Abstract
Polydimethylsiloxane (PDMS) is widely used to build biomedical microdevices because of its excellent properties. Prototyping 2D and 3D PDMS microdevices normally requires a long curing time and must go through multiple steps. In this paper, we propose femtosecond laser stereolithography for the rapid prototyping of PDMS 2D and 3D microstructures. This work presents a new way of rapid curing of PDMS resin on a microsecond timescale using femtosecond laser pulses of megahertz pulse frequency. The proposed technique permits single-step curing and is capable of fabricating 2D and 3D structures in micro-scale. The rapid localized curing can be explained by the volume-constrained quick temperature rise due to the accumulated heating at repetitive irradiation. The rapid cooling following the curing limits the decomposition and, therefore, the PDMS retains its mechanical strength.

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
