Professor uses 3D printed vegemite to power LEDs

The list of 3D printable materials has gotten very long and diverse over recent years, and only seems to be increasing in length at a very steady rate. But among it are some very surprising (and sometimes even edible) materials, and one Dutch professor at the University of Wollongong in Australia has just added perhaps the strangest: Vegemite. Despite all the inventive Vegemite recipes out there, no one has ever tried to 3D print it, which is exactly what professor Marc in het Panhuis has now achieved. You might know this engineering expert for a number of other 3D printing innovations. Just recently, we reported on his involvement in a 4D printed valve.
