The medical industry has taken a leadership role in adopting and deploying Melt Electro writing Technology in Korea, owing largely to substantial government assistance.
Healthcare is the most important of the government's ten priority areas, as defined in the Melt Electro writing Technology plan. Furthermore, the government's pilot programs to "stimulate fresh demand" are mostly aimed at the healthcare business. This means that, from the government's perspective, healthcare Melt Electro writing Technology applications provide the quickest victories at the outset. By the end of 2016, the Ministry of Food and Drug Safety had formally registered 19 3D-printed medical items, principally orthopaedic implants, thanks to government funding.
Singapore has prioritized the development of the country's Melt Electro writing Technology business. Singapore's government launched the Research, Innovation, and Enterprise (RIE) 2020 strategy, which highlighted AM as a vital enabler to promote the growth and competitiveness of the national manufacturing industry. The creation of the National Additive Manufacturing Innovation Cluster (NAMIC) in 2015 was possibly the most significant government move to boost AM. NAMIC finds and develops AM start-ups and innovations, as well as kick-starts public-private partnerships.
Melt electrowriting (MEW) is a cutting-edge additive manufacturing process that deposits preset micrometric strands. However, due to the necessity to eliminate polymer jet instabilities, it has thus far been naturally constrained to basic planar and tubular scaffold designs.
The fabrication of fibrous scaffolds with customized micrometric characteristics and anatomically appropriate three-dimensional (3D) geometries for soft tissue engineering applications continue to be a significant problem. Melt electrowriting (MEW) is a cutting-edge additive manufacturing process that deposits preset micrometric strands. However, due to the necessity to eliminate polymer jet instabilities, it has thus far been naturally constrained to basic planar and tubular scaffold designs. In this paper, they push the technological limitations of MEW to create complex fibrous scaffolds with regulated micrometric and patient-specific anatomic characteristics.
Melt electrowriting (MEW) is a new high-resolution additive manufacturing technology based on electrohydrodynamic polymer processing. MEW is most commonly employed to make scaffolds for biomedical purposes, where the microscale fibre location has a significant impact on the macroscopic mechanical characteristics. This paper provides an update on the growing number of polymers processed using MEW as well as several commercial sources of the gold standard poly(-caprolactone) (PCL). A description of MEW-processed polymers other than PCL, such as blends and coated fibres, is provided to give special benefits in biomedical applications. Furthermore, a viewpoint on printer designs and improvements is presented in order to continue extending the range of processable polymers for MEW.
Because of the possibility of patient-specific designs, additive manufacturing (AM) is becoming more popular in biomaterials, tissue engineering, and biofabrication. Every fabrication process has an optimal printing resolution range, which for many techniques is 50-500 m. It is important to be able to print increasingly smaller structural elements at the low micrometre or nanometer scale for biological applications that aim to replicate tissue microarchitecture. Electrohydrodynamic (EHD) methods such as solution electrospinning (SES) melt electrospinning (MES), and melt electrowriting can help achieve such tiny fibre diameters (MEW). This study focuses on the later AM technology, emphasizing the various materials employed and providing a future outlook on the material alternatives for this approach.
The recent invention of electrostatic writing (electro writing) using molten jets gives a possibility to address several key tissue engineering difficulties. An applied voltage is used to create a steady fluid jet with a predictable course that is continually deposited onto a collector. The fibre diameter varies during the procedure, and it is suitable for clinically used polymers. Melt electro writing offers the potential for clinical translation if the implant's biological effectiveness can be enhanced above existing gold standards. It offers scientists a one-of-a-kind chance to conduct low-cost, high-resolution additive manufacturing research that is ideally positioned for clinical translation while utilising current regulatory frameworks.
The creation of biological grafts that resemble the composition, structure, and mechanical behaviour of natural tissue is required for successful cartilage engineering. Melt-electro writing (MEW) was utilised to create arrays of polymeric structures whose role was to direct the formation of spontaneously created cellular aggregates inside these structures, as well as to give tensile reinforcement to the emerging tissues. Inkjet was used to deposit specific quantities of cells into MEW structures, which self-assembled into an orderly array of spheroids within hours, resulting in a hyaline-like hybrid tissue.
The manufactured cartilage was structurally similar to the historical arrangement seen in skeletally immature synovial joints. In less than 15 minutes, this biofabrication framework was utilised to create scaled-up (50mm) cartilage implants comprising over 3,500 cellular aggregates. After 8 weeks in culture, the compressive characteristics of these MEW-reinforced tissues increased 50-fold. Helium ion microscopy revealed the formation of an arcing collagen network within the created tissue. This hybrid bioprinting technology enables the development of cartilage biomimetic grafts for biological joint resurfacing in a varied and scalable manner.
The Melt electro writing (MEW) employs voltage-stabilized jets to precisely position low-micrometre-scale fibres in 3D space. The fibre diameter ranges from 820 nm to 140 m, whereas it is often greater than 200 m with FDM, restricting this additive manufacturing technology's ability to make fully biomimetic implants. MEW, on the other hand, allows for the creation of extremely porous (80-98 vol per cent pore volume), complex, and biomimetic scaffolds. MEW has been utilised, for example, to simulate the anisotropy of the collagen network in cartilage, mechanically reinforcing hydrogels in a way that mimics the behaviour of collagens in cartilage. MEW scaffolds have also been employed as a platform for pre-formed multicellular spheroids assembly.

The electrohydrodynamic stability of direct-written fluid jets is being investigated for the purpose of designing and manufacturing tissue engineering scaffolds with the necessary fibre diameters. Melt electro writing is shown to be capable of producing a wide range of fibres with distinct diameters (2-50 m) using a single nozzle. This change in fibre diameter is controlled digitally by combining the mass flow rate to the nozzle with variations in collector speed without affecting the applied voltage. The broadest range of fibre diameters was obtained by changing those parameters simultaneously during printing. The maximum placement accuracy might be obtained by keeping the collector speed slightly faster than the essential translation speed.
This enables the construction of sophisticated multimodal and multiphase scaffolds from medical-grade poly (-caprolactone) using a single nozzle in a single print. Controlling fibre diameter during printing brings up new design possibilities for precise scaffold creation in biological applications.
The concepts of additive manufacturing (AM) have been used in the construction of 3D scaffolds for tissue engineering (TE), including the regeneration of bone, cartilage and skin. AM is very useful for providing tailored therapy, and one facet of this is the creation of multiphasic scaffolds to mimic regional changes in tissue ultrastructure. In this context, multiphasic scaffolds are described as having diverse regional morphologies from one another. Multiphasic scaffolds have a wide range of applications in TE when combined with a method that closely mimics the native tissue ultrastructure.
Furthermore, bimodal/multimodal fibrous scaffolds provide a variety of size characteristics within each zone and often comprise tiny diameter fibres to enhance cell adherence while bigger fibres preserve the overall construct's structural integrity. The small diameter fraction is typically created using solution electrospinning, whilst the larger diameter fibres are created using a variety of techniques such as melt spinning, fused deposition modelling (FDM), or a different electrospinning configuration. Due to a more straightforward regulatory route to clinical translation, melt processing was chosen in this work.
The heart valves are highly flexible but durable, with complicated deformation properties including anisotropy, nonlinearity, and viscoelasticity that are only partially replicated in scaffolds for heart valve tissue engineering (HVTE). The structural characteristics and microarchitecture of the primary tissue constituents, particularly collagen fibres, define these biomechanical traits.
Melt electrowetting (MEW) is used to build functional scaffolds with highly regulated fibrous microarchitecture that imitate the wavy character of collagen fibres and their load-dependent recruitment. As established by quasistatic and dynamic mechanical characterization, scaffolds with well-specified serpentine designs recreate the J-shaped strain stiffening, anisotropic, and viscoelastic behaviour of natural heart valve leaflets. They also increase the development of human vascular smooth muscle cells sown directly or in fibrin encapsulation, as well as the deposition of valvular extracellular matrix components.
Three-dimensional printed hydrogel constructions with well-organized melt electrowritten (MEW) fibre-reinforcing scaffolds have been shown to be a potential restorative technique for treating minor cartilage lesions. Scientists are investigating ways to convert the manufacturing of tiny fibre-reinforced structures on flat surfaces into anatomically meaningful structures. Their work demonstrates that therapeutically important materials with low conductivities may be resurfaced with ordered MEW fibres. Importantly, precise patterning on non-flat surfaces was demonstrated.
Regenerative techniques based on biofabrication technology may be a viable option for repairing damaged articular cartilage tissue. Recent advancements in (micro) fibre production and deposition methods, such as melt electro writing (MEW) and extrusion-based bioink deposition, have enabled the fabrication of mechanically stable, fibre-reinforced cartilage implants.
