UK researchers create first 3d chocolate printer

The 3d printer makes use of a new digital technology that allows chocolate to be squirted out onto a particular pre set design and then gradually layered and cooled to create a three dimensional, edible sculpture. Although just a prototype at the moment, research leader Dr Liang Hao of the University of Exeter's College of Engineering, Mathematics and Physical Sciences, believes the device could give the manufacturing and retail industries a much needed boost. "What makes this technology special is that users will be able to design and make their own products," he said. "In the long term it could be developed to help consumers custom design many products from different materials, but we've started with chocolate as it is readily available, low cost and nonhazardous." Another advantage of the printer, as Dr Hao points out, is that any unused or spoiled material can be eaten. In the future, he sees the technology being used to produce and design many other products, such as jewellery and household goods. "Eventually, we may see many mass produced products replaced by unique designs created by the customer," he said. The research was carried out in collaboration with Brunel University and software developer Delcam. It was funded by the Engineering and Physical Sciences Research Council.
