Biomedical Stent Model for 3D Printing and CAD ApplicationsOverview

This is a highly detailed, parametric 3D model of a stent-like structure designed in SolidWorks, ideal for biomedical engineering, 3D printing, and finite element analysis (FEA). The model features a cylindrical lattice with a precise zigzag pattern, optimized for both visualization and functional prototyping. Perfect for researchers, engineers, and hobbyists working on medical device development or educational projects.

• High Accuracy: Modeled with precise tolerances (±0.01 mm) and validated using SolidWorks’ Check Entity tool for clean geometry.

Applications

• Biomedical Research: Ideal for prototyping stent designs or studying mechanical behavior (e.g., radial strength, foreshortening).

• 3D Printing: Perfect for creating physical prototypes for testing or educational displays.

• Engineering Education: Suitable for teaching CAD, FEA, or medical device design.

• Custom Projects: Configurable for specific diameters or lengths, adaptable for other tubular lattice structures.

Usage Notes

• 3D Printing: Recommended layer height of 0.1–0.2 mm for SLA or 0.2–0.3 mm for FDM. Use supports for complex lattice sections.

• CAD Compatibility: STEP/IGES files ensure compatibility with other CAD software (e.g., AutoCAD, Fusion 360).

• Licensing: Royalty-free for commercial and non-commercial use (see 3DExport license terms).

• Customization: Contact for bespoke modifications (e.g., adjusting zigzag angle ~33.3° or pattern density).
