Summary

Additive Manufacturing (AM), commonly known as 3D printing, has revolutionized the way products are designed, optimized, and manufactured. By enabling layer-by-layer fabrication of complex geometries, AM allows for design freedom, customization, and material efficiency. This technology spans across multiple sectors, and offering solutions for rapid prototyping, tooling, and end-use part production. As the field continues to evolve, integrating advancements in materials science, computational design, and process control, optimizing these technologies becomes crucial for enhancing performance, cost-effectiveness, and sustainability. This special issue explores the design strategies, optimization techniques, and diverse applications of AM technologies, highlighting their transformative potential in modern manufacturing. From topology optimization to material selection, the goal is to provide insights into how AM can be effectively leveraged to address complex engineering challenges, push the boundaries of innovation, and contribute to Industry 4.0 initiatives.


This special issue welcomes original research articles and review articles. Research areas include (but are not limited to) the following topics:

• Design strategies for AM/ Design for additive manufacturing (DfAM)

• Design of new additive manufacturing technologies

    Porosity-Impact Strength Relationship in Material Extrusion: Insights from MicroCT, and Computational Image Analysis

    Jia Yan Lim, Siti Madiha Muhammad Amir, Roslan Yahya, Marta Peña Fernández, Tze Chuen Yap
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2025.070707
    (This article belongs to the Special Issue: Design, Optimisation and Applications of Additive Manufacturing Technologies)
    Abstract Additive Manufacturing, also known as 3D printing, has transformed conventional manufacturing by building objects layer by layer, with material extrusion or fused deposition modeling standing out as particularly popular. However, due to its manufacturing process and thermal nature, internal voids and pores are formed within the thermoplastic materials being fabricated, potentially leading to a decrease in mechanical properties. This paper discussed the effect of printing parameters on the porosity and the mechanical properties of the 3D printed polylactic acid (PLA) through micro-computed tomography (microCT), computational image analysis, and Charpy impact testing. The results for both… More >

    Abstract Additive manufacturing (AM), a key technology in the evolution of Industry 4.0, has revolutionized production processes by enabling the precise, layer-by-layer fabrication of complex and customized components, enhancing efficiency and flexibility in smart manufacturing systems. However, one significant challenge hindering the acceptance of this technology is the limited print size, constrained by the machine’s small bed. To address this issue, a suitable polymer joining technique could be applied as a post-fabrication step. The present article examines findings on the Ultrasonic Welding (UW) of Material Extrusion (MEX)-3D printed parts made from commonly used thermoplastics, Acrylonitrile Butadiene… More >

    Ilesanmi Afolabi Daniyan, Rumbidzai Muvunzi, Festus Fameso, Julius Ndambuki, Williams Kupolati, Jacques Snyman
    CMC-Computers, Materials & Continua, Vol.83, No.2, pp. 1623-1648, 2025, DOI:10.32604/cmc.2025.062092

    Abstract This study evaluates the Fuzzy Analytical Hierarchy Process (FAHP) as a multi-criteria decision (MCD) support tool for selecting appropriate additive manufacturing (AM) techniques that align with cleaner production and environmental sustainability. The FAHP model was validated using an example of the production of aircraft components (specifically fuselage) employing AM technologies such as Wire Arc Additive Manufacturing (WAAM), laser powder bed fusion (L-PBF), Binder Jetting (BJ), Selective Laser Sintering (SLS), and Laser Metal Deposition (LMD). The selection criteria prioritized eco-friendly manufacturing considerations, including the quality and properties of the final product (e.g., surface finish, high strength,… More >
