Paragraph starter

The selection of fabrication techniques significantly impacts the efficacy of engineered scaffolds for soft-tissue regeneration. Advanced methods such as electrospinning and 3D printing offer superior control over scaffold architecture, including pore size, interconnectivity, and surface topography, which are critical for cell infiltration, nutrient transport, and overall tissue integration. This contrasts with simpler methods like freeze-drying, which provide less precise structural control. Therefore, for design projects aiming to mimic natural tissue structures or create patient-specific implants, prioritizing these advanced fabrication techniques is essential for achieving optimal biological outcomes.
