Concrete printing startup Kizuki made it with builder Onocom using a custom Cobod 3D-printer, enabling printing from half a metre below ground to a height of 7m. They used 39 cu m of material to get a total printed area of 50-sq-m, with a four-person team operating the printer in temperatures ranging between 10°C to over 35°C.

The design is inspired by caves, with 3D printed arches printed longitudinally, slabs for the roof and floor, and interior elements printed to extend the curved geometry. A press release sent to GCR said the project showed that 3D-printed reinforced concrete can act as an alternative to traditional timber construction because it met seismic requirements in earthquake-prone regions. Kizuki now plans to create more 3D-printed structures with broader applications. The cave-inspired architectural concept is repeated throughout the building Rika Igarashi, Kizuki’s chief executive, said: “Based on the knowledge gained through our recent residential...
