The video shows a close-up of a 3D printer's extruder head as it moves over a gray object. The object appears to be a small, rectangular block with a hole in the center. The extruder head is made of metal and has a nozzle that dispenses the material. The printer is printing the object in a layer-by-layer fashion, with the nozzle moving back and forth to create the object's shape. The background is blurred, but it seems to be a workshop or factory setting.
