  • Patent number: 10394202
    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.

  • Publication number: 20180263383
    Abstract: A memorabilia support system. The memorabilia support system includes a base having a torso portion having a front side and a rear side. An upper mounting bracket is disposed on an upper end of the rear side, the upper mounting bracket having at least one aperture thereon, and a lower mounting bracket is disposed on a lower end of the rear side, the lower mounting bracket having at least one aperture thereon, wherein each aperture is configured to receive a fastener therethrough. An exemplary embodiment includes a mounting plaque to which the base may be secured via the fasteners. The base is configured to support an article of clothing such as a sports jersey, while the mounting plaque is securable to a surface such as a wall in order to display the article of clothing.

  • Publication number: 20170052516
    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.

  • Publication number: 20170052531
    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.

  • Publication number: 20170050388
    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.

  • Publication number: 20170050382
    Abstract: A three-dimensional (3D) printer and method of 3D printing including receiving a 3D model of an object to be printed, receiving information including material properties of the materials to be extruded, and generating a set of sensor-based printer control parameters to print the object on the 3D printer based, at least in part, on sensor input.

  • Publication number: 20170050381
    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.

  • Publication number: 20060221433
    Abstract: An optical switching device contains an active stage coupled to a passive stage. The index of refraction in the active stage is variable to change the entry direction of a light beam into the passive stage, which has a fixed index of refraction. Because the light beam can enter the passive stage at different angles, the exit direction of the light beam from the passive stage can be changed. The resulting optical switch allows switching without any mechanical components.
