Serendix is Japan's first 3D-printing home manufacturer, Kaito Ogata, the company's CTO, told Insider in an email.The 107-square-foot Sphere was constructed in under 24 hours, according to the company.The cute dwelling was constructed in late July over 44 hours, the company's CTO said. It was nicknamed Fujitsubo, which translates to barnacle.Inside, the single-story 527-square-foot home has one bedroom, bathroom, and living room with a kitchen.The wood roof was then built using a CNC (computer numerical control) cutter. Because almost all of the primary components of the home were built using automated tech, the startup was able to save both time and money.And to further slash construction costs, the Japanese company printed the home using a cement mix with an additive to help it harden quickly. The majority of 3D-printed homes are currently being built using some form of a concrete concoction. They were then moved and connected to the home's steel columns and foundation using a truck and crane, similar to connecting Lego pieces together. However, the company had to reprint some walls after they were broken in this moving process. California-based Azure Printed homes — which uses recycled plastic to 3D print homes — charges about $125,900 for an accessory dwelling unit of a comparable size. And stateside, it's the primary reason more startups and legacy home builders have started turning to this 3D printing homebuilding technology. Proponents of the tech say the more it becomes prevalent, the more it can help cut the time, materials, labor, and cost needed to construct a home.But this could soon change. At the end of October, the company will begin fulfilling an order for six of these units, Ogata said.
