Your post got me thinking, why not use chocolate 🍫 in 3D printer (of course I don't mean feeding chocolate into a normal 3D printer, but a special machine). Chocolate also melts with heat, and solidifies when it cool down. It also stick to near-by solid chocolate when it is in liquid form.🤓
So this got me searching online to see if such device exists. Apparently there are multiple companies producing such printers:
