A new scientific publication from the TRANSITION project has been published in the Journal of Manufacturing and Materials Processing. The article, “High-Volume Cement Replacement with Oil Shale Ash and Metakaolin in Pre-Blended Compositions for 3D Printing,” presents the development of a low-carbon cementitious material for 3D concrete printing, in which 40% of Portland cement is…

🐝 We are pleased to see another collaborative project move from concept to reality.The newly installed insect houses in Riga’s urban meadows demonstrate how digital fabrication and low-emission construction materials can contribute to more biodiversity-friendly cities. Developed together with Collective Fabula, the project explores how 3D printing technologies can be used not only for human-centred…

RTU Institute of Architecture and Design hosted the Erasmus+ Blended Intensive Programme workshop “Bio-Based Fibre Architecture”, organised in collaboration with the Royal Danish Academy, Aalto University and Kaunas University of Technology. During the week, students worked in interdisciplinary teams, combining digital modelling, experimental design methods and hands-on material work. The workshop was organised around three…

♻️ As part of the Transition project we recently hosted a group of talented young interns for a deep dive into the world of #3Dprinting. By blending youthful curiosity with our team's expertise, we are exploring how #AdditiveManufacturing can revolutionize #sustainable building practices.💪 Empowering the next generation of engineers is key to a greener, smarter…

10 December is also the “LabLab birthday”, marking the day when the very first LabLab was unveiled at RTU Science and Innovation Centre, so it was the perfect moment to present the next chapter in the LabLab story. LabLab is the mascot of RTU Science and Innovation Centre, and this new sculpture is much more…

IExciting times are ahead at our lab! The installation of the large-scale prototype LabLAB 2.0 has officially begun, marking a major milestone for our research and development efforts. This landmark prototype has been designed in collaboration with students—through their competition contributions—and built using the very mixtures developed within our project framework, with a substantial amount…

🎉 Congratulations to the winners of our student 3D Concrete Printing Design Competition — you truly earned it!After several months of design work, expert consultations, and intense competition, we are proud to announce the top entries that will shape the next large-scale 3D printed sculpture at Riga Technical University. The winning team — RTU students…

On February 27th, we had the honor of hosting the Latvian Concrete Association’s members’ meeting at RTU, where we showcased cutting-edge advancements in 3D concrete printing with low-carbon materials. Our workshop highlighted innovative uses of oil shale ash in concrete and 3D-printable mixtures, demonstrated state-of-the-art printing technologies in our lab, and presented key testing methods…

📅 September 10-12, 2025 | 📍 Riga, Latvia The IMST 2025 Conference will bring together researchers, industry professionals, and experts to discuss the latest advancements in materials science, structural engineering, and construction technologies. Building on the success of previous editions, IMST continues to provide a platform for high-quality scientific exchange, fostering collaboration and innovation in…

I invite everyone to a great guest lecture that will take place as part of our 3D concrete competition already tomorrow. Roberto Naboni, head of SDU CREATE, will give a lecture on Design-Driven Solutions for Low-Carbon 3D Concrete Printing, it will be a great opportunity to learn about the 3D printing process from an architect's…
