Samsung E&A will provide its 3D printing mortar, while CPAC will contribute engineering support and architectural services for projects in Saudi Arabia. SCG International will oversee the supply chain, ensuring the delivery of 350t of cement.

US: ICON says that it has nearly completed the construction of its 100-unit Wolf Ranch housing development in Georgetown, Texas. The company is 3D printing the development using its Vulcan printer. Reuters has reported that the company designed the buildings to be resistant to water, mould, termites and extreme weather.

Senior project manager Conner Jenkins said "3D printing brings a lot of efficiency to the trade market. So, where there were maybe five different crews coming in to build a wall system, we now have one crew and one robot.”

Kazakhstan: Denmark-based COBOD supplied its BOD2 3D printer for use in BM Partners’ construction of a house in Almaty. BM Partners designed the house, which has enhanced weather and earthquake resistance. It is fitted with expanded polystyrene concrete (EPC) insulating blocks.

Switzerland: Holcim has partnered with the Federal Institute of Technology (ETH) Zurich’s Block Research Group, incremental3D and Zaha Hadid Architects Computation and Design Group for the launch of Phoenix, a 3D-printed concrete bridge made using reduced-CO₂ circular technologies. The bridge employs Holcim’s ECOCycle recycled 3D-printing concrete and stands through compression, without reinforcement, reducing the volumes of materials used by 50% compared with conventional construction methods.

Holcim head of global research and development Edelio Bermejo said “I am thrilled to unveil Phoenix, a monument to sustainability and the result of a fruitful collaboration with our partners to meet a common goal: demonstrating that essential infrastructure can be designed and built in a way that is circular and low-carbon today. This project showcases the impact that innovation can have in Holcim’s mission to decarbonise building for a net-zero future.”

UAE: Dubai Municipality has launched the world's first system for certification and conformity marks in the field of 3D printing in the construction industry. The Municipality says that this will serve as a proactive measure to streamline procedures and improve the quality of concrete mixes used in factories licensed and operating in the Emirate and that it will play a ‘pivotal role’ to advance Dubai’s leading position for cutting-edge and sustainable construction technology.

Dawoud Al Hajri, Director General of Dubai Municipality, said “The certification and conformity mark system for factories and entities operating in the field of 3D printing for construction has been comprehensively established in alignment with Dubai Municipality’s proactive vision. This system embraces international best practices to provide exceptional services to both individuals and the community, thereby enhancing Dubai's global reputation and aligning with Dubai Municipality’s strategic objectives outlined in Dubai's 2030 Plan. Additionally, the system supports Dubai’s 3D printing strategy, launched by His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai. The strategy aims to utilise technology for the advancement of humanity and position the UAE and Dubai as prominent regional and global hubs for 3D printing technology.”

Alia Al Harmoodi, chief executive officer of the Environment, Health, and Safety Agency at Dubai Municipality, highlighted that the main focus of the new system includes assessing product and raw material quality, ensuring the efficiency of manufacturing equipment and machinery, defining technical standards of manufacturing operations at every stage of production, and ensuring efficiency of management systems within factories.

US: Geopolymer cement and concrete producer Renca has supplied its geopolymer 3D printing mortar for the construction of a house in the Western US. The product contains no cement, lime or gypsum due to the non-hydraulic binding properties of the mortar. It contains industrial by-products and has a faster setting time than mortar produced with ordinary Portland cement (OPC), as well as 90% lower CO₂ emissions.

Renca said that its geopolymer mortar performed well despite the desert setting of the project, with dramatic changes in temperature. It added, "Even though geopolymer mortars require a specific approach towards the mixing procedure and, unlike cementitious-based products, need to be mixed in a batch mixing system, this milestone opens new horizons. Renca's current research and development seeks to develop a one-component geopolymer mortar for continuous mixers, as well as a 2K system where you can control the setting time right at the nozzle."

US: Eco Material Technologies has supplied its PozzoCEM Vite clinker-free cement to 3D printing construction firm Hive 3D for its The Casitas @ The Halles project in Texas. PozzoCEM Vite cement has 92% lower CO₂ emissions than ordinary Portland cement (OPC). The producer said that concrete produced using PozzoCEM Vite is also more durable and longer lasting than OPC-based concrete. Eco Material Technologies and Hive 3D developed a custom batching system to mix PozzoCEM Vite cement and local Texan sand for use in the project. Eco Material Technologies said that the system created a significant cost reduction compared with other available printable mortar technologies.

Eco Material Technologies recently launched a new 99% reduced CO₂ PozzoCEM formulation, which it expects to use in future projects with Hive 3D. Other reduced-CO₂ cements produced by Eco Material Technologies include its PozzoSlag 50% ground granulated blast furnace slag cement. In total, Eco Material Technologies has supplied 1Mt of reduced-CO₂ cements across 4000 construction sites since 2012. It said that it expects to announce multiple new infrastructure projects and strategic partnerships later in 2023.

Eco Material Technologies' CEO Grant Quasha said “Hive 3D’s commitment to building the first 100% cement replacement 3D printed homes aligns with our goal of transitioning the construction industry away from using materials that generate approximately 8% of the world’s carbon emissions each year."
