Abstract
In recent years, 3D printing has become increasingly popular for producing biodegradable products and for exploring a variety of applications. The development of polyhydroxy-co-3-butyrate-co-3-valerate (PHBV) and Polybutylene adipate-co-terephthalate (PBAT) blend for 3D printing has been the subject of extensive research. This paper examines the impact of printing parameters on the mechanical properties of 3D-printed components. The study successfully optimized the mechanical properties of 3D-printed PHBV/PBAT blend parts, achieving a tensile strength of 22.96 MPa, a modulus of 767 MPa, and an elongation percentage of 180 %. These results were obtained by identifying the optimal printing parameters through a Taguchi L9 design and Desirability Function Analysis (DFA), specifically a 0.35 mm layer height, 210 degrees C nozzle temperature, and 100 % infill density. The addition of PBAT significantly enhanced the ductility of PHBV, marking a substantial improvement in elongation. This research provides a robust framework for optimizing the performance of biodegradable blends in additive manufacturing, with promising implications for future applications in sustainable material development.

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
