3D-printed concrete now available in colour

Sustainable & colourful

3D concrete printing offers a more sustainable alternative to traditional formwork concrete. Because the 3D printer applies material only where needed, the products are 40-60% more durable. On top of that, 3D concrete printing offers more freedom of form. This is because the object no longer needs to be made from a solid piece of material.


And so from now on, these products are also available in various colours. This allows us to personalise our orders even further.

World record: Qatar has tallest 3D printed tower

Challenging schedule


The project was complex for several reasons, including the challenging schedule leading up to the expo opening, and because Witteveen+Bos as designer and constructor, and Saint-Gobain Weber Benelux as 3D printing expert and producer, took this record attempt as an opportunity to further innovate the 3D concrete printing technology.


The schedule was driven by the expo opening and the logistical challenge of transporting all elements by boat from the Netherlands to Qatar. Through intensive and clever collaboration, they managed to achieve a very short lead time: from the initial design idea to realization and shipping within two months.


Futuristic design


The design pushes the boundaries of 3D printing technology. The interrupted circular structure and the characteristic 30-degree inclination are eye-catching. To achieve this futuristic design, optimal use was made of the advantages of 3D printing technology. A total of 85 unique building blocks were designed. Each concrete element was individually printed, and material was only printed where necessary for strength. Furthermore, the blocks have a hollow structure.


The result is a 3D-printed tower, consisting of ten layers with eight or nine blocks each, creating a structure measuring 13 by 13 meters with a height of 12.4 meters. After assessment, the Qatari tower has been recognized as the Guinness World Record for the ‘tallest freestanding 3D-printed concrete structure.’


Marijn Bruurs, 3D concrete print expert at Witteveen+Bos: ‘This record that we achieved together with Qatar is very valuable. Especially because we have been able to apply techniques in practice that can also be used on a broader scale, for example in housing construction.  With the 30-degree inclination and interrupted circle in the design also expand the structural and architectural possibilities of 3D concrete printing.’


Peter Paul Cornelissen, Business Unit Manager 3D Printing, Weber Benelux: ‘A project like this is ideally suited to be 3D printed with concrete. This has everything to do with the extremely short lead time, the number of unique shapes, and the structural properties of the material used. To guarantee the structural properties of the individual elements, Weber has developed a unique Quality Framework. This allows the agreed quality to be delivered with short lead times and large volumes, which is essential for any structural construction.’

Weber develops eco mortar for 3D concrete printing

Because a 3D printer only applies material where necessary, 3D printed products are on average 40 to 60% more sustainable than traditional formwork concrete products. In addition, the new concrete mortar uses considerably less cement in production. This, of course, without compromising Weber’s high quality standards and delivery reliability.


Weber 3D eco is the next step for the company to provide sustainable solutions for the construction sector, including popular inclined stairs, circular outdoor furniture, entrance protections, and other custom solutions.


“Our continued commitment to innovation and sustainability has led to this remarkable achievement,” says Peter Paul Cornelissen, Business Unit Manager Weber. “With this newly developed mortar composition, we reduce our cement consumption by almost half. In this way, we contribute to a cleaner future for the construction industry and the environment.”


Weber continues to be committed to providing innovative solutions that not only meet the needs of today but also contribute to a more sustainable tomorrow. All of this supports Saint-Gobain’s global goal of ‘Making the world a better home.’

Three major pillars in 3D concrete printing: Sustainability, construction automation and freedom of form

3D concrete printing. A relatively new technique with great potential for the future of construction. “Especially with the climate crisis, the large replacement and renovation task and the labor shortage we are facing,” says Pieter Bakker, 3D printing project leader at Saint-Gobain Weber Beamix.


“We are therefore constantly looking for opportunities to become more sustainable and thus have a positive environmental impact on and in our environment.” According to Pieter, smarter construction, including through parametric design, is the solution. “We also apply that within our 3D concrete printing technology.”

Three major pillars

At Saint-Gobain Weber Beamix, the entire development of 3D concrete printing rests on three major pillars: sustainability, automation of construction (with process optimization as a goal) and freedom of form. “In terms of sustainability, we are looking beyond making concrete more eco-friendly. With 3D concrete printing, we have a technique that allows us to use even less material: less concrete, no reinforcement, no formwork. And because the process is largely automated, we can shorten delivery times and respond to the scarcity of skilled workers. In line with this is process optimization, where time and error reduction play a major role.” The third pillar, according to Pieter, is freedom of form. “After all, parametric design is a technical and very important expression of the ease of form freedom, but also the ability to generate ‘more exotic’ shapes plays an important role in this.”

Slope stairs

“A slope stairs, perhaps not the sexiest structure, very clearly demonstrates all the advantages of parametric design, immediately bringing out all the benefits of 3D concrete printing,” says Pieter. “Based on the relevant dimensions, we can design a talus staircase without drawing or calculation, which can be printed the next day and delivered within three weeks.”


The slope stairs is one of the products that Saint-Gobain Weber Beamix is fully marketing within concrete printing. “We are past the pioneering phase, have already realized about 50 stairs in the Netherlands and within the rest of Europe and have now received approval from ProRail, Rijkswaterstaat and several municipalities.”

Without drawing or calculation, we can design a slope stairs, which can be printed the next day and delivered within three weeks.Without drawing or calculation, we can design a talus staircase, which can be printed the next day and delivered within three weeks.

Most sustainable bicycle bridge

A lot more complicated than slope stairs or other fairly standard concrete products such as sewer manholes, are the 3D printed bicycle bridges rolling out of Weber Beamix’s print factory in Eindhoven. “In collaboration with BAM Infra and Province of Noord-Holland, who have really embraced our innovation, we installed four 3D printed bicycle bridges at the N243 earlier this year.

As a construction team, we went through all phases, from sketch to execution, approaching the project with the same three pillars: how can we do this sustainably, fully automated and with as little material as possible, and of course in the context of freedom of form.” This involves four bridges with different arches and dimensions, all realized from the same parametric model. It shows that within certain parameters, a lot really is possible.

Sustainable and digital innovation together

It may be obvious: 3D concrete printing fits a sustainable future. “We have already taken many steps but we are not there yet,” says Pieter. “Governments and industry will have to continue to innovate together to overcome the climate crisis. I therefore invite them to explore and take that step with us.”

Concrete Design Masterclass lets students 3D print with concrete

The Concrete Design Competition is organized biannually in Belgium, Ireland, Germany, Austria and the Netherlands. By rotation, one of the participating countries is the organizer and host country for the joint International Concrete Design Materclass. For the 11th edition of the Competition 2023-2024, it is the Netherlands’ turn. In the Netherlands, participants will get to work in our 3D concrete printing factory in Eindhoven.


Here they will work on their design and various master classes. On the last day, the participants actually get to work in the concrete printing factory.


3D-concrete printing in Masterclass


We will make our knowledge and facilities available for a week in August 2024 so that students can learn to design for the 3D concrete printer. The Master Class under the guidance of bureaubaker is also meant to be a hands-on workshop where the students themselves make the molds for the designs in concrete. In this Master Class, in addition to designing for the 3D concrete printer, molds will be made from textiles.

“The formal language of both textile molds and 3D printing can be called special, perhaps even organic, and can therefore be explored perfectly well together by the students.”

Siebe Bakker – bureaubakker


In the printing plant at Weber, the printing process is completely digitally controlled. And with these innovative techniques we have been able to realize many projects in recent years. The first printed bicycle bridge in Gemert was in fact the starting signal for a whole series of printed bridges in Nijmegen, Steenwijkerland and now for the province of North Holland, among others. Various bicycle and pedestrian bridges are also being printed. In addition, of course, we cannot forget the Milestone project, consisting of about 5 printed houses, the first of which has already been inhabited. And in 2022 we even made it to the Guinness Book of Records with the highest printed object in the world (12.10 meters), the 3D printed version of the Burj al-Hamam was on display at the Floriade in Almere.

Student design contest


In the Netherlands, the design competition for architecture, civil engineering, interior design and art students is organized by Tektoniek, platform for concrete architecture. “We challenge students to design with concrete, to explore the unique and aesthetic properties of this material within the theme of this edition ‘Presence’. This challenging theme addresses how the material can impart a certain tactile experience to the form of a space or object in the built environment,” said Cindy Vissering of Tektoniek.


The students who are allowed to attend the Concrete Design Masterclass are the winners of the Concrete Design Competition from the five participating countries. Each country organizes its own similar competition. In the Netherlands, in addition to participation in the Master Class, prize money is available to the winners. An expert jury evaluates the entries and the winners are announced in June. The Dutch jury consists of: Pim Peters of IMD consulting engineers, Albert Herder of Studioninedots, Arjen Ketting of MVRDV, Paul Stavert of Powerhouse Company and Jan de Koning of De Jong Beton. In previous editions, there were around 40 entries. “We are very curious about this edition’s entries,” Cindy Vissering concludes.

3D printing already in reach

On January 15, 2019, Weber Beamix opened Europe’s first commercial, industrial production site for 3D printing of concrete elements for construction in Eindhoven. Today, production is in full swing. Various components are being printed and fielded. There is even a second permanent production facility in Europe, a mobile factory for rental and a fixed product portfolio including custom-made slope stairs.

According to Pieter Bakker, 3D printing of concrete mortar makes individual serial production possible. This creates a huge increase in design freedom. Pieter: “The magic word is smarter construction, including parametric design. This is a process in which models or designs are automatically generated based on parameters, such as dimensions, material thickness or geometry. The print robot can vary endlessly based on different parameters. For example, you can give all the columns of a bridge or viaduct a different shape. Moreover, the printer only lays concrete where it is needed for structural strength. We therefore achieve savings of 30 to 40 percent. Formwork is also no longer needed, so there is also no waste.”

Furthermore, according to Pieter, the whole process is faster and the margin of error decreases. During the design process, everyone is looking at the same design. Changes are immediately calculated and applied digitally. “You press ‘Ctrl+P’ at the end, so to speak, and the printer immediately starts production. For the construction site, the most important thing is that less time is needed on site, so also less man hours. This means faster, but also safer work, and construction becomes more attractive to young people through automation and robotisation. Another advantage is that you need fewer people on the construction site, which is important in these times of scarcity of skilled workers.”


Pieter Bakker concludes, “I am convinced that 3D concrete printing is claiming its place in the market. The technology is no longer in its infancy, but we also really have plenty of challenges ahead of us.”

Modern Burj al-Hamam breaks record at the Floriade

This unique object has earned with this a well-deserved place in the Guinness World Records book. The ‘pigeon tower’ was designed by Dar & the Expo Pavilion group and printed by Saint-Gobain Weber Beamix in Eindhoven.

The Pigeon Tower

The 3D printed Burj al-Hamam pays tribute to the traditionally built pigeon towers in Qatar and is characterized by its special, architectural shape. During the migration season, the tower provides a shelter for more than a thousand pigeons. At the same time, it provides an ecological way of farming. Thanks to the clever construction, the pigeon droppings can be collected and used as fertilizer for local farms. Visitors to the Floriade can also get to know the 3D printed structure and construction inside and up close. Since many wild pigeons now gratefully use the tower, access is of course entirely at your own risk.

Groundbreaking design

The Burj al-Hamam was built without steel reinforcement or poured concrete. At 12.1 meters it is the highest 3D printed tower in the world. This is confirmed by a measurement by an official of Guinness World Records. To further reduce the carbon footprint, Saint-Gobain Weber Beamix has significantly reduced the energy requirement of the production process and the amount of material. As a result, up to 60% less CO2 was emitted for the towers than with the traditional way of building. In this way, the Weber Beamix concrete printing factory has pushed the boundaries of concrete printing even further.
