A year ago, Trend Hunter first featured 3D object printers. Now, Evil Mad Scientists has created the Candyfab 4000, which prints 3D objects made of sugar. It's the perfect combination of mad science and free-form, delicious candy. The process takes time, but since when was anything of value quick to come by? The machine will be unveiled next week at the Bay Area Maker Faire that promotes the DIY mentality for inventors all over.
