How was the idea born?
Shahaf PY was born out of the development department of its parent company, Shahaf Stone & Marble, a company with many years of experience in creating advanced manufacturing solutions for architectural and design elements in the construction industry. Through hands-on work in the field and deep observation of industry trends, it became clear that the future of construction requires moving away from traditional manufacturing toward smarter, more flexible, and scalable solutions.
The enormous potential of 3D concrete printing led to the establishment of Shahaf PY as an independent company focused on developing a new generation of printing systems. The company develops a holistic technology that integrates material, software, and hardware to enable precise, fast, and high-quality production, anywhere and under any conditions.
Shahaf PY’s vision is to lead advanced construction and enable its customers to build smarter, faster, greener, and with significantly higher efficiency.
What is the need for the product?
The global construction industry is facing a multi-dimensional crisis: rising demand for infrastructure and housing, severe skilled labor shortages, increasing material costs, and heavy environmental pressure.
In this reality, 3D concrete printing is shifting from an experimental trend to a genuine strategic solution. It breaks the direct link between complexity and cost, offering nearly unlimited design freedom at no additional expense, while delivering minimal material waste, reduced dependence on manpower, and lower on-site risks.
At the heart of Shahaf PY’s solution lies the ability to print with standard local concrete, without the need for special mixes. The system enables every construction site or factory to produce on its own, with full control from material to final product.
The technology also shifts the focus of R&D to the customers themselves, as we develop the R&D in close cooperation with veteran strategic partners in the fields of energy, infrastructure, defense, aviation, and maritime. Shahaf brings the technology and innovation, while the partners bring domain knowledge and precise needs, enabling new manufacturing processes and far more advanced, intelligent products than traditional methods can achieve.
Thus, alongside residential construction, the technology is also used for producing molds, roads, complex infrastructure elements, and defense applications.
How is it changing the market?
Shahaf PY is bringing a profound change to the market, one that begins at the technological level and ultimately redefines the entire value chain in the construction industry. The transition from experimental printing to a true industrial solution turns construction sites and factories into real-time smart manufacturing hubs. Instead of slow, labor-intensive, mold-dependent processes, a digital, precise, and flexible process emerges, one that responds to needs instantly.
The core change is the shift from a rigid production model to a completely dynamic one. Instead of “production for inventory” and dependence on expensive molds, on-demand manufacturing becomes possible, fully synchronized with project progress. This results in significant savings in time, space, and costs, while unlocking design possibilities that were previously unfeasible.
The fundamental difference between standard 3D concrete printing and Shahaf PY’s solution is what makes this transformation possible: while most existing solutions rely on expensive, proprietary mixes and closed systems requiring high expertise, Shahaf PY enables the use of standard delivered concrete in open, flexible systems. The printers are not limited to a single robotic platform and can be adapted to a wide variety of configurations according to need.
How big is the market for the product and who are its main customers?
The 3D concrete printing market is developing rapidly, moving from an experimental niche to a major industrial sector. It can be divided into two main segments: printing services and products, and equipment and hardware.
The services and printed products market is currently estimated at $3.5-4 billion (2024-2025) and is growing at an exceptional rate of 100%-115% annually in aggressive scenarios. Forecasts indicate the market will exceed $40 billion by 2030.
The printer and hardware market is currently smaller ($500-800 million) but is expected to grow at a similar pace as demand for printing services increases. Shahaf PY is well positioned in the equipment segment thanks to its technology that significantly lowers adoption barriers.
Its key target customers are:
- Construction and Infrastructure Companies seeking to shorten timelines and overcome labor shortages.
- Government and Defense Organizations that are focused on rapid response, logistics, and deployment in the field (temporary infrastructure, fortifications, disaster recovery).
- Precast Manufacturers and Design Firms looking to replace expensive mold-based production with flexible, customized manufacturing of urban furniture, architectural elements, and infrastructure components.
Does the product exist already?
Shahaf PY’s product is already operational in the field. The company runs an active production floor with multiple robotic printing systems working in parallel, manufacturing real products for the market. This environment serves both as a production line and as a living development lab where every component – material, software, and hardware – is tested, improved, and adapted to real-world conditions.
At the same time, the engineering teams are developing the next generation of autonomous, precise, and user-friendly systems, with the vision of making complex 3D concrete printing as intuitive as sending a file to a desktop printer.
he material exists, but our way of making it is the revolution. We have successfully moved past the laboratory phase and begun semi-industrial-scale manufacturing. This is a pivotal milestone that enables us to secure our first sales to end users and start strategic partnerships with major global market players.
Who are the main competitors in this sector and how big are they?
The 3D concrete printing market is still young, but several international players already stand out. Most have demonstrated impressive capabilities in specific projects, yet most solutions still rely on closed systems, proprietary mixes, or limited robotic configurations. This is where Shahaf PY’s differentiation lies:
- COBOD (Denmark) – Strong in hardware sales, known for large gantry systems and collaborations with PERI and GE Renewable Energy.
- ICON (USA) – Highly funded and publicized, leading large residential projects and NASA collaborations. Uses proprietary Lavacrete mix and a closed system.
- Apis Cor (USA) – Known for compact robotic systems and the famous Dubai municipal building project. Offers good mobility but with limitations in scale and industrial applications.
While most competitors focus primarily on house construction, Shahaf PY operates in both residential building and in infrastructure, defense, energy, and advanced industrial applications.
