Special Issue Information

Dear Colleagues,

Additive manufacturing (AM) technology has revolutionized the design and fabrication of products by enabling the development of novel materials to achieve multi-functional properties. Advanced materials and multiscale structures have enabled the optimization of the overall properties of components. Despite researchers’ continued efforts, materials suitable for AM processes still appear to be a major bottleneck in its acceptance for use in manufacturing industries and other sectors involving the customization and personalization of products.

This Special Issue, titled “Development of Advanced Materials Using Additive Manufacturing Technologies”, will provide a platform for researchers and practitioners to share novel ideas and research regarding the design, processing, and characterization of novel and advanced materials, such as high-performance polymers, composite materials, metallic alloys, high-entropy alloys, biomaterials, and functional ceramics, using AM technologies. It aims to cover all the fundamentals of the processing, synthesis, structure, composition, and performance of advanced materials designed or modified via AM processes.

We invite authors to submit full-length articles with original research, review papers, and communications for inclusion this Special Issue focusing on the development of advanced materials using AM technologies.

Increased usage of selective laser sintering (SLS) for the production of end-use functional components has generated a requirement of developing new materials and process improvements to improve the applicability of this technique. This article discusses a novel process wherein carbon black was applied to the surface of TPU powder to reduce the laser reflectivity during the SLS process. The printing was carried out with a preheating temperature of 75 °C, laser energy density of 0.028 J/mm2, incorporating a 0.4 wt % addition of carbon black to the TPU powder, and controlling the powder layer thickness at 125 μm. The mixed powder, after printing, shows a reflectivity of 13.81%, accompanied by the highest average density of 1.09 g/cm3, hardness of 78 A, tensile strength of 7.9 MPa, and elongation at break was 364.9%. Compared to commercial TPU powder, which lacks the carbon black coating, the reflectance decreased by 1.78%, mechanical properties improved by 33.9%, and there was a notable reduction in the porosity of the sintered product.

Continuous fiber-reinforced material extrusion is an emerging additive manufacturing process that builds components layer by layer by extruding a continuous fiber-reinforced thermoplastic strand. This novel manufacturing process combines the benefits of additive manufacturing with the mechanical properties and lightweight potential of composite materials, making it a promising approach for creating high-strength end products. The field of design for additive manufacturing has developed to provide suitable methods and tools for such emerging processes. However, continuous fiber-reinforced material extrusion, as a relatively new technology, has not been extensively explored in this context. Designing components for this process requires considering both restrictive and opportunistic aspects, such as extreme anisotropy and opportunities for functional integration. Existing process models and methods do not adequately address these specific needs. To bridge this gap, a tailored methodology for designing continuous fiber-reinforced material extrusion is proposed, building on established process models. This includes developing process-specific methods and integrating them into the process model, such as a process selection analysis to assess the suitability of the method and a decision model for selecting the process for highly stressed components. Additionally, a detailed design process tailored to continuous fiber-reinforced material extrusion is presented. The application of the developed process model is demonstrated through a case study.
