Food printing isn’t a wild idea anymore. For example chocolate printing, it uses the FDM technique to print chocolate. Such a printer has approximately the same size as a 3D printer for domestic use. Nowadays it’s mainly used by bakers to customize their pastry.
The idea of food printing in the future will go much further. For example that you can download a recipe on the Internet, send it to the printer and when it’s ready you can take place at the table and start to eat.
It would also be possible to print a type of food with a shape of another type of food. Mix different tastes and create new tastes. A new world will be opened for the gastronomic sector.
