MICROSILICA IN 3D CONCRETE PRINTING TECHNOLOGY ➡ Microsilica can be used in 3D concrete printing technology to improve the mechanical, strength and processability properties of printed concrete structures. But not only… Recently, the Zachodniopomorski Uniwersytet Technologiczny w Szczecinie printed a medium-scale demonstration model to test the performance of the printing system for mixtures containing recycled fine aggregates. For this purpose they used, among others: our concentrated gray microsilica (information about which you can find in our previous posts). In the Recycl3D ERAMIN project, they are looking for sustainable solutions to find end-uses for recycled fine aggregates and fines. The high content of binder and fine aggregate can significantly reduce the consumption of natural aggregates and reduce the amount of cement, which reduces the carbon footprint of 3D concrete by up to 10%.

By improving the microscopic structure of concrete, silica fume can reduce microcracks that may occur during the curing process. Its addition increases the adhesion between concrete layers in 3D printing, which leads to more uniform and stable structures. This, in turn, can increase the overall print quality and durability of the printed items. The microscopic properties of microsilica can help maintain accurate dimensions and detail in printed elements, making prints more precise.

3D printing with concrete has become increasingly popular, using a cement-like substance instead of plastic filament to build structures layer by layer. This approach accelerates construction, aligns with architectural designs, lowers labor costs, and reduces waste. Nonetheless, the range of materials available is limited, raising concerns about sustainability and durability. Researchers at the University of Virginia have incorporated cellulose nanofibrils (CNF), sourced from tree pulp, into 3D-printed concrete to improve its eco-friendliness and strength. Developing the optimal mixture proved difficult, as it needed to flow well during printing while also hardening into a stable form. CNF, which consists of ultra-fine fibers from plant cellulose, effectively enhanced both the flow and strength of the material. The team discovered that incorporating at least 0.3% CNF significantly improved the concrete's properties, resulting in better bonding and structural integrity.

#Published I am very excited to share that our most recent publication: “Workflow for generating, simulating, and optimizing form and toolpath in 3D concrete printing of vaults” was published in Automation in Construction Elsevier. This paper is the culmination of my dissertation and proposes a design workflow that includes form and toolpath generation, structural simulation, and gradient-free constrained optimization tailored for 3DCP scaffold-free enclosures and extendable to other structural forms. This paper explores the potential of additive construction to automate the fabrication of enclosures, the impact of scale and fabrication strategy, and compares the performance of different types of vaults. Finally, it is used to fabricate a cross-vault structure. I want to thank the co-authors Dr. Jose Pinto Duarte, and Dr. Nathan Brown for their extremely valuable insights. This research was financially sponsored by Penn State University, Fundação para a Ciência e a Tecnologia (FCT), X-Hab 3D, Gulf Concrete Technology (GCT), HiltiFoundation, and Xtreme Habitats Institute.

Scientists have cracked the code for more rigid concrete using nature-inspired designs and 3D printing #technology. 🔬 Researchers at Princeton University have developed a new method to create stronger, more crack-resistant #concrete by mimicking structures found in fish scales and mantis shrimp. Using large-scale robotic 3D #printing, they fabricated concrete beams with intricate internal architectures that significantly improved fracture toughness compared to conventional concrete. The key innovation was arranging the concrete in "bouligand" and "double-bouligand" patterns - helical structures that cause cracks to twist and deflect rather than propagate straight through. This bio-inspired design increased the concrete's fracture toughness by up to 88% compared to regular cast concrete. While 3D-printed concrete is often weaker due to weak interfaces between printed layers, this study deliberately exploited those interfaces to enable beneficial crack deflection mechanisms. The researchers suggest this approach could lead to more durable concrete structures with longer lifespans and improved safety. This breakthrough demonstrates how advanced #manufacturing and bio-inspired design can revolutionize traditional construction materials and opens new possibilities for more robust and resilient concrete to cracking and damage. TL;DR #1 - Scientists used 3D printing to create tougher concrete inspired by fish scales and mantis shrimp structures. #2 - The "bouligand" and "double-bouligand" patterns increased concrete's fracture toughness by up to 88%. #3 - This method exploits weak interfaces in 3D-printed concrete to create beneficial crack deflection. #4 - The bio-inspired design causes cracks to twist and deflect rather than propagate straight through. #5 - This approach could lead to more durable, longer-lasting concrete structures with improved safety. #3DPrinting #Construction #MaterialsScience #Engineering #Innovation

#3DPC #PolyU We are glad to announce that our research paper "Intelligent real-time quality control for 3D-printed concrete with near-nozzle secondary mixing" has been published in Automation in Construction with an Impact Factor of 10.3 under the supervision of Prof. Shipeng Zhang and Prof. Chi-Sun Poon. Real-time quality control is considered one of the grand challenges in the additive construction of concrete structures. Our research proposed an intelligent monitoring method coupled with a feedback adjustment system to accomplish real-time printing parameter adjustment during manufacturing process of 3DPC. The proposed automatic printing regulation prototype showed great potential to be applied in larger printing projects. Highlights: ★ Material status of 3DPC is adjusted in real time by inline secondary mixing with accelerator. ★ Geometry and material status of 3DPC is obtained by image classification based on AI-aided computer vision techniques. ★ Modified lightweight Inception-ResNet shows high accuracy and generalization compared to VGG Network. ★ Quality of printed filament is dynamically adjusted by automatic feedback prototype to achieve proposed material status and geometric characteristic.
