Safety-Oriented Optimization of Polymer Components in FDM Using MCDM
Bibliographic record
Abstract
Fused deposition modeling (FDM) has become a widely adopted additive manufacturing method for producing functional polymer components across industrial and biomedical domains. However, ensuring both mechanical performance and safety reliability remains challenging due to the sensitivity of FDM outcomes to process parameters. This study proposes a decision-making framework integrating Fuzzy Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to optimize FDM process parameters—layer thickness, infill density, print speed, and extrusion temperature—based on mechanical and safety performance indicators. Experimental and decision analyses identified an optimal configuration of 0.2 mm layer thickness, 80% infill density, 60 mm/s print speed, and 220 °C extrusion temperature, resulting in a 17.6% improvement in tensile strength and a 14.3% increase in safety factor, calculated as the ratio of maximum tensile stress to yield stress, compared to baseline settings. The proposed framework provides a systematic pathway for balancing mechanical integrity and safety reliability in polymer additive manufacturing, offering practical value for industrial optimization and sustainable design.

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.
