Engineers at IHI Aerospace and Yamagata University, in collaboration with Nordson EFD Japan, are working on an innovative project: 3D printed sushi intended for space tourists. This initiative arises from the increasing intersection of food technology and space exploration.
Space tourism is a luxury venture, with costs ranging from $250,000 for a brief flight to astronomical sums exceeding $20 billion for longer journeys. As such, it’s expected that even the onboard dining experience matches this high-stakes investment. The idea of 3D printed sushi caters to this expectation, leveraging the dish’s global popularity while also addressing the challenges of weight reduction in space.
To create this unique form of sushi, the project emphasizes simplicity by using fresh ingredients coupled with balanced flavors and appealing presentations. Instead of relying on traditional sushi-making methods, the engineers opted for food paste, inspired particularly by uni (sea urchin) paste, which is more shelf-stable than its original form. However, a major challenge remained: how to deposit this paste without damaging the rice base.
Nordson EFD Japan was enlisted to tackle this issue, using their PICO Pulse jet valve system, which enables precise deposition of materials. This technology was integral to the goal of providing four types of 3D printed sushi: uni, white fish, crab, and shrimp, while avoiding any flavor residue during the process.
The initial prototypes have shown promising results, being visually appealing and consistent through numerous tests, even making an appearance at a significant trade show in Japan. Besides potential use in space, the team highlighted how this sushi could benefit hospitals, nursing homes, and long-term care facilities.
Though still a concept, and with no implementations planned yet as of now, the project showcases the fascinating potential of merging 3D printing with culinary art, specifically designed for the unique environment of space. As space tourism evolves, 3D printed sushi may very well become a reality for travelers looking for gourmet experiences in orbit.
