In 2013, 3D printing was already making waves. Fast forward to today, and the technology has expanded its reach into the food industry. Since the world’s first 3D-printed car in 2011 and the first 3D-printed gun appeared earlier this year, Spain-based startup Natural Machines introduced Foodini—a 3D food printer that is set to change the way we think about cooking.
Foodini is still in the testing phase, but it's close to launch. It's expected to be officially released in the U.S. in mid-2014, with a price tag of around £835 (approximately 8,000 RMB). This innovative device combines technology, art, and design into one machine. With five interchangeable capsules, it can hold different ingredients, similar to how printers use ink cartridges for various colors. Users can control the shape, size, and quantity of food through a computer interface.
To use Foodini, users first blend fresh ingredients into a paste and load them into the capsules. Then, by selecting a desired food icon on the control panel, the printer starts working. Equipped with six nozzles, it can create a wide range of dishes in multiple combinations. The machine allows users to customize the form, height, and volume of their food—whether it’s flat cookies or intricate chocolate towers, even cartoon characters on food items. However, it doesn't cook the food, so users must finish the meal themselves.
According to co-founder Cuksma of Natural Machines, Foodini could revolutionize traditional cooking methods, much like how microwaves transformed kitchens. Despite its high cost, the device has attracted interest from over 30 countries, with even Michelin-starred chefs showing enthusiasm.
Beyond home use, 3D food printing has broader implications. For instance, it brings us closer to achieving space travel dreams. NASA has taken an interest in the technology because 3D printing could help solve food storage issues during long missions. It also holds potential for addressing global food shortages. By 2050, the world population is expected to reach 9 billion, increasing the demand for food significantly. 3D printing could expand the sources of food, including unconventional options like insects, thus reshaping traditional food production methods.
Additionally, 3D food printing can cater to personalized nutrition needs, offering tailored meals for different age groups or dietary requirements. While the technology shows great promise, there are challenges, especially in China. One major issue is the limited availability of consumables. Most materials used in 3D printing today include gypsum, resins, and plastics, which are insufficient for more complex applications like printing cars. Many metal materials, such as titanium alloys, are still imported.
Another challenge is the shortage of skilled professionals. Education systems haven’t kept up with the rapid development of 3D printing. According to Lu Junshang, president of 3D Power Network, there's a gap of about 8 million 3D application talents in China. To address this, initiatives like "3D-e education" and the "3D Special Forces Training Camp" have been launched to train and develop high-level talent.
As 3D printing becomes a global focus, experts believe the government should prioritize its development. Strengthening top-down planning, integrating the industry into national priorities, and fostering talent at all levels will be crucial. Establishing industry organizations, developing standards, and promoting policy support are key steps toward accelerating the growth of the 3D printing sector.
