Near-field electrospinning and melt electrowriting involve extruding fibers with the force of an electric field and collecting them before bending occurs, allowing for precise control and customization of scaffold geometry for biomedical applications. Limitations in direct fiber writing include standardization, throughput, and ease of creating complex geometries.
Near-field electrospinning (NFES) and melt electrowriting (MEW) are the process of extruding a fiber due to the force exerted by an electric field and collecting the fiber before bending instabilities occur. When paired with precise relative motion between the polymer source and the collector, a fiber can be directly written as dictated by preprogrammed geometry. As a result, this precise fiber control results in another dimension of scaffold tailorability for biomedical applications. In this review, biomedically relevant polymers that to date have manufactured fibers by NFES/MEW are explored and the present limitations in direct fiber writing of standardization in published setup details, fiber write throughput, and increased ease in the creation of complex scaffold geometries are discussed.
