Abstract
This investigation presents, to the authors’ best knowledge, the first 3D printed continuous fiber-reinforced polymer composite deployable booms. The precise material placement capabilities of the fused filament fabrication (FFF) process are leveraged to produce cylindrical bistable slit tube booms with lattice architectures. The influences of fiber angles, lattice density, and initial shell curvature on the existence and form of stable coiled configurations as well as flexural rigidity properties are investigated. A computational procedure for automatically generating finite element models directly from material deposition paths is presented, with predicted shell behaviors showing strong agreement with experimental results using both homogenization and full-scale modeling approaches. Lattice shell architectures are revealed to exhibit higher flexural rigidity properties than continuum architectures on an equal-mass basis. Finally, bistable slit tube booms that can coil into unique stable configurations via the tailoring of material deposition paths are demonstrated.

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
