The M3DUSA PRINT HEAD uniquely enables the use of standardized fresh concretes (according to EN 206 standard up to 14 mm aggregate size), standardized dry concretes (according to EN 206 standard up to 8 mm aggregate size), RC concretes (rounded and angular aggregates), standard lightweight concretes (bulk density 1.6), and standard dry mortars for 3D printing. Furthermore, the system has been designed to allow the M3DUSA print head to be adapted to various industry-standard 3D printers, including 6-axis robots, gantry printers, Scara printers, etc.
