Can you imagine people will enjoy a mouth-watering, delicious ribeye steak (肉眼牛排) without harming a single animal? Aleph Farms, a food-tech company, just created the world’s first 3D-printed ribeye steak. The thick and juicy slab (厚片) smelt and tasted just like a steak. But unlike any steak found on a menu or store shelf today, this one didn’t come from a slaughtered animal.

Scientists printed it with a machine which is much like a standard 3D-printer. The difference is that this printer used cells (细胞) as a form of living ink. The technology includes the printing of real living cells that are grown in a lab. They are given nutrients (养分) and kept at a temperature that lets them keep growing.

Interest in this kind of new meat has grow n in recent years, partly because the technology shows it is possible. Supporters say that if meat can be printed, then no animal would need to lose its life to become people’s food. So, there are plenty of reasons to be excited about the 3D-printed steak.

However, we can’t get this new meat on the store shelf yet. Making meat this way is much harder and costs more than raising and killing an animal. One of the most expensive parts is the cell-growth medium (培养基). This mix of nutrients keeps the cells alive and dividing. If scientists can find lower-cost methods, we’ll be in with a chance of getting beef without killing.
