Portrait of Emmanuel Roy: A Pioneer in the Use of Geopolymer in 3D Printing

Today, we spotlight Emmanuel Roy, a prominent figure in the field of 3D concrete printing in Canada. His career stands as a beacon of inspiration and innovation, particularly highlighted by his use of geopolymers in 3D printing.

Emmanuel has collaborated closely with our American partner, Geopolymer International. He shares with us his in-depth understanding of polymer materials and his assessment of our 3D concrete printer, the MaxiPrinter. His insights into the nuances of 3D printing with geopolymers have not only enriched the technical capabilities of the MaxiPrinter but also contributed significantly to the advancement of 3D printing technology in the construction industry.



According to him, professionals in 3D construction possess a unique mindset. They must simultaneously have a broad and detailed vision, a quality that stems from a rich and diverse background. This includes exploring different technologies, life perspectives, and construction methods. For Emmanuel, construction is not just a profession; it's an expression of human existence.

He also emphasizes the importance of having a deep understanding of human nature and our environment to excel in this field. With varied experience ranging from plumbing to electricity, and from carpentry to plastering, Emmanuel has always sought to push the boundaries of the conventional, especially in Canada where thinking "outside the box" is not as widespread as in France.

Emmanuel's experience with concrete and various materials revealed that traditional concrete was not ideal for printing. This realization led him to collaborate with Geopolymer International. Together, they discovered the potential of geopolymers, a material still in development, but promising for 3D printing.



One of the major advantages of geopolymers is their exceptional strength. They are waterproof, flood-resistant, and can even withstand extreme temperatures like forest fires, thus protecting structures from any damage. Additionally, geopolymers demonstrate remarkable durability in saltwater, possess anti-ballistic properties, and do not require cold joints, easily adhering to multiple surfaces.

Emmanuel highlights the economic and ecological aspects of geopolymers. Their production requires ten times less energy than traditional concrete and can be made from local resources, significantly reducing the carbon footprint. This makes geopolymers not only an innovative choice for construction but also a sustainable one, aligning with the growing global emphasis on environmental conservation and responsible building practices.


Regarding our 3D concrete printer, the MaxiPrinter, Emmanuel considers it a relevant alternative to gantry systems (portal 3D printers). It offers more freedom due to its mobility, speed, and compact size. The MaxiPrinter also allows for the construction of multiple floors, as the printer can be hoisted to the next level. It provides impressive flexibility, capable of printing with various materials and adapting to different projects, whether traditional or futuristic. The ecological aspect of 3D printing, particularly with geopolymers, is also a major advantage, significantly reducing waste and carbon footprint.


Emmanuel's encounter with Constructions-3D marks a revolution in the field of construction. His journey, vision, and collaboration with innovative materials like geopolymers open up exciting new prospects for the future of 3D construction. New projects are already underway with the MaxiPrinter. Stay connected to follow the incredible advancements!
