🚫Welcome to the future. A factory in the Netherlands 3D prints 500 tons of steaks a month. Redefine Meat company will supply German restaurants with printed steaks. Approximately 110 German restaurants are already buying "meat" from Redefine Meat. "To begin the 3D-printed meat process, scientists biopsy a sample per batch of animal stem cells depending on the desired type of meat: beef, pork, poultry or even fish." Within a climate-controlled biorreactor, these cells proliferate in vitro while submerged in a nutrient-rich serum.
