If you could make anything out of pasta, what would it be? A miniature of your cat? Edible post-it notes? A chess set?
Well start sketching, because you can. 3D printing is here to make your pasta dreams a reality.
Every year, Barilla, the world’s biggest pasta company, hosts a competition to create innovative new pastas for their 3D pasta printer. This year they received 1,300 design proposals, and are still in the midst of testing them out. But consider this past winner, Lune, a hollow moon-like sphere with crater-shaped holes for sauce to peek through. Or a pineapple-shaped pasta in development at the Barilla lab, with small holes to soak in sauce.
“It’s something you can’t really imagine,” says Jacqueline Delgado, the business manager of Blu 1887, Barilla’s food innovation company. “There are so many flavors and shapes that you don’t realize you are eating pasta. It’s hard to explain in words.” Blu started to experiment with 3D printing seven years ago, and were able to build their own printer in 2015.
Pretty shapes are part of the fun, but the 3D-printed pasta is ultimately about innovation: using software to sculpt forms that could never be made by hand or mechanical extruder. The technology gives you the freedom to think about how geometry affects flavor and texture, and how a pasta shape interacts with a sauce.
Here’s how it works: First you download your 3D model into the printer (it’s the size of a small fridge), then load printer cartridges with semolina dough. And then you press print. The printer builds the pasta layer by layer, with a nozzle that moves along the X, Y and Z axes, spitting out the dough in a steady stream. It takes two to three minutes for the printer to make nine pieces of pasta.

“We want to astonish people,” Delgado continues. “To give them pasta that can’t be done with hands. For example, for one customer we made a pasta in shape of the Eiffel Tower. We want to create totally new experiences with pasta: it can be finger food, even sweet.” She sees opportunity for custom pastas at special events like weddings, and in fine-dining restaurants.
The most interesting design proposal Delgado has seen? “Octopus!” she bursts in laughter. “Think about it, how it would look, if you would put it in a soup, and its arms would be all around! When you start dreaming—there are so many things you could do with pasta.”
Pasta is just one application for 3D printers and food. The first 3D restaurant in the world, Food Ink, is serving printed fine dining dishes like lobster-shaped pastries filled with lobster. And as printing technology becomes more affordable, anyone can indulge their fantasies of sculpting a hummus castle, then laying siege with with pita chips.
