Dong-A Robotics demonstrates robotic 3D concrete printing at Hoban construction pavilion in Seoul

Dong-A Robotics presented its robot-based 3D concrete printing (3DCP) technology at the Hoban Shared Growth + Construction Special Pavilion, part of Korea Build Week and NextCon at COEX Seoul, running August 5 to 8, 2026. The system uses an industrial robotic arm to deposit concrete layer by layer to build up structural forms. The company says the process largely eliminates formwork fabrication and installation, cutting material use and construction time versus conventional methods, and that it can render complex, non-standard geometries with precision.

Construction 3DCP sits outside AMPulse's usual metal and polymer coverage, but the adoption logic tracks the same labor-shortage and productivity pressures driving automation elsewhere in Korean manufacturing. Formwork-free deposition is the same value proposition pursued by ICON, COBOD, and Apis Cor abroad, and a domestic entrant signals the category reaching Korea's construction sector rather than staying an imported technology. Dong-A Robotics frames the pitch around its robot control expertise and field construction know-how, positioning 3DCP as one automation product within a broader smart-construction lineup rather than a standalone bet.

The showcase is a trade-show demonstration inside a builder-sponsored pavilion, not a disclosed commercial contract: no build volume, throughput, cost, or named project has been released, so the technology's readiness for structural, code-compliant construction work remains unverified.
