A recent study in the Journal of Food Engineering explores how 3D printing affects the structure of processed cheese. How gross would 3D-printed Velveeta nachos be? A bevy of researchers from University College Cork in Ireland decided to find out.
They melted a commercially available processed cheese (think American cheese, not cheddar) and put it through a modified 3D printer that printed the cheese out at either a fast or a slow speed. The cheese was printed out into cylinders that were then cooled for 30 minutes and put in the refrigerator for a day. After that 24-hour refrigeration period, the researchers took the cheese out of the fridge to check its texture and chemical structure.
