Abstract
View Video Presentation: https://doi.org/10.2514/6.2023-1714.vid Fiber reinforced additive manufacturing (FRAM) is an emerging technology which combines the benefits of additive manufacturing and composite materials. Current research surrounding FRAM focuses on the manufacturing process and neglects opportunities to leverage design freedom provided by FRAM in design optimization. This work proposes a novel design optimization method which optimizes global print orientation and topology of a component to improve a structural objective function. The method considers two classes of design variables: (1) print orientation design variables and (2) density-based topology design variables. Print orientation design variables influence anisotropic material properties of the FRAM material considering complex loading and are used as a basis for topology optimization. The methodology is applied to an industry-level case study. Considering weighted structural compliance as an objective, component performance is improved by 13.3% compared to alternative FRAM optimization solutions and improved by 36.6% compared to a metallic baseline design by applying the proposed method.

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
