Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • 3D Printing Technologies

Background:

  • Electrohydrodynamic Jet 3D Printing (e-jetting), derived from electrospinning, allows precise layer-by-layer fiber deposition for customized scaffold fabrication.
  • E-jetted scaffolds demonstrate efficacy in supporting cell attachment, proliferation, extracellular matrix formation, and cell infiltration due to well-defined pore structures.

Purpose of the Study:

  • To review the development and biomedical applications of e-jetting in tissue-engineered scaffold fabrication.
  • To highlight the potential of e-jetting for creating scaffolds with superior mechanical properties and controlled cellular behavior for specific applications like cartilage, tendon, and blood vessel regeneration.

Main Methods:

  • Review of existing literature on electrohydrodynamic Jet 3D Printing (e-jetting) techniques and applications.
  • Analysis of studies investigating scaffold design, printability, biomaterial incorporation, and cell responses in e-jetted constructs.

Main Results:

  • E-jetting enables the production of micrometer-scale fibers and well-defined structures, crucial for mimicking native tissue environments.
  • Combined e-jetting with other techniques allows incorporation of biomaterials like hydrogels and cell spheroids, enhancing scaffold biological performance.
  • E-jetted scaffolds have shown promise in regenerating various tissues, promoting cellular alignment and differentiation.

Conclusions:

  • E-jetting is a versatile and controllable 3D printing technique with significant potential for tissue engineering and regenerative medicine.
  • Further development is needed to address limitations such as large-scale construct printability and expanding the range of applicable biomaterials.
  • The ability to create multi-scale scaffolds with high biological mimicry and facilitate cellular infiltration positions e-jetting as a key tool for future tissue engineering endeavors.
