The ‘uncanny valley’ of 3D printed food could be a natural fit for astronauts


In popular perception, food is something of the holy grail of 3D printing: printing your own dishes is like being able to use a real-life Star Trek food replicator or a Fifth Element-style meal packet. We’re not there yet, but Wired has profiled the Cornell University Fab@Home project’s ongoing efforts to make viable 3D printed foods. Unlike projects that focus on molding existing materials like chocolate, Fab@Home uses gel-like substances that can be combined with other materials (including artificial flavoring) to mimic the taste and mouthfeel of many different foods.

While the flexibility and precision of 3D printing could make it a hit in Earth-bound molecular gastronomy, the ability to make small, varied portions of food is…
