The launch represents an important step forward for construction automation, sustainable building technology and India’s growing role in global advanced manufacturing. Tvasta, a Chennai-based startup founded by IIT Madras alumni in 2016, has been working at the intersection of robotics, automation and construction 3D printing. With Cedar, the company is now taking its technology to a global stage. The printer has been designed and manufactured in India and is being positioned for deployment across international markets, including the United States, Europe, the Middle East, Asia and Africa. ![]() At a time when the global construction industry is looking for faster, more affordable and more sustainable building methods, Cedar aims to solve some of the biggest challenges faced by developers and contractors. These include high material costs, labour dependency, long project timelines, construction waste and limited access to scalable automation. A Make in India Innovation for the WorldCedar is more than just a new construction machine. It is a strong example of Make in India moving from research and development into real-world global deployment. Tvasta’s journey began with the goal of using additive manufacturing to transform how buildings and infrastructure are created. Over the years, construction 3D printing has gained attention because of its potential to reduce build time, improve accuracy and use materials more efficiently. However, widespread adoption has been limited by high machine costs, expensive printing materials and the complexity of deploying large-format printers on actual construction sites. Cedar has been designed to address these barriers. By combining Indian engineering, AI-based material optimisation and a scalable printing platform, Tvasta and 14Trees are trying to make 3D concrete printing more practical for mainstream construction projects. ![]() What Makes Cedar Different?One of Cedar’s most important features is its portal-frame architecture. This structure makes the printer suitable for large construction sites and allows it to support projects across residential, commercial, industrial and infrastructure categories. The printer can reach up to 10 metres in printing height and has an extendable footprint of up to 240 square metres. This gives construction companies the flexibility to use it for different types of projects, including homes, offices, technical facilities, industrial structures and infrastructure components. Another major advantage is cost. Cedar offers printing volumes comparable to many existing large-format 3D construction printers, but at nearly half the capital investment. This is significant because high upfront cost has often been one of the biggest reasons construction companies hesitate to adopt 3D printing technology. ![]() By reducing the entry barrier, Cedar can help more developers, contractors and public sector agencies explore automated construction. Printing With Real ConcreteA major breakthrough in Cedar is its ability to print with real concrete instead of relying only on specialised mortar-based mixes. Many construction 3D printers depend on costly mortar materials, which can make projects expensive and limit the use of locally available resources. Cedar is designed to work with standard concrete formulations. This can reduce material costs by up to 5x, making 3D concrete printing more affordable and practical for large-scale construction. The ability to use real concrete also improves local adaptability. Construction projects across different countries and regions often depend on materials available nearby. By supporting locally sourced concrete formulations, Cedar can help reduce transportation costs, improve supply chain efficiency and lower the environmental impact of projects. ![]() AI Companion for Smarter ConstructionCedar is not just a hardware platform. It is supported by the 14Trees AI Companion, a digital platform that helps optimise material performance using local resources. The AI Companion analyses thousands of mix designs to help construction teams balance cost, strength and environmental impact. This is especially important in construction because project conditions vary widely from one region to another. Local materials, climate, humidity, temperature and structural needs can all affect the performance of concrete. By using AI to recommend and optimise material mixes, Cedar can help contractors achieve more consistent results. It also supports better decision-making by giving teams data-driven insights before and during the construction process. This combination of robotics and artificial intelligence gives Cedar a clear advantage in real-world deployment. It is not only designed to print structures, but also to help teams understand how to print them efficiently, safely and economically.

The company has worked on multiple 3D-printed building projects, including housing, educational facilities, offices and technical infrastructure. The launch of Cedar shows how Indian deep-tech startups are moving beyond prototypes and pilot projects. They are now building industrial-grade solutions that can compete in global markets. Tvasta CEO Adithya V S has described Cedar as a platform that brings together advanced manufacturing, robotics and software. The goal is to create a system that can perform reliably across different construction environments. 14Trees CEO Francois Perrot has also highlighted the economic side of the technology. According to him, construction 3D printing must not only be technically proven, but must also make financial sense for contractors and developers. Cedar has been designed with that requirement in mind. Why Cedar Matters for the Construction IndustryThe construction industry is under pressure to deliver projects faster, reduce costs and adopt greener methods. Traditional construction often involves long timelines, material wastage, labour shortages and inconsistent quality. Automation can help address many of these issues. Cedar’s 3D printing technology can reduce construction time by automating repetitive building processes. It can also improve precision, reduce dependency on manual labour and lower material wastage by placing concrete only where needed. For developers, this means faster project execution and potentially better cost control. For governments and public sector agencies, it could support faster delivery of housing, schools, community facilities and infrastructure. For emerging markets, it offers a more accessible route to advanced construction technology. The use of AI for material optimisation also supports sustainability. By improving mix designs and reducing waste, Cedar can help construction firms lower their environmental footprint. Taking Indian Deep-Tech GlobalCedar’s global deployment strategy is one of the most important parts of this launch. The printer is being positioned for markets across the United States, Europe, the Middle East, Asia and Africa. This is a strong signal that Indian startups are no longer limited to solving domestic challenges. They are creating globally relevant technologies in areas such as robotics, automation, AI and advanced manufacturing. For India, Cedar reflects the growing maturity of its deep-tech ecosystem.
