These biscuits didn’t come out of the oven, instead they were printed in 3D.
Layer by layer a mixture of flour, sugar and fat was laid down. Each new layer was ‘baked’ onto the layers below. Afterwards whatever powder hadn’t been baked could be simply wiped away. The makers gave each biscuit a different taste; the pentagon tastes of ginger nut. After decades of work developing 3D printing, innovation has been moving apace in recent years. Printers are dropping in price, getting easier to use and becoming more widely known among the general public. So it is only to be expected that in a few years’ time you won’t believe your eyes in some restaurants. In fact, Dutch researchers have already made a hollow world globe and filled it with different flavours.
Like to hear more? TNO researcher Kjeld van Bommel will be telling more about 3D printing at the Science Cafe. Come along to the Science Cafe at Café Loburg on 26 February. Starts 19.45 and entrance is free.
