: Calibration and control of a 3D printing device is disclosed. In one aspect, sensor-based feedback may be used to iteratively determine and align line height calibration settings of the 3D printing device. In another aspect, the 3D printing device may include an instruction pre-processor to detect placeholder data in received machine instructions and to replace the placeholder data with instructions that are executable by the 3D printing device.

Abstract: A composite waterborne dispersion for 3D printing. The dispersion includes a composition containing an aqueous dispersion of polymer particles; an associative thickener; and a functional filler. The functional filler may be conductive particles, fumed silica, milled glass fibers, polydimethylsiloxane, eutectic metal particles, carbon fiber, thermally insulating particles, thermally conductive particles, ferromagnetic particles, particles with high acoustic impedance, low-k dielectric particles, or high-k dielectric particles. The composition has a yield stress >0 Pa, the yield stress being at least one of dynamic yield stress and static yield stress. The composition is film-forming when dried.

Abstract: A three-dimensional (3D) printer device includes a first extruder configured to deposit a material on a deposition platform, an actuator coupled to at least one of the first extruder or the deposition platform, and a controller coupled to the actuator. The controller is configured to cause the first extruder to deposit a first portion of the material corresponding to a first portion of a physical model. The controller may be configured to cause the first extruder to be cleaned, purged, or both, after the first extruder deposits the first portion of the material. The controller may be configured to cause the first extruder to deposit a second portion of the material after the first extruder is cleaned. The second portion of the material corresponds to a second portion of the physical model.

Abstract: A method includes obtaining first model data specifying a first three-dimensional (3D) model of a first object and obtaining second model data specifying a second 3D model of a second object. The first model data indicates a location of the first 3D model relative to a model space and the second model data indicates a location of the second 3D model relative to the model space, where the second 3D model intersects the first 3D model in the model space. The method further includes processing the first model data and the second model data to generate machine instructions executable by a 3D printing device to generate a physical model of the first object, the physical model defining a void region to receive a physical instance of the second object.

Abstract: A three-dimensional (3D) printer device includes an extruder configured to deposit a material on a deposition platform, an actuator coupled to at least one of the extruder or the deposition platform, and a controller coupled to the actuator. The controller is configured to cause the extruder to deposit a first portion of the material corresponding to a first line, and after depositing a second portion of the material corresponding to a first end of the first line, to cause relative motion of the extruder and the deposition platform such that the extruder moves back along the first line while the extruder concurrently moves away from the deposition platform.

Abstract: A method include obtaining model data specifying a three-dimensional (3D) model of an object. The method also includes generating first machine instructions executable by a 3D printing device to generate a first portion of a physical model of the object by depositing material using a syringe extruder. The first machine instructions indicate a first value of a pressure setting, the pressure setting indicating a pressure to be applied to the syringe extruder. The method also includes generating second machine instructions executable by a 3D printing device to generate a second portion of the physical model of the object by depositing material using the syringe extruder. The second machine instructions indicate a second value of the pressure setting, the second value different from the first value.
