Experimental Development of 3D Printing Using Cement Composites

Original language description

The research of 3D printing of cement composites is carried out in cooperation with the Technical University of Liberec, the Klokner Institute of the Czech Technical University in Prague and the company Červenka Consulting s.r.o. The research deals with the use of 3D printing of cement composites in architecture and construction. The research develops original equipment for 3D printing of mixtures with cement-based binders, including the original design of printing mixtures and original software for printing data processing and machine control. The ambition of the project is to develop equipment that can be used for in-situ printing of building elements and to develop such procedures that would enable the implementation of a printed multi-storey building. The print is focused on vertical and horizontal load-bearing structures. The vertical structures will be printed in the final position, the horizontal structures will be printed on the construction site in the form of prefabricated parts, retrofitted by a crane on the pre-printed walls of the building. The shape and static solution of vertical and horizontal elements of the supporting structure is optimized for 3D printing technology with a focus on minimizing material consumption in accordance with current requirements for sustainable construction, saving non-renewable raw materials and energy savings. This leads to the use of thin-walled constructions with a print width of 20 to 50 mm. At the same time, design procedures for these types of structures and implementation of 3D printed elements into non-linear Atena software, designed for advanced modeling of concrete structures and developed by Červenka Consulting s.r.o. At present, a Test-Bed is in operation, intended for testing the print head and development of printing mixtures, with a printing space of 3 x 1 x 1 m. Stability and other properties and tuning of design procedures so that in the future they allow safe verification of designed structures in terms of their static function. Part of the research is the study of printing logistics on site and a comprehensive design of the entire system from the mixture to the printed structure.
