You are what you breathe: observing airborne carbon fiber particulates during FFF printing of PA6-CF filament
Bibliographic record
Abstract
Carbon fiber reinforced filaments are increasingly popular in Additive Manufacturing (AM) due to their enhanced mechanical properties compared to traditional materials like PETG, ABS, and Nylon. However, these materials present challenges, including proper drying requirements and potential fiber transfer to the skin during handling. In this study, microscopic examination of fingertips after handling PA6-CF parts revealed significant fiber transfer, raising concerns about airborne fiber dispersal during printing. This research aims to observe the dispersion of fibers from PA6-CF filament using a Bambu Lab X1C desktop Fused Filament Fabrication (FFF) system. A custom apparatus with filter was developed to capture dispersed fibers during printing experiments. The used filters were then observed for fiber content to draw conclusions. Safety precautions are recommended along with a proposed alternative slicing method to minimize fiber transfer from final parts. This study contributes to a safer working environment for 3D printing enthusiasts and professionals by addressing potential health risks associated with airborne fiber dispersion.

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.
