Features & Benefits

In this new world, your well-trained team of 4-8 people can go from packed to printing in 1 to 1.5 days (depending on printer size), without the use of a crane. This is made possible by the aluminium structure and plug-and-play electronic systems.

Once assembled, make use of your handheld tablet to move within and around the printer while maintaining complete control.

The IROKO’s ™  advanced data monitoring and recording systems can be used to produce accurate records of environmental and print parameters throughout the printing process. These can be extremely useful to the operators as well as the engineers when it comes to signing off the printed structures.

Some of the benefits that you can expect to experience while using this new technology when using your IROKO™ 3D Concrete Printer are:

  • Servo drive Motors providing Speed and Efficiency: With the ability to rapidly fabricate complex structures in concrete with 3D printing significantly reduces construction time compared to traditional methods.
  • Cost-effectiveness: By minimizing labour and material waste, 3D concrete printing optimizes cost-efficiency. It eliminates the need for formwork and reduces the required manpower, resulting in significant cost savings for construction projects.
  • Purpose built operational software, HMI and SCADA for full Design Freedom and Print Customization: 3D Concrete printing enables architects and designers to unleash their creativity and push past the boundaries of traditional construction. It allows for intricate, customized designs that were previously challenging or impossible to achieve, opening a world of new possibilities.
  • Sustainability: This innovative technology promotes sustainable construction practices. By precisely depositing the required amount of material, 3D concrete printing minimizes waste and reduces the environmental impact associated with conventional construction methods. Additionally, it offers the potential to utilize eco-friendly and recycled materials, further enhancing sustainability.
  • Structural Strength and Durability: 3D Concrete printing produces structures with excellent strength and durability. The precision layering of materials and optimized geometries enhance structural integrity, resulting in robust and long-lasting buildings and infrastructure.
  • Versatility and Adaptability: Whether it is creating complex architectural features, prefabricated elements, or even entire houses, 3D concrete printing is highly versatile. It can be applied to various construction scenarios and adapt to different project requirements, offering flexibility and scalability.
  • Enhanced Safety: By reducing the need for manual labour and onsite construction activities, 3D concrete printing improves safety conditions for workers. It minimizes potential risks associated with traditional construction methods, such as accidents and injuries.
  • Waste Reduction: Traditional construction often generates significant waste, including excess materials and unused formwork. 3D Concrete printing minimizes waste by utilizing only the required amount of material, optimizing resource usage, and contributing to a more sustainable construction industry.

These benefits collectively demonstrate how 3D concrete printing is transforming the construction landscape, providing faster, cost-effective, sustainable, and highly customizable solutions.
