Robotic 3D Concrete Printing

Wildfire-resistant home design depends less on walls than on roof, eaves, and windows. Inside the 3D-printed Walnut, CA ADU rewriting fire-survival rules.

How Builtech's Walnut, CA project mapped the permit pathway for fire-resistant 3D-printed concrete ADUs.

The first U.S. 3D-printed fire-resistant ADU shows printed walls are the easy part. Roofs, eaves, and windows decide whether the home survives a wildfire.

Fire-resistant 3D-printed ADUs are California's WUI building-code answer. Here's why the next 100K permits should be non-combustible by default.

Compare 3D-printed concrete, mycelium, and compressed earth blocks for fire-resistant ADUs. See why Walnut, CA's first wood-free 3D-printed ADU chose concrete.

L.A.'s tight backyards are forcing 3D concrete printers to shrink, mobilize, and rethink ADU construction — here is why footprint, not speed, now wins.

Compact modular robotic 3D printers let contractors print concrete ADUs in tight residential backyards. Here's why the form factor changes the game.

Concrete walls. Steel roof. No wood, no nails. See how Builtech's two-material home thesis makes 3D-printed ADUs survive California wildfires.
