  • 3D printing of building structures
    Printing at speeds up to 100 cm/sec
  • Printing towers and foundations of wind turbines
    Accelerate the clean energy transition with concrete 3D printing
  • Robotic Continuous Fiber 3D Printing
    Modular smart factories, advanced carbon and fiberglass composites
3D printing
3D printing is an innovative technology that uses material placement software to create a 3D object or structure without the need for standard formwork. The most common paving process is based on the extrusion of cement-based composites, be it fine-aggregate mortar or coarse-aggregate concrete. 3D printing makes it possible to produce products of complex geometry on a fully automated plant. Printing is possible with a robotic arm, which is more suitable for "experienced" operators (usually robot suppliers themselves) to print individual elements with high complexity and detail, and a portal 3D printer - ideal for printing much larger structures, for example, entire buildings.

Key advantages of the technology:
  • how to save materials,
  • increasing the efficiency of production of complex concrete products,
  • new architectural ideas and design strategies.
3D construction process
Construction speed depends on many factors: building size, material properties, worker experience, and other project management factors. Small buildings less than 50 m2 can be built in one day. It is possible to build high-rise structures and multi-storey buildings.

It usually takes 4 hours to set up a 3D printer. Curing time is highly dependent on weather conditions and the composition of your mix and can take anywhere from 1 to 20 minutes or more. At the same time, as a rule, there are no strict requirements for the use of materials for the building mix - it can vary greatly depending on local conditions.

The construction process using a 3D printer can vary, but for example, when building a standard building, it will consist of:
  • Site preparation
  • Printer settings
  • Foundation Outline Prints
  • Wall prints on the first floor
  • Decks settings
  • Repeat procedure for multi-storey buildings
  • House closings (roof, windows, doors)
  • Finishes (paint, floors, electricity, HVAC).
