The success of 3D concrete printing technology depends on the perfect balance of the rheological properties of the material used. Confabric subjects the mix designs developed for each new project or specialized application to rigorous testing processes. These tests ensure the concrete flows smoothly through the nozzle while guaranteeing that overlapping layers rapidly gain strength without collapsing under their own weight.

• Printability Tests: Fluidity control of the mixture during pumping and extrusion.
• Buildability Analysis: Static resistance displayed by fresh concrete as it rises in layers.
• Open Time Measurement: Optimization of the period the mixture remains workable relative to printing speed.
• Interlayer Adhesion: Measuring the bond strength between layers for structural integrity.
• Setting Time and Early Strength: Rapid curing and structural stability assessments.

• Project-specific optimized material costs and high performance
• Dynamic mix recipes adaptable to different climatic and site conditions
• Structural safety pre-validated with laboratory data
• Integration of sustainable and low-carbon alternative binders into the system
