Скачать или смотреть 3D Printing Houses: Materials, Speed, and Structural Integrity

3D printing concrete fundamentally changes construction physics. We analyze the rheological requirements—thixotropy, pumpability, and buildability—that enable layer-by-layer deposition. Explore the structural challenges of interlayer bonds and the integration of reinforcement systems like fiber-reinforced concrete and post-tensioning. We compare Gantry versus Robotic Arm systems, quantify current volumetric printing speeds, and detail how insulation and utilities are integrated into printed wall cavities. Finally, we examine the path to code compliance and scalability for infrastructure applications.
