  • Patent number: 9808993
    Abstract: The present invention provides methods, processes, and systems for the manufacture of three-dimensional articles made of polymers using 3D printing. A layer of prepolymer is deposited on a build plate to form a powder bed. The deposited powder bed is heated to about 50° C. to about 170° C. Then, a solution of activating agent is printed on the powder bed in a predetermined pattern, and a stimulus is applied converting the prepolymer to the final polymer. After a predetermined period of time, sequential layers are printed to provide the three-dimensional article. The three-dimensional object can be cured to produce the three-dimensional article composed of the final polymers.

  • Patent number: 9804395
    Abstract: The disclosure includes a system and method for calibrating a binocular optical see-through augmented reality display. A calibration application renders one or more images of a virtual object on the one or more displays of the human interface device, and receives a user input to adjust a position of the one or more images on the one or more displays. In response to the input, the calibration application identifies a first and second boundary of a target range surrounding a real-world object at a first and second depth, respectively. The calibration application determines a first and second disparity corresponding to the first and second boundary and may record the disparities in relation to the depth of the real-world object.
