3d concrete printing

High-performance super-mobile concrete batch plant for 3D printers.
SOLUTIONS

Revolutionary batch plant solutions for 3D concrete printing

3D concrete printing companies often struggle with concrete quality issues. The batch slump varies, and printers are prone to breaks. Instead of concrete, printing companies are forced to use mortar, which is more expensive and has a very high cement content. Ultimately, this results in higher carbon emissions.

With our 3D-Mix concrete batch plant, you can effortlessly print houses with concrete.

By incorporating a bigger aggregate size of up to 1/2” (12 mm), you achieve enhanced volumetric stability of the concrete. This, in turn, enables increased printhead speed and makes it possible to construct multi-floor houses. 

Our 3D-Mix concrete batch plant:

  • Can mix concrete instead of mortar
  • Reduces out-of-spec concrete
  • Ensures fewer printer breaks
  • Saves cement and reduces carbon emissions

Frequently asked questions about 3D concrete printing

FAQs

These are questions we’re often asked. We hope you find these helpful. If you still have a question we haven’t addressed, please contact us directly.
What are the common challenges faced by concrete plants when it comes to 3D printing?

When producing 3D-printed concrete – not mortar – it is necessary to achieve sufficient pumpability and buildability characteristics. In 3D printing, these go far beyond the usual standards for conventional concrete.

The plants must work with high cement content and aggregates of up to 1/2” (12 mm). They also must use multiple admixtures with automatic dosing and accurate (not volumetric) scales. Plus, integration of the accelerator at the nozzle head enables rapid setting of the mix.

The process of producing 3D-printed concrete mandates an exceptional level of precision in the dosing and weighing of all materials. Simultaneously, it involves accurate moisture management and temperature control. A small mistake in slump quality can ruin the batch, block the printer or compromise the structural integrity.

A common mistake occurs when concrete producers attempt to use a standard batch plant for 3D-printed concrete production. Such plants are unable to meet the required tolerances, leading to operational challenges.
HOW DO TECWILL 3D-MIX PLANTS DIFFER FROM TRADITIONAL BATCHING PLANTS?

We have developed a completely new “flying” aggregate weighing system equipped with improved OptiMoist aggregate moisture measuring technology that ensures accurate dosing of raw materials.

Normally, mortar is used to print houses. It is a very expensive cement-sand mix. At the same time, it is brittle and lacks sufficient tensile capacity. Because of the high cement content, the price of such a house is unnecessarily expensive.

With our technology, you can use concrete for 3D-printed houses. Concrete has higher aggregate content and less cement. The price of such a house is lower, and less carbon is emitted during production.

With Tecwill’s 3D-Mix plant, you can produce all types of concrete mix designs needed for the project, including:

  • Concrete for 3D printing
  • Ready-mix concrete
  • Roller-compacted concrete
  • Precast concrete
WHAT BENEFITS DOES THE USE OF CONCRETE PROVIDE FOR 3D-PRINTED HOUSES?
  • Bigger aggregate size of up to 1/2” (12 mm) can be used
  • Lower cement content and smaller carbon footprint
  • Improved volumetric stability of concrete due to coarse aggregate
  • Decreased hydration heat and shrinkage due to coarse aggregate
  • Greater stability and strength of the printed structures
  • Stronger multi-floor printed houses
