Abstract
Abstract In this study, microfluidic extrusion of structurally anisotropic hydrogel sheets formed by cellulose nanocrystal methacrylate (CNC‐MA) and gelatin methacryloyl (Gel‐MA) is reported. The precursor CNC‐MA/Gel‐MA ink has temperature‐responsive and shear‐thinning properties, which make it compatible with extrusion‐based printing. To preserve shear‐induced CNC‐MA alignment, the extruded hydrogels are cooled down and photocrosslinked. It is shown that by varying the cooling temperature, the degree of structural anisotropy of the CNC‐MA/Gel‐MA hydrogels can be controlled, which is further augmented by varying the volumetric flow rate during extrusion. The structural anisotropy of the hydrogels is preserved at physiological temperatures (37 °C) for 7 days. The hydrogel sheets exhibit anisotropic mechanical and swelling properties with enhanced mechanical strength and reduced swelling along the extrusion direction. The design and use of this hydrogel expands the ability to create structurally anisotropic hydrogels with applications in biological and biomedical research, soft robotics and fundamental studies of anisotropy‐induced properties.

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
