Technology & Products
Key Products
ACRO-IR Series (industrial robotic 3DCP system); ACRO-UR Series (mobile robotic-type 3DCP for research); ACRO-UG Series (compact gantry-type 3DCP for research); 3DCP Slicer software; 3D concrete printing construction services for buildings, civil infrastructure, and architectural structures
Technological Advantage
Proprietary mobile robotic-arm 3DCP technology (10-axis ACRO-IRT1); self-developed 3DCP Slicer software; in-house concrete material formulation achieving 50MPa compressive strength; 2K nozzle system for functional admixture mixing at point of extrusion; ability to reduce construction time and labor by over 50% compared to conventional methods
Differentiation
Value Proposition
Mobile robotic-arm-based 3D concrete printing systems that offer greater flexibility, lower setup costs, and faster deployment compared to traditional fixed gantry-type construction 3D printers, enabling on-site construction of buildings, infrastructure, and architectural structures.
How They Differentiate
Unlike competitors using large fixed gantry systems, Dong-A Robotics uses mobile robotic-arm-based 3D printers mounted on tracks or wheels, offering superior mobility, faster deployment, ability to work in confined spaces, and capability to print curved/non-standard architectural forms.
