Wealth on Instagram: "A 3-D home can take full-force sledgehammer strikes without cracking, and that’s not an accident. 😳 🏠 3D-printed homes are built layer by layer using specialized concrete mixes engineered for high compressive strength, impact resistance, and long-term durability. Instead of hollow framing or stacked blocks, the structure forms a continuous load-bearing shell that spreads force across the entire surface. Many designs also integrate steel reinforcement, fiber additives, and
