Melt electrowriting (MEW) is an emerging additive manufacturing technique that enables the precise deposition of molten polymer fibers with micron-scale precision, offering significant potential in biomaterial scaffold fabrication. MEW allows for the creation of highly ordered structures and fiber diameters that are difficult to achieve with other extrusion-based 3D printing techniques. This technique is particularly promising for creating scaffolds that mimic the physical properties of the extracellular matrix (ECM), supporting cell attachment, proliferation, and tissue regeneration. Recent advancements in MEW have included the development of more complex collector plate systems, fiber patterning, and a broader range of printable materials, enabling the fabrication of scaffolds with tailored mechanical and biological properties. The choice of biomaterials in MEW scaffolds is crucial for modulating cell attachment and proliferation. Polycaprolactone (PCL) is a widely used thermoplastic due to its biocompatibility, biodegradability, and ease of fabrication. However, its hydrophobic nature limits cell adhesion, necessitating surface modifications such as plasma treatment or the use of coatings like gold to enhance conductivity and promote cell growth. Other polymers and polymer composites, including polypropylene, polylactic acid, and bioactive ceramics, have also been explored for their ability to enhance scaffold functionality and bioactivity. Incorporating cells and biomolecules into MEW scaffolds has been a focus of research, with techniques such as covalent immobilization of growth factors and the use of water-soluble materials enabling the fabrication of cell-laden scaffolds. The integration of cells and biomolecules into MEW scaffolds allows for the creation of more complex and functional biological systems, enhancing tissue regeneration and cell therapy applications. MEW scaffold architecture plays a critical role in influencing cell behavior. The design of scaffolds, including crosshatch, sinusoidal, auxetic, and multiphasic structures, can significantly affect cell proliferation, differentiation, and tissue formation. These architectures provide controlled environments that mimic the complex structures of native tissues, promoting the development of biomimetic systems. Computational modeling and prediction tools are essential for understanding and optimizing cell proliferation patterns on MEW scaffolds. These models help in simulating and predicting tissue growth, enabling the design of more effective biomimetic systems. The integration of advanced materials, scaffold design, and computational biology is paving the way for the development of highly efficient and functional scaffolds in tissue engineering and regenerative medicine. Future directions in MEW research include the development of smart materials, the incorporation of biologics, and the use of dynamic bioreactor systems to create more physiologically relevant environments for cell growth and tissue regeneration.Melt electrowriting (MEW) is an emerging additive manufacturing technique that enables the precise deposition of molten polymer fibers with micron-scale precision, offering significant potential in biomaterial scaffold fabrication.
