3D printers are already a fairly well established fact in manufacturing industries. An image is sent to the printer, sliced into horizontal layers, which are then replicated in the material of your choice, one layer at a time, without the need to make dies for casting. This helps with the development of new designs and ideas no end.
But now, scientists at Exeter University have developed a prototype device, which uses 3D printer technology to do the same sort of thing, only with chocolate. Which means the chocolate iPhone is surely only a matter of time.
Lead scientist Dr Liang Hao told BBC News that printing in chocolate is just like printing in ink. The trick is to start with a flat cross-section of your finished image, “then you do a 3D shape – layer by layer, printing chocolate instead of ink, like if you were layering 2D paper to form a 3D shape.”
And of course, chocolate being chocolate, each layer solidifies before the next one is added.
Dr Hao says that once a commercial prototype is ready, he wants to create a chocolate-based social networking site, as a way of researching how best to use their invention for the good of mankind.
“Now we have an opportunity to combine chocolate with digital technology, including the design, digital manufacturing and social networking. Chocolate has a lot of social purpose, so our intention is to develop a community and share the designs, ideas and experience about it.”
Seriously, he really did say, “Chocolate has a lot of social purpose,” that’s how you can tell he’s a scientist.
