Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Polymer Science

Background:

  • Designing ideal three-dimensional (3-D) scaffolds is crucial for soft and hard tissue regeneration.
  • Biomedical scaffolds require biodegradability, biocompatibility, and structural support for cell adhesion and growth.
  • Rapid prototyping offers versatile methods for fabricating customized polymeric scaffolds.

Purpose of the Study:

  • To fabricate polycaprolactone (PCL) scaffolds using a 3-D melt plotting system.
  • To compare the properties of 3-D plotted PCL scaffolds with those fabricated via salt leaching.
  • To evaluate the mechanical properties and cell morphology on both types of scaffolds.

Main Methods:

  • Fabrication of PCL scaffolds using a 3-D melt plotting system and salt leaching.
  • Characterization of scaffold geometry and mechanical properties using scanning electron microscopy, laser scanning microscopy, micro-computed tomography, and dynamic mechanical analysis.
  • Assessment of cell morphology and expansion on the fabricated scaffolds.

Main Results:

  • 3-D plotted scaffolds exhibited easily adjustable mechanical properties through geometry modification.
  • The plotted scaffolds provided superior space for cell expansion between scaffold strands compared to salt-leached scaffolds.
  • Both methods produced scaffolds with interconnecting pores suitable for tissue engineering.

Conclusions:

  • 3-D melt plotting is a viable technique for fabricating PCL scaffolds with tunable mechanical properties.
  • This method enhances cell expansion potential, making it advantageous for tissue regeneration applications.
  • The ability to customize scaffold geometry offers significant potential in biomaterials and tissue engineering.
