Abstract
3D printers that precisely fuse plastic filament are enabling the medical device manufacturing sector to produce high-quality plastic medical devices and implants. However, the low-temperature fusing process implies that post-production sterilization must also occur at a low temperature or destroy the precision of the product. This study characterizes the effects of hydrogen peroxide (H 2 O 2 ) vapour sterilization on ASTM-compliant 3D printed tensile samples of polylactic acid (PLA), polycaprolactone (PCL), and polycarbonate (PC). The sterilization process caused physical deformations in PCL. Additionally, increases were observed in PCL and PC sample thickness, and in PC sample width. Decreases in Young’s Modulus (E) were found in all three materials, while UTS decreased in PC, and strain at UTS increased in PCL. The findings demonstrate that the 3D printed materials can be compatible with H 2 O 2 vapour sterilization, but products must be designed to accommodate for changes that occur due to sterilization.

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
