Abstract
Laser consolidation (LC) is a novel computer-aided manufacturing process being developed by the Industrial Materials Institute of National Research Council of Canada (NRC-IMI). This rapid manufacturing process produces net-shape functional metallic parts layer-by-layer directly from a computer-aided design (CAD) model by using a laser beam to melt the injected powder and resolidifying it on the substrate or previous layer. As an alternative to the conventional machining process, this novel manufacturing process builds net-shape functional parts or features on an existing part by adding instead of removing materials. In this paper, laser consolidation of various high performance materials (such as Ni-alloys, tool steels, etc.) will be demonstrated to manufacture functional components or test-pieces (such as shell-based mold inserts, impeller, intersected multihexagon tube, goblet shape, etc.) for potential aerospace, automotive, and other applications. In the paper, dimensional accuracy of various laser-consolidated test-pieces will be measured and compared with CAD models. In addition, an example will be given on laser consolidation to build complex cold spray nozzles that are difficult to make otherwise and significantly improve the performance.

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
