3D Printed Elastomeric Foam Lattices for Energy Absorption and Mechanical Testing

A 2026 dataset from figshare by Abilash Rosario Arockiyasamy documents a design and fabrication strategy for 3D-printed elastomeric foam lattices. The dataset includes experimental and simulation results for hierarchical grid-stiffened structures, such as a star-diamond interwoven lattice, achieving a 1.7-fold expansion and a density of 215 kg/m³. The described lattices demonstrated a 600% increase in stiffness and a 1100% increase in strength compared to non-foamed conditions.

Use Cases

• Optimizing lattice topology for energy absorption based on the described hierarchical grid-stiffening design.
• Simulating mechanical performance of 3D-printed elastomeric foams based on the experimental validation data.
• Developing cushioning materials for shoe soles based on the prototype application mentioned in the description.
• Comparing the energy absorption efficiency of different lattice geometries, such as the star-diamond interwoven lattice versus the Kelvin lattice.

Strengths

• Includes specific performance metrics, such as a 1.7-fold expansion, a density of 215 kg/m³, and a 48% energy absorption efficiency.
• Describes a validated fabrication method combining vat photopolymerization and thermal foaming for complex structures.
• Provides comparative results against a baseline (Kelvin lattice), showing a 240% higher energy absorption with foam integration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset's primary files are DOCX and JPG formats, which may require specific tools for data extraction and analysis.
