Quantifying water-driven geometric uncertainties in powder bed concrete printing using high-resolution 3D modeling

Annika Robens-Radermacher, Christoph Wolf, Daniel Kadoke, J\"org F. Unger, Petr Hlav\'a\v{c}ek

Varying water dosage in powder bed concrete 3D printing creates systematic geometric deviations that designers can offset by pre-adjusting the digital model.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments show that small changes in water content can cause large, systematic deviations, including edge rounding and swelling. ... we demonstrate a design-compensation concept that pre-adjusts digital geometry to counter predictable deviations, improving accuracy without post-processing.

C2weakest assumption

This is explained by excess voxel water diffusing into surrounding powder, leaving the effective water-cement ratio largely unchanged. (This premise supports the claim that mechanical properties remain stable despite varying water dosage.)

C3one line summary

Experiments show small changes in voxel water dosage cause large, directionally biased geometric deviations like edge rounding and swelling in printed concrete, which can be reduced by pre-adjusting the digital CAD model.
