3D printing is revolutionizing medicine: Researchers at Tel Aviv University have 3D printed a heart from a patient’s own cells in a breakthrough that could revolutionize organ transplants, according to Bloomberg. The heart, about the size of a rabbit’s, is the first to be printed with ink from the patient’s own biological material, complete with blood vessels, ventricles, and chambers. From using 3D printing to upcycle food waste and sell it on to fancy restaurants, to printing food for caterers and bakeries, the 3D food printing industry is estimated to be worth USD 500 mn by 2023, according to a report by the FT. The trend in food tech doesn’t stop there, though. The next stage is making food tailored to a person’s DNA. (watch: runtime 3:50).
