Identification of constitutive theory parameters using a tensile machine for deposited filaments of microcrystalline ink by the direct-write method
Bibliographic record
Abstract
ABSTRACT: A custom-designed tensile machine is developped to characterize the 10 mechanical properties of ink micro-filaments deposited by Direct-Write method. The 11 Direct-Write method has been used for the fabrication of a wide variety of micro12 systems such as microvascular networks, chaotic mixers and laboratory on-chips. The 13 tensile machine was used to measure the induced force in ink filaments during tensile 14 and tension-relaxation tests as a function of the applied strain rate, the ink composition 15 and the filament diameter. Experimental data was fitted by a linearly viscoelastic 16 model using a data reduction procedure in order to identify the constitutive theory 17 parameters of the deposited ink filaments. The model predictions based on the defined 18 constitutive theory parameters were closed to the experimental data generated in this 19 study. Such models will be useful in the development and optimization of future 3D 20 complex structures made by direct-write method.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
