For £50-£80 or about $80-$130, you can have a sculpture of your face made from dark, milk or white chocolate by Choc Edge, a British company that specializes in printing 2D/3D chocolates.
Chocolate, regardless of form, tends to melt in the hand and the mouth and pretty much any other warm place. 3D printers are generally incredibly warm, given that they often “print” hard materials by burning and melting them.
To create a shape the printer prints incredibly thin layers of chocolate, some as small as .05mm. These quickly harden and more chocolate can be lumped on, until it eventually creates whatever chocolate art you’re hoping to make.
