Mechanical Characterization of Ultra-Violet-Curable Resin-Based Polymer Foams Containing Triply Periodic Minimal Surface Lattice Structures
Bibliographic record
Abstract
Triply periodic minimal surface lattice structures are three-dimensional arrays of complex cells that can only be efficiently manufactured by 3D printing. The mechanical properties of these lattice structures depend on lattice parameters such as cell sizes along the X, Y, and Z axes, and wall thickness. Designing such lattice structures for soft polymers permits the manufacturing of polymer foams with controllable mechanical stiffnesses. The objective of this work is to design and 3D print polymeric foams made of lattice structures and evaluate the effect of lattice parameters on the resulting stiffness. Lattice parameters define the lattice geometry and stiffness. Ten specimens with different lattice parameters were designed and 3D printed using a low-cost desktop liquid crystal display 3D printer using ultra-violet-curable resin. Then, following ASTM D3574-17, these samples were subjected to compression tests. An experimental analysis was conducted to examine the deformation characteristics of these structures, focusing on parameters such as yield strain, initial stiffness, and the maximum force at 50% compression.

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.
