Design and print your own 3-D chocolate objects.

3-D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products but this is the first time the principles have been applied to chocolate. This new digital technology printer allows you to create your own designs on a computer and reproduce them physically in three dimensional form in chocolate. The project is funded as part of the Research Council UK Cross-Research Council Programme -- Digital Economy and is managed by the Engineering and Physical Sciences Research Council (EPSRC) on behalf of ESRC, AHRC and MRC. It is being led by the University of Exeter in collaboration with the University of Brunel and software developer Delcam Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. These variables then have to be integrated with the correct flow rates for the 3-D printing process. Researchers overcame these difficulties with the development of new temperature and heating control systems. Research leader Dr Liang Hao, at the University of Exeter, states that what makes this technology special is that users will be able to design and make their own products. 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 non-hazardous. There is also no wastage as any unused or spoiled material can be eaten of course! From reproducing the shape of a child's favorite toy to a friend's face, the possibilities are endless and only limited by our creativity. Researchers hope that an online retail business will host a website for users to upload their chocolate designs for 3-D printing and delivery. Dr Hao added: "In future this kind of technology will allow people to produce and design many other products such as jewellery or household goods. Eventually we may see many mass produced products replaced by unique designs created by the customer." EPSRC Chief Executive Professor Dave Delpy said: "This is an imaginative application of two developing technologies and a good example of how creative research can be applied to create new manufacturing and retail ideas. By combining developments in engineering with the commercial potential of the digital economy we can see a glimpse into the future of new markets -- creating new jobs and, in this case, sweet business opportunities." source;Engineering and Physical Sciences Research Council (EPSRC).
