It’s Alive! 3D Printed Food Which Grows Itself

Edible Growth 3D-printed food by Chloé Rutzerveld

Food designer Chloé Rutzerveld has developed a concept for “healthy and sustainable” 3D-printed snacks that sprout plants and mushrooms for flavour.

Rutzerveld‘s Edible Growth project consists of 3D-printed shapes containing a mixture of seeds, spores and yeast, which will start to grow after only a few days.

“Edible growth is exploring how 3D printing could transform the food industry,” she says in the movie. “It is about 3D printing with living organisms, which will develop into a fully grown edible.”

Each of the basket-like 3D-printed structures, which Rutzerveld presented at Dutch Design Week 2014, contains an edible centre of agar – a gelatinous substance that enables the seeds and spores to sprout.

As the plants and mushrooms grow, the flavour also develops, transforming into what Rutzerveld claims is a fresh, nutritious and tasty snack after only a few days.

“As it comes out of the 3D printer you can really see the straight lines of the technology,” she says. “But as it develops, you can see organic shapes. You can see the stages of growth and the development of taste and flavour.”

The aim of the project, which Rutzerveld developed in collaboration with the Eindhoven University of Technology and research organisation TNO, was to investigate ways that 3D printing could be used in the food industry.

“By 3D printing food you can make the production chain very short, the transport will be less, there is less land needed,” says Rutzerveld.”But also you can experiment with new structures. You can surprise the consumer with new food and things that haven’t been done before.”

In particular, Rutzerveld wanted to find a way that 3D printers could be used to create fresh and healthy food at home.

“A lot of people think industrialised production methods are unnatural or unhealthy,” Rutzerveld says. “I want to show that it doesn’t have to be the case. You can really see that it’s natural. It’s actually really healthy and sustainable also at the same time.”

However, Rutzerveld’s project is still at the research and development stage and she admits it will be a long time before anyone is able to 3D-print her snacks at home.

“It will take at least another eight to ten years before this can be on the market,” she concedes. “The technologies really need to be developed much further.”

3D printed smoothies!

Flavour of the week: 3D Printed smoothies!

http://3dprint.com/23223/3d-printing-with-banana/

The second attempt appears significantly more palatable.

Bananas have been referred to as “the perfect food.” Not only are they rich in nutrients but, in terms of form, they exemplify the perfect self-contained packaging and delivery systems. Who doesn’t enjoy peeling a banana and admiring its ingenious design? Not content to leave well enough alone,3DigitalCooks, a website devoted to making and reporting “digital gastronomy news” has conceived of a new way to approach the banana.

Printing With Bananas, 3DC’s recent project, combines the smoothie fad with 3D printing. After extolling the nutritional virtues of the banana, 3DC’s banana-based blog entry describes the process through which they 3D printed with bananas. Probably not surprisingly, the consistency of the banana, although ideal for smoothies, proved problematic. Extruding the pureed banana was one thing. Even printing it layer by layer was not so challenging, but getting the end result to be anything but a puddle of formerly firm banana was difficult.

3DC solved the consistency problem by consulting the experts at the FoodDev section of Reddit, who recommended adding a thickener — potato starch proved to be the best — to the pureed bananas, ensuring that the printed end result would take a form other than unmanageable (and, frankly, unappealing) liquidy mess. However, the tendency of bananas to turn brown when exposed to air needed to be confronted, so the team added orange juice to counteract the darkening. The results were less than impressive and we’re wondering if nobody on the 3DC had a grandmother who could recommend lemon juice.

In any case, consistency issues were surmounted and the 3DC team got to work 3D printing. They experimented with temperatures and the amount of potato starch to water and orange juice proportions, and struggled over unsightly lumps and discoloration. Their solutions are provided at the end of the blog, although, clearly, anyone willing to take up the torch and 3D print their own banana-flavored delicacies is encouraged to experiment with recipes, temperatures, and consistency.

Although the “Printing With Bananas” blog entry doesn’t provide information about the equipment 3DC uses to produce their 3D-printed digital edibles, their site explains that they use PLYUMP, an open hardware peristaltic extruder, which is designed for use with 3D printers. Luis Rodriguez Alcalde, founder of 3DigitalCooks, describes the evidently aggravating process of finding the best extruder for the team’s purposes. Unable to find a suitable existing extruder, he set about designing and creating his own; the PLYUMP currently in use is version 0.43.

In addition to 3D printing bananas, 3DC’s collaborators, from Amsterdam to Portland, have shared their own digital edibles projects. There’s the “Bot-B-Q,” an open source 3D printing barbecue from Frankfurt, Germany, “Laser Cooking” using a laser cutter as a dry-heating cooking device from the Fukuchi Lab in Japan, and from Texas, 3D printed “Piq Chocolates” with personal inscriptions, plus a range of other links to digital food prep sites making 3DC definitely worth perusing even if the projects aren’t feasible due to your own limitations — equipment, palate, or otherwise.

Have you ever tried 3D printing with banana puree?  How about any other foods?  Let’s hear your thoughts in the 3D Printing & Bananas forum thread on 3DPB.com.
