The Biggest 3D Printer Adam Savage Has Ever Seen!

Adam Savage heads out to ICON’s testing ground to check out their colossal 3D printers that can spit out entire concrete structures—yes, full-on houses. He dives into how reinforced concrete is extruded layer by layer and even gets a sneak peek at ICON’s next-gen, multistory printer.

Along the way he chats build times (spoiler: faster than you’d expect), tech challenges and real-world potential. No sponsors here—just pure Adam enthusiasm for groundbreaking house-printing innovation.
