3D chocolate printer
Hardware of a very different stripe made our silicon.com photo stories with the news that the University of Exeter has created a machine that can print 3D objects - like the one above - in chocolate.
The University's research team initially found chocolate a difficult medium to work with as it requires precise heating and cooling cycles that had to be integrated with flow rates for the 3D printing process. However, they successfully developed a temperature control system that enables chocolate to be printed by the machine.
To find out how it works, see Come in Willy Wonka, your time is up - meet the printer that prints in chocolate.
