Construction 3D Printing for high-risk sites: the Ukrainian proposal to protect personnel
3D concrete printing can become a safety tool on dangerous construction sites. Research from the Kyiv National University of Construction and Architecture proposes an integrated system that combines Construction 3D Printing, prefabrication, autonomous vehicles, and assembly robots to drastically reduce human presence in high-risk areas.
The study, signed by Oleg Povolotskyy and published in 2026 in Transfer of Innovative Technologies, stems from Ukraine's experience under martial law. The approach shifts the focus of additive technology from productivity and geometric freedom to a more concrete parameter: minimizing operations that require physical presence in exposed areas.
An integrated system, not just a printer
The proposed model does not simply bring a 3D printer to the construction site, but articulates an entire production chain distributed between safe zones and high-risk areas.
The system involves the production of protective elements and modules in mobile plants located at a safe distance from the intervention area. The components are then transported by autonomous vehicles and positioned with robotic systems. Personnel intervene only for operations that cannot be automated, reducing exposure time.
Povolotskyy, associate professor at the Department of Construction Organization and Management of KNUBA, assigns a central role to prefabrication. Structural elements are produced in a controlled environment, where automation and quality control are more effective.
- Integrated system: 3D Concrete Printing + prefabrication + autonomous vehicles + robots
- Production in safe zones, robotic assembly in high-risk area
- Objective: reduce human presence in dangerous construction sites
- Theoretical-design study, not experimental demonstration
Nature of the study: analysis and technological proposal
The research does not present an already operational robotic construction site, but formulates an operational model based on existing technologies.
It is essential to clarify that the study published in 2026 is mainly a work of analysis and technological proposal. It does not document an already functioning robotic factory nor does it provide experimental data on risk reduction, labor, or construction times.
The strength of the work lies in formulating a model in which 3D Concrete Printing, prefabrication, and robotics are designed together from the start. This systemic approach contrasts with the use of the printer as an isolated machine, typical of many current applications.
Architecture of the proposed system
The starting point is to transfer as much work as possible out of the dangerous area, keeping only the final assembly activities on site.
Povolotskyy proposes a specific configuration of mobile printer called “printer tower-type” with SCARA kinematics. This solution would allow greater flexibility in the positioning of production plants.
The system is structured on three operational levels. Building Component Manufacturing (BCM) produces individual elements in a protected environment. Large-Scale Prefabrication (LSP) assembles these components into complete modules. Finally, autonomous robotic systems manage transport and final installation.
The study fits within the context of the ISO/ASTM 52939:2023 standard for qualification in additive manufacturing in construction.
Implications for the industry
The Ukrainian approach redefines the value of Construction 3D Printing: not only economic efficiency, but protection of people.
The research opens a different perspective on additive technology in construction. While most developments focus on construction speed and geometric complexity, the KNUBA model prioritizes personnel safety.
This paradigm shift could affect not only conflict zones, but also construction sites in extreme environments: contaminated areas, seismic zones during emergencies, installations in prohibitive climatic conditions. The reduction of human presence becomes a primary advantage, not a secondary one.
The work also identifies the problems still to be solved to make the system operational. The transition from theoretical proposal to practical implementation will require significant developments in robotic coordination, autonomous logistics, and standardization of prefabricated components.
The publication in Transfer of Innovative Technologies nonetheless marks a milestone: Construction 3D Printing can be rethought as a protection technology, not just a production one.

Q&A
What is the main objective of Ukrainian research on 3D printing in construction?
The goal is to minimize the physical presence of human personnel in high-risk construction areas. The proposed system shifts focus from mere productivity to operational safety through automation.
How does the integrated system proposed by the study work?
The model combines Construction 3D Printing, prefabrication in safe zones, autonomous vehicles for transport, and robots for final assembly. Structural elements are produced away from danger and assembled on-site without human operators.
Does the research describe an already operational robotic construction site?
No, the study published in 2026 is a theoretical-design analysis and does not document an existing functioning robotic factory. It provides no experimental data on risk reduction or construction times, but formulates an operational model based on existing technologies.
Who conducted the study and where was it published?
The research was authored by Oleg Povolotskyy, Associate Professor at Kyiv National University of Construction and Architecture. The study was published in 2026 in the journal Transfer of Innovative Technologies.
What role does prefabrication play in this safety model?
Prefabrication plays a central role by enabling structural elements to be manufactured in controlled, safe environments away from the intervention zone. This approach enhances automation and quality control effectiveness prior to on-site transport.
