Abstract
This study enhances the efficiency of concrete 3D printing for prefabricated lightweight slabs by implementing lean principles and robotic automation. Benchmarking an existing optimized slab design and simulating a lean robotic cell revealed significant improvements in production time, automation efficiency, quality assurance, cost savings, workspace optimization, and continuous improvement through sensor data collection. The study compares the current manufacturing process with a proposed lean process for a complex octagonal slab design. Assumptions on building dimensions, slab requirements, printing methods, and materials facilitated the analysis. The current process takes 10 hours per slab, including printing, reinforcement placement, and drying. Lean principles aim to reduce waste and boost productivity, enhancing the manufacturing efficiency of prefabricated lightweight slabs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
