The stem cells were then shown to grow, the university added, allowing users to start printing tissues without having to grow the cells separately. “Our unique gel keeps the stem cells alive whilst producing a material which is stiff enough to hold its shape but soft enough to be squeezed out the nozzle of a 3D printer.” 3D printing methods are increasingly being used in the field of prosthetics and healthcare; earlier this year, US researchers found a way to develop soft robots with embedded touch sensing, using a 3D printed conductive ink. 3D printing with light: Scientists create 3D holograms. We talk with John Kawola, president of Ultimaker North America, about the world of 3D printing, Ultimaker’s strategy, and how 3D printing will change over the next two decades. We have a T-Rex skull, a 300,000 year old hominid jaw, 3D printed mountain ranges, and some Arduino tools to show off along with CR-10 and MOD-t 3D printers. Here’s how 3D food printers are changing what we eat.
