Why do #RoboticArms typically print with #mortar? If you’ve been following the #3DConstructionPrinting industry, you may have noticed that robotic arms primarily print with mortar. But why? ? Robotic arms are well-suited for intricate detailing, making them ideal for smaller projects that require precision and complex geometries. However, their lightweight components influence the materials they can support, including hose sizes. Most robotic arms use DN25 or DN30 hoses, which work best with fine-aggregate mortars. Because of this, mortar is the standard material for robotic arm printing. ? The advantage? Exceptionally smooth finishes that are perfect for detailed elements and intricate structures. ? One company that demonstrates this beautifully is Vertico from the Netherlands. Their impressive structures highlight the potential of robotic arm printing - see for yourself below!

Did you know? #RoboticArms play a large role in #prefabricated construction, but are only used in 25% of on-site 3D printing projects. A 2024 study stated that 13 of 14 prefabricated projects were completed with a version of a robotic arm. In contrast, only 16 out of 63 on-site 3D printing projects, used robotic arms. This raises an important question: Why are robotic arms more commonly used in prefabricated construction than on on-site construction? With six-axis movement, robotic arms offer flexibility and precision, making them well-suited for intricate designs, architectural facades, sculptures, and precast elements. While they can be used for larger on-site projects, their printable area and relocation requirements are important factors to consider when planning projects. What are your experiences with robotic arms in 3D construction? Let us know in the comments.

What are the two most common #3DConstructionPrinting technologies? Definitely the #GantrySystems and the #RoboticArms. But how do these two key #technologies compare? ? Gantry Systems: The choice for large-scale, high-volume construction ? ? Supports large-scale construction, from multi-story homes to infrastructure, and larger projects, as the print area expands with the printer size. ? The solid frame build for stability and accuracy makes it ideal for on-site, in-situ printing as well as pre-cast production where repeatability is key.? ? The 3D printer structure supports large material hoses and bigger aggregates, as required for real #concrete printing. ?? Requires setup time and repositioning when structures exceed the 3D printer's printable area. ? Robotic Arms: Best suited for smaller and more intricate objects ? Ideal for precision work, such as smaller objects, architectural facades, and sculptures, as it usually prints with #mortar containing smaller aggregates and higher cement con resulting in a smooth finish.? ? Well-suited for precast printing, allowing multiple smaller, more detailed objects to be produced in sequence at the same location, whereas gantry systems are typically used for larger precast objects. ? Compact and faster to position, making it more flexible for smaller-scale production. ?? Limited print area, making it impractical for large-scale buildings as it needs multiple relocation and re-setups.? ?? Primarily prints with mortar, as it often lacks the structural capacity for large hoses and real concrete printing. ? ?? Each technology has its strengths. Which one is the right fit for your projects and why? Let us know in the comments.

3 ?????? ?????????????????? ???? ?????? ???????????????? ???????????? ???????????????? ?????? ?????????? 3?? ???????????????????????? ???????????????? ???????????????????? Selecting the right #3DConstructionPrinting technology isn’t a one-size-fits-all decision. To find the best fit, start by considering these three key factors: 1?? Are you #3Dprinting entire structures or detailed objects? The size and complexity of your project determine which #technology is best suited, as some systems are optimized for large construction, while others are best at producing intricate objects and smaller elements. 2?? Will you be printing on-site or using a pre-cast approach? Pre-cast printing offers controlled conditions and repeatability, making it ideal for modular construction. In-situ printing enables full-scale structures to be built directly on-site, reducing transportation and assembly. Some technologies offer the flexibility to support both methods. 3?? What #materials do you want to use? Material selection impacts both structural integrity and the range of possible applications. Some technologies are designed for mortar, while others support real concrete with larger aggregates -directly influencing the strength, durability, and long-term performance of the final structure. ?? What factors matter most to you when choosing a 3D construction printing technology?

All 3D construction printing #technologies share one goal: automating #construction. But they don’t all achieve it the same way. ? While all 3D construction printing (#3DCP) technologies aim to improve productivity and efficiency, they differ in their strengths, whether in scalability, flexibility, design freedom, or material usage. ?

What does it take to achieve a successful #3Dprinted project? ? Achieving a successful 3D construction print involves more than just the material delivery process and equipment setup. A key aspect is #material consistency. Factors like temperature, humidity, and the composition of locally-sourced materials and additives impact material flow and print quality, influencing the final surface finish and structural integrity of the structures. Monitoring throughout the process helps maintain consistently high-quality prints. ? 3D printing teams have to develop the skills to interpret data and develop material mixes to maintain a high print quality throughout the 3D printing phase. To fully leverage the potential of #3DConstructionPrinting, building these skills is as essential as having the right equipment setup. ? At COBOD, we support our customers by providing specialized #training, equipping teams with the necessary skills at every step of the printing process.?The combination of advanced 3D construction technology,?material knowledge, and skilled operators helps automate physically demanding construction tasks, delivering faster, more cost-effective, and consistently high-quality results. ?

Let’s talk about the #material delivery process! A key aspect of #3DConstructionPrinting is how material is handled from storage to mixing, pumping, and extrusion. The right setup and automated connection between the 3D printer and Material Delivery System ensure consistent print quality and optimized #efficiency. There are different ways to manage material handling in 3D construction printing. One tested approach is the #Concrete Batching System, where dry materials are stored in a silo and dispensed into a mini batch plant. There, the #3Dprintable concrete mix is prepared using a material recipe tailored to specific project and environmental conditions. Once mixed, the material is pumped to the printhead’s hopper and extruded layer by layer with millimeter precision. Other systems may use different mechanisms depending on project needs, material types, and scale. By automating material flow, 3D construction printing enables faster, more consistent, and scalable building methods while reducing material waste and optimizing resources, making construction more #efficient and #sustainable. ??
