The video shows a close-up of a 3D printer with a hand holding a small piece of plastic in front of it. The printer is in the process of printing an object, and the hand is moving the plastic piece back and forth to demonstrate the printing process. The printer is black and has several wires and components visible. The hand is holding the plastic piece between the thumb and index finger, and the plastic piece appears to be a small, cylindrical object. The background is blurred, but it seems to be a workshop or lab environment.
