Abstract: An additive printing apparatus and method for printing an object. The additive printing apparatus includes a print area having a movable build plate and a light projector. The apparatus includes a first movable tray with a first resin and second movable tray with a second resin When the first movable tray is positioned in the print area, the build plate is moved toward the first resin and the light projector is activated to cure a portion of the first resin to form a first layer of the object. When the second movable tray is positioned in the print area, the build plate is moved toward the second resin and the light projector is activated to cure a portion of the second resin to form a second layer of the object.

Abstract: A virtual window for an aircraft includes a frame having panels defining a cavity. The frame is configured to be positioned in an outer wall of the aircraft. The frame has a top, a bottom, a front, a rear, and opposite first and second sides. The front is configured to face a main cabin of the aircraft and the rear configured to face a skin of the aircraft. A display is received in the cavity and includes a screen at the front configured to face the main cabin. A camera is operably coupled to the display and is configured to be positioned in the outer wall and face an exterior of the aircraft. The virtual window includes a power source in the frame being electrically coupled to the display and the camera for powering the display and the camera.
