Meet CryoFab | 2026 President's Innovation Challenge Ingenuity Award Winner

Today over 100,000 people in the US are waiting for organ transplants. One of the biggest barriers is vascularization because without internal channels engineered tissue can't deliver oxygen and nutrients and it fails. Our project Cryopab approaches this problem using an unexpected material ice. We built a bespoke 3D ice printer from scratch. custom extrusion, a peltier cooling system down to -45° C, and our own tool path logic. And we made it work. Now, here's why that matters. Ice can create precise internal channel geometries inside soft materials and then simply disappear. No toxic residue, no extraction, just the channels you need exactly where you need them. This opens up new ways to fabricate internal structures with long-term potential in tissue engineering where vascular networks remain one of the biggest unsolved challenges. Cryopab shifts fabrication from building permanent structures to designing what can disappear to make life possible. We are Cryopab.
