The project of 3D printing technology in construction and architecture 3D-STAR is focused on the development of robotic equipment, capable of outpatient implementation of construction structures from suitable building materials. Within this framework, a conceptual solution of the printing robot will be developed, some parts of which will be verified on functional samples. At the same time, suitable building materials will be examined and developed and sought for optimal constructional construction principles, utilising the unique possibilities of this technology. a.
