This bowl should be made out of ceramic because it is a food safe 3D printing material. It is meant to be used while travelling through space. Because of the micro-gravity when travelling, food has to be eaten one pouch at a time. This bowl is designed to mix foods (such as salad and dressing or shrimp, pasta and sauce). The top lid opens and closes to allow astronauts to squeeze in their different pouches, close and mix. They can also eat from this opening.
