Technology & Products
Key Products
["REbuild 1: A mobile 3D printer for small-scale architecture and prefabrication.","REbuild 2: A large-scale gantry system for functional buildings and large structural elements.","Proprietary 3DCP Printing Head: Features an internal mixer, vibrator, and stamping screw for high-quality extrusion.","Automated Reinforcement System: A module for the automatic placement of composite reinforcement during the print cycle.","Proprietary Concrete Mixes: Specialized cementitious materials optimized for high-speed 3D printing."]
Technological Advantage
High-speed extrusion capabilities (up to 300 mm/s) combined with a proprietary 'quick-change' nozzle system and a stable gantry architecture that ensures high precision for large-scale structures.
Differentiation
Value Proposition
Significantly reduces labor costs and construction timelines by automating the entire building process, including the complex integration of structural reinforcement which is typically a manual bottleneck in 3D printing.
How They Differentiate
Proprietary automated reinforcement system (patented) that integrates structural support during the printing process, combined with high-speed extrusion (up to 300 mm/s) and specialized concrete mixes.
