Investigation of laser consolidation for manufacturing functional net-shape components for potential rocket engine applications
Bibliographic record
Abstract
Laser consolidation is an emerging novel computer-aided manufacturing process that produces net-shape functional metallic parts layer by layer directly from a CAD model by using a laser beam to melt the injected powder and re-solidifying 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 material. In this paper, laser consolidation of IN-625 and Ti-6Al-4V alloys has been investigated to build several generic shapes representing parts that may have potential rocket engine applications. Laser consolidation produces components with good surface finish, dimensional accuracy and mechanical properties, and demonstrates the potential for direct manufacturing of functional net-shape components and tooling. In addition, some preliminary results demonstrate that the laser consolidation, in combination with solid-state, net-shape powder metallurgy processing, may provide a unique manufacturing capability to make very complex components for the rocket engines.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
